7. Audio Input (Terminal Block) Connectors

Connect your audio source outputs to these inputs using the provided plug-in connectors. One 6-pin plug-in connector can be used per input pair. These inputs are high impedance, balanced connections. See "Wiring Input Connectors" on page 7 for information on wiring these connectors.

*WARNING: Only connect to networks that remain inside the building.

Hardware Setup

Connecting the AC Power Cord

IMPORTANT: The amplifier output mode must be properly configured for the application before connecting the speakers and powering on the amplifier. By default, all outputs are configured for Low Z operation. See "Configuring the Amp" on page 11 for more information.

Connect your amplifier to the AC mains power outlet using the supplied AC power cord. First, connect the IEC end of the cord to the IEC connector on the amplifier. Then plug the other end of the cord to the AC mains.

WARNING: The third prong of the power connector (ground) is an important safety feature. Do not attempt to disable this ground connection by using an adapter or other methods.

Make certain the AC mains voltage and current ratings are sufficient to deliver full power to all amplifiers. CDi DriveCore Series amplifiers use a universal power supply. The AC voltage requirements are 100V-240V\~, 50/60Hz ( ± 10%). If the AC line voltage varies outside of this acceptable range, the amplifier's power supply will turn off and the blue Power LED will flash. The amplifier will turn back on when the AC line voltage returns to safe operating levels.

Power Up Procedure

When turning on the amplifier for the first time:

1. Ensure all connections are disconnected with the exception of the power cord.
2. Press the amplifier's POWER button. The Power indicator will light blue and the amplifier will boot as long as sufficient mains power is provided.

3. Once boot up is complete, turn the ENCODER counter-clockwise until all amp levels are set to -80dB in the front panel LCD.

4. Configure the amplifier as described in "Configuring the Amp" on page 11.

NOTE: The amplifier output mode must be properly configured for the application before connecting the speakers and powering on the amplifier. By default, all outputs are configured for Low Z operation.

1. Once the amplifier has been properly configured for the application, turn off the power — by pressing and holding the Power button for 2 seconds — then disconnect the power cord.

2. Turn down the level of your audio source.

3. Make all connections as described in "Wiring Input Connectors" and "Wiring Output Connectors" on page 7.

4. Once all connections have been made, reconnect the power cord and turn on the amplifier power.

5. Turn your audio source up to an optimum level. Refer to all device meters and ensure that at no point in the signal chain is the signal being clipped in any way. If any of the amplifier's Clip indicators light yellow, reduce the source level until the Clip LEDs no longer light.

6. Turn the amplifier's ENCODER clockwise until the desired loudness or power level is achieved, while making sure the amplifier's clip LEDs do not light.

IMPORTANT: Always turn off the amplifier — by pressing and holding the Power button for 2 seconds — and disconnect the power cord before making any wiring or installation changes.

IMPORTANT: When powering a fully configured PA system, always turn the amplifiers on last and off first.

For help with determining your system's optimum gain structure (signal levels) please refer to the Crown Amplifier Application Guide, available online at www.crownaudio.com.

Precautions

Your amplifier is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety:

1. Configure the amplifier for proper operation, including input and output wiring hookup. Improper wiring can result in serious operating difficulties. For information on wiring and configuration, please consult "Wiring Input Connectors" and "Wiring Output Connectors" on page 7. For advanced setup techniques, consult Crown's Amplifier Application Guide available online at www.crownaudio.com.

2. Use care when making connections, selecting signal sources, and controlling the output level. The load you save may be your own!

3. Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and cause oscillations.

4. Never connect the output to a power supply, battery, or power main. Electrical shock may result.

5. Tampering with the circuitry or making unauthorized circuit changes may be hazardous and invalidate all agency listings.

6. Do not operate the amplifier with the Clip LEDs constantly flashing.

7. Do not overdrive the mixer, which will cause clipped signal to be sent to the amplifier. Such signals will be reproduced with extreme accuracy, and loudspeaker damage may result.

8. Do not operate the amplifier with less than the rated load impedance. Due to the amplifier's output protection, such a configuration may result in premature clipping and speaker damage.

REMEMBER: Crown is not liable for damage that results from overdriving other system components.

Wiring Input Connectors

Crown recommends using pre-built or professionally wired balanced cables (two-conductor plus shield). Balanced wiring provides better rejection of unwanted noise and hum, however, unbalanced line may also be used.

Use 6-pin plug-in cable ends at the amp input connectors. A male connector is supplied for each input of your model of amplifier. Additional connectors are available from Crown (P/N 5024623).

Figure 4 shows connector pin assignments for balanced wiring and Figure 5 shows connector pin assignments for unbalanced wiring. Note that for bridge mono operation, only the odd-numbered input channels (1,3) should be wired for each bridged pair.

INPUT SHEILD SOURCE

- + + - SHIELD + SOURCE INPUT

Figure 5: Unbalanced wiring

Wiring Output Connectors

IMPORTANT: The amplifier output mode (Low Z, 70V, 100V) must be properly configured for the application before connecting the speakers. By default, all outputs are configured for Low Z operation. See "Configuring the Amp" on page 11 for more information.
Before making any output connections, ensure the power cord is disconnected from the amplifier and carefully review the total impedance for loudspeakers connected to each amplifier output. If multiple loudspeakers are connected to an output in Low Z mode (i.e., in series, parallel, or series-parallel), be certain the total system impedance is within allowed specification for the output. When multiple loudspeakers are connected to one output in High Z mode, be certain total tapped power is below the rated power output for the channel. See "Specifications" on page 78 for supported load specifications.
NOTE: The Crown-designed output cover does not need to be removed to connect the output wiring.
Crown recommends using the included terminal fork connectors and two-conductor or four-conductor, heavy gauge speaker wire. You may use terminal forks up to 10 AWG or bare wire for your output connectors (see Figure 6). For best results, Crown recommends Panduit part #PV10-6LF-L or equivalent terminal fork. For bare wire, it is highly recommended that output wiring is tinned. To reduce strain on input and output wiring, Crown recommends the use of horizontal lacer bars. For best results, Crown recommends Middle Atlantic® part# LBP-4R90 or equivalent horizontal lacer bar.
For low-impedance loads, refer to the table below and select the appropriate size of wire based on the distance from amplifier to speaker.

Distance Wire Size
Up to 25 ft. (7.6m) 16 AWG
26-40 ft. (7.9-12.2m) 14 AWG
41-60 ft. (12.5-18.3m) 12 AWG
>60 ft (18.3m) 10 AWG

CLASS 2 WIRING - 2 + 1 OUTPUT

Figure 6: Wiring output connectors

CAUTION: Never use shielded cable for output wiring.

CAUTION: Never connect the speaker return to the chassis of the amplifier, or damage to the amplifier may result.

NOTE: Custom wiring should only be performed by qualified personnel. Class 2 output wiring is required.

For application-specific output connection diagrams, including how to wire outputs for bridge mono operation, see "Application Examples" on page 55.

Delay

The CDi DriveCore amplifiers have an Input Delay (pre-crossover) and Output Delay (post-crossover) DSP module for each channel. Each is selectable when navigating the Speaker Tunings/DSP screen (see Figure 16). Once an Input or Output Delay module has been selected, delay settings can be edited from the Delay screen (see Figure 17).

The Output Delay can be used to time-align the various drivers in a multi-way speaker system or for close-proximity zone delay (to compensate for the slap-delay artifacts caused when bleed from an adjacent zone is audible). A total of up to 100ms of delay time is available in each Output Delay. The Input Delay can be used for delaying the system to the stage backline, delay fills, zone delay, or whenever more delay time is required than the Output Delay has to offer. The Input Delays provide an additional 1 second of delay time for each channel. Delay can be adjusted in milliseconds, feet, or meters.

Figure 23: BLU link Settings menu

Available options:

• Sample Rate (48kHz, 96kHz)

Sets the BLU link sample rate in the amplifier. Sample rate can be set to 48kHz (default) or 96kHz. When set to 48kHz, the amplifier can access BLU link channels 1-256. When set to 96kHz, the amplifier can access BLU link channels 1-128.

NOTE: The sample rate must be set to match all other devices on the BLU link bus in order to pass BLU link audio.

NOTE: The CDi DriveCore amplifiers process audio using a fixed 96kHz internal sampling rate. When using a BLU link sample rate of 48kHz, the audio signal from the BLU link bus will be sample rate converted from 48kHz up to 96kHz when entering the amp, and any audio signals sent from the amp back to the BLU link bus will be converted from 96kHz down to 48kHz.

NOTE: If the amp is configured to use any BLU link channels between 129-256 and the sample rate is then changed from 48kHz to 96kHz, all BLU link assignments above 128 will default back to an "unassigned" state since they will no longer be applicable at 96kHz.

- Priority (0-254)

Determines which device on the BLU link bus will provide audio clock for the entire bus. The higher the value, the higher the priority. Under certain conditions, such as when two devices have the same Priority settings, other factors may be used to determine BLU link clock priority (see "Mastership" on page 61 for more information).

- BLU link Channel Output 1-4\* (Off, 1-254 @ 48kHz / 1-128 @ 96kHz)

The CDi DriveCore amplifiers are capable of outputting up to 2 channels (2-channel models) or 4 channels (4-channel models) of audio onto the BLU link bus. These options allow you to assign the desired BLU link output channels. Channels 1-256 are available when using a 48kHz BLU link sample rate and channels 1-128 are available when using a 96kHz BLU link sample rate.

- BLU link Source Output 1-4\*

These options allow you to select the source to route to each BLU link output channel, with the following options available:

• Analog Input 1-4* (routes the pre-processed audio signal from the input)
• Amp Output 1-4* (routes the same audio signal present at the amplifier outputs)

For information on routing BLU link channels to the amplifier's inputs, see "Assigning Input Sources" on page 14.

For information on configuring BLU link output settings in Audio Architect, see "Configuring BLU link Outputs" on page 38.

*Channel 3 and 4 options available in 4-channel CDi DriveCore models only.

The latest version of Audio Architect can be downloaded at www.audioarchitect.harmanpro.com/en-US/software. To communicate with Audio Architect, the amplifier must be connected to a TCP\IP network via the rear panel Ethernet port and, in some cases, configured for the network.

NOTE: The BLU link ports available on BLU link CDi DriveCore models cannot be used for network control and monitoring of the amplifier.

When Audio Architect is first loaded, the software will scan the network for HiQnet devices. All devices that are discovered on the network will be found under the Device Tree menu in the left-hand side of the Main Audio Architect window (see Figure 24).

NOTE: If devices are not discovered and displayed in the Device Tree menu as shown above, the device and/or network may not be configured correctly. See "Configuring Amplifier Network Settings" on page 24 for information on configuring network settings.

Configuring Amplifier Network Settings

Network settings can be configured from either the CDi DriveCore's front panel or from the NetSetter software application. DHCP is enabled by default, allowing the CDi DriveCore amplifiers to automatically obtain an IP address when connecting to an Ethernet switch or router with an active DHCP server, or when using Auto-IP.

Configuring the Network from the Front Panel

To configure the amplifier's network settings from the front panel:

1. From the Home screen, press the MENU button.
2. Select the "Network" option from the menu using the ENCODER.
3. Use the ENCODER to select and edit network settings.
4. When done, select "Save" then "Done" at the bottom of the screen for the changes to take affect.

TIP: To quickly configure multiple HiQnet devices, connect all the devices and configuration computer to the same network and use the NetSetter software application (see "Configuring the Network using NetSetter" on page 25).

• Gateway
  Allows for viewing and editing of the gateway address, if required to access the network. If using a router, the gateway address will typically be the router address.
  • HiQnet
  Allows for viewing and editing of the HiQnet node address. Each device on a HiQnet network must have a unique node address.

For additional information on network configuration, please visit www.audioarchitect.harmanpro.com.

Configuring the Network using NetSetter

NetSetter is a software tool which enables you to discover HiQnet devices and reconfigure their network settings in real time, from one central location. Its function is to configure a system of devices to interoperate correctly on the same network and resolve conflicts quickly and easily. The latest version of NetSetter can be downloaded at www.audioarchitect.harmanpro.com/en-US/software.

The top of the NetSetter window displays overall operational functions that are available. At the bottom of the NetSetter window is an informational section that lists the number of discovered devices and the IP address of the DHCP server (if available). There is also information regarding the PC HiQnet Address, IP Address, and Subnet Mask.

All devices which have been discovered with DHCP/Auto-IP enabled and those which have been set to use DHCP/Auto-IP on applying the edits are displayed.

3. Rescan Network

Clicking this button re-scans the network to which the currently selected NIC is connected.

4. Export

Clicking this button brings up a "Save As" window, allowing you to save the HiQnet Addresses and IP Configurations of all devices on the network as a .CSV (Comma Separated Values) formatted file. This allows you to archive the information and open it in a spreadsheet program such as Microsoft® Excel®.

5. Proxies

This feature is used to connect to devices that cannot automatically be located by Audio Architect due to network configuration or security measures via proxy connections.

6. Static Routes

This feature is used to set up a static route and connect directly to a device located on a different subnet than the PC.

7. Clear Container

Resets the Container/Position Venue data of the selected device. The action occurs on either "Apply Current Edits" or "Apply and Exit" so that changes may be undone with the Undo Current Edits button.

8. Undo Current Edits

Resets any open edits in the grid to the values as currently on the network.

9. Apply Current Edits

Confirms any open edits in the grid. Devices update accordingly until connection is re-established with HiQnet NetSetter.

10. Apply and Exit

Confirms and saves any open edits in the grid. Devices update accordingly until connection is re-established with HiQnet.

NOTE: If you have made changes to NetSetter and attempt to exit the program, the confirmation window shown in Figure 27 will appear. Clicking OK will apply the edits you have made since opening NetSetter. Clicking Cancel will return you to the program.

Figure 28: NetSetter grid

1. MAC Address

Displays the MAC address of the discovered device. The data in this field cannot be edited.

NOTE: If more than one MAC address is discovered for a single device (e.g., HiQnet device MAC address, AVB card MAC address, etc.), the field will be represented as a dropdown menu and the desired MAC address can be selected from the list. For a device connected to the same control network with two control MAC addresses, the MAC address field will be displayed in red.

2. DHCP/Auto-IP

If the discovered device is configured to use DHCP/Auto-IP, this checkbox will be checked. If the discovered device is not using DHCP/Auto-IP, you may check the box so it will do so on applying edits. The device row will then become selected. The device will attempt to have its IP settings configured by DHCP on applying the edits; if no DHCP server is present, the device will attempt to have IP settings configured by Auto-IP.

All devices in the current filter view may be configured with DHCP/Auto-IP enabled by checking the checkbox in the column header — the individual checkboxes for all devices will become checked. If a single individual checkbox for a device is subsequently unchecked, the column header DHCP/Auto-IP checkbox will be automatically unchecked. Conversely, all devices in the current filter view can be configured with DHCP/Auto-IP disabled by unchecking the checkbox in the column header.

DHCP server status will be among the information displayed at the bottom of the NetSetter window. If a DHCP server is not detected, the information will read "DHCP server not detected". Note that checking a device's DHCP/Auto-IP checkbox has no immediate effect on the column sort order.

NOTE: Once edits have been made, it is critical to click the Apply Current Edits or Apply and Exit buttons for the changes to take affect.

3. IP Address

Displays the IP address of the discovered device. A valid IP address may be edited inline. If the edited value scopes the device out of the current Display filter, it will not be visible.

NOTE: A discovered device with an IP address that conflicts with that of another, already discovered device will be displayed in red. A conflicting IP address may be edited inline if you wish to change the device IP address on applying current edits. If DHCP/Auto-IP is enabled, the IP address field may not be edited inline.

NOTE: Once edits have been made, it is critical to click the Apply Current Edits or Apply and Exit buttons for the changes to take affect.

4. Subnet Mask

Displays the Subnet Mask of the discovered device. The Subnet Mask may be edited inline. The device row will be ordered accordingly with the current column sort immediately on successful editing of the field. The device row will remain selected.

NOTE: If DHCP/Auto-IP is enabled, the Subnet Mask field may not be edited inline.

NOTE: Once edits have been made, it is critical to click the Apply Current Edits or Apply and Exit buttons for the changes to take affect.

5. Default Gateway

Displays the Default Gateway of the discovered device. The Default Gateway may be edited inline. The device row will be ordered accordingly with the current column sort immediately on successful editing of the field. The device row will remain selected.

NOTE: If DHCP/Auto-IP is enabled, the Default Gateway field may not be edited inline.

If the device is being rediscovered, then the following behavior will occur:

• When the device is not selected, the device Default Gateway address field is displayed but is grayed out.
• When the device is selected and highlighted in orange, the field is represented in dark gray.

NOTE: Once edits have been made, it is critical to click the Apply Current Edits or Apply and Exit buttons for the changes to take affect.

6. Device ID

Displays the HiQnet address of the discovered device. This field may be edited inline if you want to change the device HiQnet address. If the edited value scopes the device out of the current Display filter, it will not be visible and no devices will be selected. If devices are discovered with a conflicting HiQnet address, then the following will occur:

• The HiQnet ID field of a discovered device will be displayed in pink when a HiQnet address conflicts with that of another, already discovered HiQnet address.
• When the device is selected and highlighted in orange, the field is represented in red.
• The HiQnet address is not displayed, instead a dash is displayed as grayed out.

NOTE: A conflicting HiQnet address may be edited inline if you want to change the device HiQnet address.

NOTE: Devices are not discoverable at the IP level. A device which is not discoverable at the IP level (invalid IP address, etc.) will not be able to report a HiQnet address. In this instance, the HiQnet ID field will display a "?" to indicate that the field may exist but that the software does not have enough discoverability of the device to determine the value. A blank field or "-" implies the value is null and the HiQnet ID field may not be edited inline.

NOTE: Once edits have been made, it is critical to click the Apply Current Edits or Apply and Exit buttons for the changes to take affect.

7. Random ID Reboot

When enabled, the device will be given a random HiQnet address. If you want to set the HiQnet address of a device to a random ID, check the Random ID checkbox. If the checkbox is unchecked before applying current edits, the prior HiQnet ID value will be restored.

All devices in the current filter view may be set to Random HiQnet ID by checking the checkbox in the column header — the individual checkboxes for all devices will become checked. If any individual checkbox is subsequently unchecked, the column header Random ID checkbox will automatically be unchecked. Conversely, if all devices in the current filter view are set to Random ID on and the Random HiQnet ID column header checkbox is checked, all devices may be set to Random ID off by unchecking the column header checkbox — the individual checkboxes for all devices will become unchecked.

NOTE: Devices are not discoverable at the IP level. A device which is not discoverable at the IP level (invalid IP address, etc.) will not be able to report a HiQnet address. In this instance, the Random ID checkbox will be unavailable.

8. Status

Displays the current discovery status of the device. The Status field may not be edited. Discovery status hierarchy is as follows:

a. Discovered

If a device has a unique IP address and a unique HiQnet address, this condition will be shown unless the device is access controlled. When the device is not selected, the "Discovered" label is represented in green.

The "Discovered" status is determined by the following conditions:

• The device is discoverable at the MAC address level.
• The device has a valid and unique IP address (manual or DHCP/Auto-IP).
• The device has a unique HiQnet address.

- The device is not access controlled.

b. IP Conflict

If a device has an IP address conflict, this error will be shown regardless of other status notifications. When the device is not selected, the "IP conflict" label is represented in blue.

The "IP conflict" status is determined by the following conditions:

• The device is discoverable at the MAC address level.
• The device has an IP address that conflicts with another device which has already been discovered by NetSetter.

c. HiQnet Conflict

If a device has a unique IP address yet has a HiQnet address conflict, this error will be shown regardless of other status notifications. When the device is not selected, the "HiQnet conflict" label is represented in red.

The "HiQnet conflict" status is determined by the following conditions:

• The device is discoverable at the MAC address level.
• The device has a valid and unique IP address (manual or DHCP/Auto-IP).
• The device has a HiQnet address that conflicts with another device which has already been discovered by NetSetter.

d. Locked

If a device has a unique IP address and a unique HiQnet address, this condition will be shown if the device is access controlled. When the device is not selected, the "Locked" label is represented in yellow.

The "Locked" status is determined by the following conditions:

• The device is discoverable at the MAC address level.
• The device has a valid and unique IP address (manual or DHCP/Auto-IP).
  • The device has a unique HiQnet address.
  • The device is access controlled.

When a device has been discovered in a Locked state and any field is attempted to be edited for the first time, a dialog prompting for the Admin password will appear. Only a successful login with the Admin password will enable all fields to be edited. This state may need to be reset on rediscovery after applying current edits, requiring the Admin password to be entered again.

e. Discovering

This condition will be displayed if the device has had changes made to its IP configuration or HiQnet address and HiQnet NetSetter is waiting to re-establish connection. When a device being rediscovered is not selected, all fields within the device row are displayed but grayed out.

The "Discovering" status is determined by the following conditions:

• The device had been previously discovered at the MAC address level.
• Edits had been made to one or more fields.
• The device is being rediscovered after applying current edits.

NOTE: Since the sort order automatically updates when a field within the sorted column is updated, the rediscovered device will occupy the same row on rediscovery. The exception is when DHCP/Auto-IP or Random ID has been set prior to applying current edits, in which case the rediscovered device will occupy the appropriate row in the current column sort order.

9. Device Type

The device class name is displayed here, as reported by the discovered device. To the left of each device class name, the brand icon is displayed. The software application name is displayed for discovered PCs running an instance of HiQnet software. HiQnet software programs include System Architect, Audio Architect, and Performance Manager.

NOTE: The Device Type field may not be edited inline.

NOTE: Devices are not discoverable at the IP or HiQnet level. A device which is not discoverable at the IP level (invalid IP address, etc.) or HiQnet address level (HiQnet address conflict, etc.) will not be able to report its class name. In this instance, the Device Type field will display a "?" to indicate that the field may exist but that the software does not have enough discoverability of the device to determine the value. A blank field or "-" implies the value is null.

10. Device Name

The user-definable Device Name is displayed here, as reported by the discovered device.

NOTE: This field may be edited inline if you want to change the Device Name. This field may not be edited for discovered PCs running an instance of HiQnet software.

NOTE: Devices are not discoverable at the IP or HiQnet level. A device which is not discoverable at the IP level (invalid IP address, etc.) or HiQnet address level (HiQnet address conflict, etc.) will not be able to report its Device Name. In this instance, the Device Name field will display a "?" to indicate that the field may exist but that the software does not have enough discoverability of the device to determine the value. A blank field or "-" implies the value is null.

NOTE: Once edits have been made, it is critical to click the Apply Current Edits or Apply and Exit buttons for the changes to take affect.

11. Container : Position

The Container and Position Venue Data is displayed here (separated by a colon), as reported by the discovered device. The field is left blank for discovered PCs running an instance of HiQnet software. HiQnet software programs include System Architect, Audio Architect, and Performance Manager.

TIP: A selected device may have its Venue Data cleared (including all Building, Floor, and Room Venue data) by pressing the Clear Container button. This action takes place on applying current edits only and can be undone with the Undo Current Edits button.

NOTE: The Container/Position Venue Data may not be edited inline.

NOTE: Devices are not discoverable at the IP or HiQnet level. A device which is not discoverable at the IP level (invalid IP address, etc.) or HiQnet address level (HiQnet address conflict, etc.) will not be able to report its Container : Position data. In this instance, the Container : Position field will display a "?" to indicate that the field may exist but that the software does not have enough discoverability of the device to determine the value. A blank field or "-" implies the value is null.

12. Locate

The Locate feature allows a device to be easily identified within a network full of HiQnet devices. Clicking in the Locate column for a device will put the corresponding networked device into a Locate state — the Locate icon will be displayed on-screen and something will happen on the device to indicate the Locate state is active (e.g., an LCD or LED will flash, etc.). Clicking an active Locate icon will disable the Locate state for the device. Disabling the Locate state from the device will clear the icon. Devices may be put into a Locate state independently from selection so that more than one device can be located at any one time.

Using HiQnet Audio Architect

Crown CDi DriveCore amplifiers have Digital Signal Processing built in. When using a CDi DriveCore amp, the loudspeaker processing (crossovers, limiters, EQs, and delays) are in the onboard DSP, making discrete rackmount loudspeaker processing devices unnecessary. This drastically reduces setup time, commissioning, rack space, and costs. The CDi DriveCore's internal DSP can be used to perform the following:

• Configure signal flow
• Optimize system gain structure
• Configure DSP settings (set driver levels, crossover bands, delays, equalization, and limiting for your particular speakers)
• Configure output bridging, high Z/low Z operation, and much more

Much of the CDi DriveCore's DSP can be monitored and controlled from the front panel. However, additional control and functionality can be achieved via a networked PC running the HiQnet Audio Architect software. The following sections describe how to start using Audio Architect to configure CDi DriveCore Series amplifiers. For additional information on using Audio Architect, please refer to the Audio Architect help file.

Launching the Audio Architect Software

After launching Audio Architect, a prompt will appear if the connected HiQnet devices are properly configured for the network and discovered (see Figure 29). Checking the "Add discovered devices to the Venue automatically" checkbox can save a step when getting started.

Discovered Devices Devices have been discovered, do you want to add them to the Venue automatically? ✓ Add discovered devices to the Venue automatically □ Automatically navigate to Run Venue mode □ Do not show this window again These settings may be changed in Application Options Close

Figure 29: Discovered Devices prompt

Offline & Online Operation Explained

Audio Architect has two defined modes of operation: Offline and Online. When operating in Offline mode, system setting changes made in Audio Architect will not be reflected in the system hardware devices in real time; offline changes must be sent to the system devices in a second step, at which point device settings will be updated. Conversely, when operating in Online mode, any changes made in Audio Architect will be reflected in the system devices in real time.

When operating in Offline mode, the Offline Design ribbon is presented at the top of the Main Audio Architect window. From this window, discovered devices can be added to the venue by clicking on them in the Devices tab on the left and dragging them into the Room window on the right (see Figure 30).

Drag and drop to add device to venue

Figure 30: Main Audio Architect window

Note that when a device is added to the venue, it is automatically removed from the "Discovered" device list. If the "Add discovered devices to the Venue automatically" checkbox was checked upon launching Audio Architect, as previously mentioned, discovered devices were already added to the Venue and this step is not necessary.

Each device added to the venue will have an IP address listed to the left of the amplifier image and a Name ID to the right (see Figure 31). The Name ID can be edited in the Properties menu at the bottom of the window. The number to the left of the Name ID is the HiQnet Device Address. The green circle indicates that the amplifier has been discovered on the network.

TIP: Double clicking a device image will open the device's Main Control panel (see "Main CDi DriveCore Control Panel" on page 34 for more information).

Going Online

You will have to go online in Audio Architect before any changes can be made to device settings.

To go online:

1. From the Offline Design ribbon at the top of the Main Audio Architect window, click the Go Online button. The Offline Design and Add Devices ribbons will now be replaced with the Online Operate ribbon and, in some cases, the Match Devices ribbon.
2. When going online, the following scenarios are possible:

a. If one or more devices in the venue are not matched AND corresponding devices are available on the network, going online lands in Match Devices mode.

NOTE: Before you can go online with a device, it must be "matched". See "Matching Devices" on page 33 for more information.

b. If all the devices in the venue are matched, going online lands in Synchronize Venue mode. In Synchronize Venue mode, Receive and Send icons will appear for each device in the venue, as well as for a rack if more than one device has been added (see Figure 32). This provides the ability to send/receive data either to/from a single device, or to/from all devices within the rack with a single click.
c. If no devices require matching or synchronization, going online lands in Run Venue mode. In this mode, Audio Architect is online with the devices in the venue and real-time setting changes can be made.

Amplifier Information

The Global Settings panel can be accessed by clicking the Global Settings button from the Main CDi DriveCore Control panel (Figure 35). The Global Settings panel (Figure 36) displays amplifier information such as current firmware version, power supply temperature, channel temperature, and more.

The following functions can also be configured from the Global Settings panel:

1. Output Labels

These fields allow user-defined names to be entered for the analog output channels for reference.

2. Front Panel Lockout

When turned on, the front panel controls will be locked to prevent tampering. The exception is the Power button, which will remain functional.

TIP: The front panel controls can also be locked directly from the front panel, however, if the front panel has been locked from Audio Architect, it must be unlocked from Audio Architect. See "Security/Front Panel Lockout" on page 66 for more information on locking/unlocking the front panel controls from the front panel.

3. Front Panel Blackout Mode

Turns the front panel display on or off.

4. Amp Status Port

Selects whether a 2Hz square wave heartbeat or +5VDC signal is sent to the Amp Status pin on the AUX port — either can be used to remotely determine amp health/status.

5. Mute Input

Determines which output channels will be muted when using GPIO Input 1 (pin 3). By default, a high condition will cause all checked input channels to mute. Checking the Invert checkbox will invert the polarity/functionality, meaning a low condition will cause all checked inputs to mute.

6. Fault Output

Inverts the polarity/functionality of GPIO Output 1 (pin 1). When checked, GPIO Output 1 will indicate an amp fault when in a low state, rather than the default high state. See "System Protection" on page 72 for more information on faults.

7. Preset Recall Input

Loads one of two presets depending on the high/low state of Input 2 (pin 5) on the GPIO port. By default, these values are set to 0, which disables the function.

8. Manual Aux Output

When this button is switched on, GPIO pin 2 (Output 2) will go high; when the button is off the state will be low. This provides a general purpose output which can be used to control many external devices such as relays, indicators, PLC system controllers, or any other 3rd party device with logic control inputs. This button can be controlled from its default location on the Global Settings panel, from a user-created custom control panel, using logic functions in Audio Architect, or from a compatible HiQnet wall controller. The state of this button and the resulting output are stored/recalled along with device presets.

9. Power Modes

Use these settings to turn the APD and ACD power saving modes on or off and adjust the behavior of the ACD feature. See "Power Saving Modes" on page 71 for more information.

For more information on using the GPIO control port, see "Using the GPIO Control Port" on page 69.

Configuring Inputs & Outputs in Audio Architect

Assigning Input Sources in Audio Architect

All channels of the CDi DriveCore signal processing share a single Input Selector panel (shown in Figure 38). From this panel, you can select the audio signal that will be routed to each amplifier channel and adjust the levels entering each channel's DSP chain.

Figure 37: Input button

The Input Selector panel can be accessed by clicking any of the INPUT buttons from the Main CDi DriveCore Control panel (see Figure 37).

1. Levels, Meters, & Clip Indicators

The level faders are used to adjust signal levels entering the DSP chains from the various input sources. The meters in this panel display both peak and RMS levels — the wider left meter shows RMS level and the right meter shows peak level for each channel. The clip indicators light to indicate clipping at the signal point just before the loudspeaker management processing (delays, EQ, crossover, etc.).

2. Input Selector Dropdown Menus

From these dropdown menus, input channel assignments can be selected for each channel. Analog inputs are available for selection in

all CDi DriveCore amp models. Mono summed analog options are also available. Additional BLU link channel options are available in BLU link CDi DriveCore amp models. When assigning BLU link channels, a second dropdown menu will appear, where the desired BLU link channel can be selected, as shown in Figure 38. These BLU link channel assignment dropdown menus provide an easier method for assigning BLU link channels, however, note that BLU link channels can also be assigned from the BLU link Input Channel Assignment window (see Figure 41).

3. Input Labels

These fields allow user-defined names to be entered for the analog input channels, which can be used for reference and added to custom control panels.

4. Input Configuration and Output Configuration Buttons

Clicking the Input Configuration button opens the Input Configuration panel, where input levels and analog gain structure can be adjusted (see "Configuring Inputs" on page 37 for more information). Clicking the Output Configuration button (available only in BLU link amp models) opens the BLU link Output Configuration panel, where the amplifier's BLU link output channels can be configured (see "Configuring BLU link Outputs" on page 38 for more information).

5. Triggered Source Selects Button

Pressing this button will open the Triggered Source Selects panel (see Figure 39). This panel makes it easier to program a BSS Contrio Ethernet wall controller to recall up to four source selection states (Trigger A-D), along with input gain settings and on-screen controller labels. See "Programming BSS Contrio Ethernet Wall Controllers" on page 49 for more information on using this panel and configuring Contrio wall controllers

Using HiQnet Audio Architect

Configuring Inputs

The Input Configuration panel can be accessed by clicking the Input Configuration button from the Input Selector panel (see Figure 38).

The Input Configuration panel (Figure 40) allows you to adjust signal levels entering the amplifier from the various sources. The BLU link CDi DriveCore models will display additional BLU link (Network) inputs.

The meters in this panel display both peak and RMS input levels — the wider left meter shows RMS level and the right meter shows peak level for each channel. Input Mute buttons are available for each channel. Network Signal Status LEDs below each BLU link input channel provide confirmation of BLU link signal presence.

The Gain Mode option is used to set the maximum amount of gain the amplifier will provide. The available options are +26 dBu, +34 dBu, and +37 dBu. Note that changes to this setting will affect all channels.

Clicking the Advanced Settings button opens the Advanced Settings panel, where BLU link sample rate and mastership clock priority can be set. See "Configuring BLU link Clock" on page 38 for more information.

If using one of the BLU link CDi DriveCore models, the Audio Routing button will be available in the Input Configuration panel (Figure 40). Clicking the Audio Routing button opens the BLU Link Input Channel Assignment window (see Figure 41). This is the traditional Audio Architect window used for assigning BLU link channels. From this window, any available BLU link audio streams can be assigned to the CDi DriveCore's inputs. Note that CDI DriveCore amplifiers provide an easier method for assigning BLU link input channels directly from the Input Selector panel (see Figure 38).

Figure 40: Input Configuration panel (BLU link model shown)

Figure 41: BLU Link Input Channel Assignment window

Configuring BLU link Clock

The Advanced Settings panel can be accessed by clicking the Advanced Settings button from either the Input Configuration panel (see Figure 40) or from the Output Configuration panel (see Figure 43). From the Advanced Settings panel, BLU link sample rate and mastership clock priority can be set. This panel also displays clock sync status and BLU link input/output connection status. Input/output errors and corrected errors are also displayed and can be reset from this panel. For more information on these parameters, see "Configuring BLU link Settings" on page 22 and "BLU link Status" on page 62.

Configuring BLU link Outputs

Clicking the Output Configuration button from the Input Selector panel (see Figure 38) opens the BLU link Output Configuration panel (see Figure 43). From this panel, audio source signals can be routed ("on-ramped") back onto the BLU link bus as follows:

- Pre-processed audio from the inputs can be routed to the BLU link bus.

NOTE: The audio from the analog inputs will still pass through the amplifier input gain stage. This means the signals will be affected by the Gain Mode setting and the Input Level faders located in the Input Configuration panel (Figure 40) before being sent out to the BLU link bus.

- Amp output channels can be routed to the BLU link bus.

NOTE: The output audio is bussed from a point at the end of the amp's signal processing chain and includes the Transducer Thermal Limiter. This is effectively analogous to taking the audio from the physical output of the amplifier, which feeds the loudspeaker, and routing it onto the BLU link bus.

To route amplifier audio onto the BLU link bus, select the audio source for each output channel using the Audio Source dropdown menus, then select which BLU link channel to route each signal to using the BLU link Channel dropdown menus.

Configuring Amp Wiring & Output Modes in Audio Architect

The CDi DriveCore amplifiers are very capable and flexible amplifiers. From the Amplifier Mode Settings panel, the following items can be configured:

• Inputs can be cascaded ("Y'ed") to multiple outputs.
• Output pairs can be bridged for mono operation.

- Outputs can be independently configured for Low Z or High Z (70V/100V) operation.

Figure 45: Mode button

The Amplifier Mode Settings panel can be accessed by double-clicking the MODE button from the Main CDi DriveCore Control panel (see Figure 45).

Cascading Inputs

The ability to cascade inputs (or "Y" channels) makes the CDi DriveCore Series amps even more flexible. One input can be used to drive some or all of the amplifier outputs (see Figure 46).

NOTE: By cascading the inputs, the corresponding input DSP functions for individual channels will be removed and only the output DSP functions will be available, as shown in Figure 47.

Configuring Outputs for Bridge Mono Operation

When more output power is required for the application, output channel pairs can be configured for bridge mono operation. This can be configured in the Amplifier Mode Settings panel (see Figure 48).

When selecting the Bridge Mono option for an output pair, only the odd-numbered input channel will need to be wired.

NOTE: When configured for bridge mono operation, only one channel in the channel pair DSP will be available, as shown in

Figure 49.

Configuring Outputs for Low Z/High Z Operation

The CDi DriveCore's output channels can be configured for Low Z or High Z operation. To configure the amplifier for High Z operation, select either the 70V or 100V option (see Figure 50).

NOTE: If an amplifier output channel pair is configured for bridge mono operation and one of the High Z options is selected, the amplifier output will produce 140V or 200V (rather than 70V or 100V).

NOTE: When configured for High Z operation, a 35Hz high-pass filter will automatically be applied to the signal. When configured for Low Z operation, a 10Hz high-pass filter will automatically be applied to the signal.

- Peak Threshold (1 - 200 VPK)

Sets the peak level, in absolute voltage, which the limiter will allow

from the amplifier. In Automatic mode, the Peak Threshold value is automatically determined from the defined RMS threshold and the low pass frequency defined in the crossover.

- Peak Release (0 – 10 seconds)

Sets the release time of the peak limiter. The release time is defined as the time it takes the limiter to increase the output signal by 20dB.

• RMS Threshold (1 – 400 VRMS)

Sets the RMS level, in absolute voltage, which the limiter will allow from the amplifier. The RMS Threshold should be set to correspond to the short term (2 hour) power handling of the transducer or system.

• RMS Release (0 – 10 seconds)

Sets the release time of the RMS limiter. The release time is defined as the time it takes the limiter to increase the output signal by 20dB

• Thermal Voltage (1 - 500V)

Sets the long-term output power limit of the amplifier to what the loudspeaker load can handle without overheating and going into thermal compression. This is based on the AES power/voltage ratings of drivers outlined in the AES2-2012 standard.

• Thermal Response (1 - 600 sec)

Sets the time it takes for the thermal limiter to adjust output voltage. This is based on the AES power/voltage ratings of drivers outlined in the AES2-2012 standard.

- Metering

These meters display levels in dBFS and include Amp Output (peak level on the left meter and RMS level on the right), Gain Reduction (peak, RMS, and total), and Thermal Limiting amount. The Transducer Thermal Limiting indicator lights to indicate the Thermal Threshold has been exceeded.

NOTE: The LevelMax limiters include sidechain EQ for advanced speaker tunings. Sidechain EQ parameters are not user adjustable.

For more information on the LevelMAX limiters and how to set the parameters, see the LevelMAX white paper available at www.crownaudio.com.

About the Transducer Thermal Limiter

The Transducer Thermal Limiter limits the long-term output power of the amplifier to what the loudspeaker load can handle without overheating and going into thermal compression. You can set the voltage level at which the thermal limiter engages, and the thermal response time. Your loudspeaker manufacturer might be able to provide this information.

Programming BSS Contrio Ethernet Wall Controllers

The BSS Audio Soundweb Contrio Ethernet wall controllers can be used to control many of the parameters and functions in a CDi DriveCore amplifier. At the time of this writing, there are four Ethernet Contrio controller models available. Contrio controllers come in black or white, with US and EU versions available (black US models shown).

Balance End Platform End Software Pool and SBS For Closed-All Non-All Standard Base

To program a Contrio Ethernet wall controller:

1. Launch Audio Architect.
2. The Contrio controller must be on the same network as the CDi DriveCore amp and the computer running Audio Architect. If using a DHCP server, the network settings should be automatically configured correctly. If using static IP addressing, use the NetSetter application to configure the Contrio controller's network settings. See "Configuring the Network using NetSetter" on page 25 for more information.
3. If the CDi DriveCore amp and Contrio wall controller are already visible in Audio Architect's Room window, skip to step 5. If they are not visible, select the "Devices" tab in the lower-left corner of the Main Audio Architect window. Any detected HiQnet devices will appear under the "Discovered" menu tree on the left.

Using BLU link

BLU link is a digital audio bus found on the BLU link CDi DriveCore amplifier models. BLU link devices are connected using standard Category 5e or higher cabling. This minimizes cable connections and reduces the amount of cable required, hence, cable cost. BLU link connections carry up to 256 channels of high-resolution digital audio at 48kHz, or 128 channels at 96kHz, both at 24-bit.

BLU link Specifications

• Based on Gigabit Ethernet technology
• Up to 100m over CAT5e cable between each point (>100m using fibre converters)
  • 256 channels at 48kHz
  • 128 channels at 96kHz
  • 24-bit audio resolution
• Bus-like architecture — audio transmitted on a channel is available at all other devices on the bus automatically
• Wired in a loop for redundancy — recovers from a single cable break
• Up to 60 BLU link nodes (devices) can exist in a single BLU link system

BLU link Latency

Path Total Latency (for selected path)
Analog Input to Amplifier Output 1.78ms
BLU link Input to BLU link Output (48kHz) 4	47ms
BLU link Input to BLU link Output (96kHz) 3	57ms

NOTE: Latency through the BLU link/analog mixed paths will be greater than the "Analog Input to Amplifier Output" path but less than the "BLU link Input to BLU link Output" paths.

Making BLU link Connections

On the rear panel of BLU link devices there are two BLU link ports: a BLU link input port and a BLU link output port. Devices are connected together by wiring the output port of the first device to the input port of the next, then repeating for each BLU link device on the bus. If redundancy is required, the last BLU link device on the bus should be connected back to the first. This allows audio to still pass through the BLU link ring when a single BLU link cable is compromised or disconnected.

If ferrites were included with the amplifier, they should be attached to the BLU link cables at the back of the amplifier as shown in Figure 74. If no ferrites were included, they are not required.

NOTE: Only connect BLU link ports to other BLU link ports. Connecting BLU link ports to networking peripherals, such as an Ethernet switch or router, will not work.

See "Assigning Input Sources" on page 14 for information on assigning BLU link input channels.

See "Configuring BLU link Settings" on page 22 for information on assigning BLU link output channels and configuring the BLU link sample rate.

BLU link Port LED Indicators

Each BLU link port has LEDs that indicate the following:

Both Yellow LEDs On

This indicates the device is the BLU link master (meaning it's providing the clock for the entire BLU link system).

The green LEDs light to indicate the port has established a link with the BLU link bus. If there are no cables connected, the green LEDs will not light.

One Yellow LED On

This indicates the device is slaved to the BLU link clock received from the connected device.

The green LEDs light to indicate the port has established a link with the BLU link bus.

No Yellow LEDs On

This indicates the device is not receiving BLU link clock and will not pass audio. This either indicates the IN and OUT ports are swapped (an OUT port is connected to an OUT port and an IN port is connected to an IN port), or there is a mismatch between the BLU link sample rates of the amplifier and the connected device(s).

See "Configuring BLU link Settings" on page 22 for information on configuring the amplifier's BLU link sample rate.

The green LEDs light to indicate the port has established a link with the BLU link bus.

WARNING: Only connect to networks that remain inside the building.

Mastership

The BLU link bus requires one device on the bus to act as master. The master will provide the clock for all other devices on the bus. This means that the whole bus is synchronised to a single audio clock.

NOTE: The BLU link sample rate for all device's on a BLU link bus must be configured to match. By default, the CDi DriveCore amps are configured with the BLU link sample rate set to 96kHz.

In certain cases, it is possible to incorporate devices of more than one Ethernet transport type (i.e., AVB, CobraNet™, or Dante™) connected within the same BLU link system. In other words, if you're careful, you can design a Harman system which actually includes two or more transports. For example, it's possible for a Harman system to have CobraNet audio being converted to BLU link audio (BLU-800 and BLU-320 both have the ability to "bridge" CobraNet to/from BLU link), which is then converted to Dante audio (BLU-806 and BLU-326 both have the ability to "bridge" BLU link to/from Dante). It all depends on a given transport's ability to "slave" (AKA "re-clock") to a clock being generated by a separate transport.

Which transports support "slaving" to the clock of another transport?

Transport Supports Slaving to Another Transport
AVB No
BLU link Yes
CobraNet No
Dante Yes

The previous table has critical implications on system design when combining two or more transports. Any system based on Soundweb London (including Architectural Media Systems) supports the multi-transport combinations shown in the following table.

Combined Transports Clock Master

BLU link + AVB AVB provides the clock

BLU link + CobraNet CobraNet provides the clock

BLU link + Dante Either BLU link or Dante provides the clock

BLU link + Dante + AVB AVB provides the clock

Any multi-transport combination NOT specifically listed in the previous table is not allowed in Soundweb London systems (without being forced to use analog interconnects between transports). For example, BLU link + AVB + CobraNet is NOT allowed, because the AVB and CobraNet networks would each be synced to different clocks — their own.

Mastership is negotiated between all devices on the BLU link bus, and any change to the bus will trigger the negotiation to restart. The following rules determine which device on the BLU link bus will become clock master:

• If there is only one BLU link device connected to CobraNet/AVB then that device is master.
• If there are multiple BLU link devices connected to CobraNet/AVB, then they compare master priorities.
• If there are multiple BLU link devices on CobraNet/AVB with the same highest priority, then they use MAC address to decide which is master.
• If there are no BLU link devices connected to CobraNet/AVB, then they first compare master priorities. Next, if the priorities are the same, they compare MAC addresses.

Fault Tolerance

When the last BLU link device in a system is connected back to the first, the BLU link bus is capable of a degree of fault tolerance since each device receives the same audio from two other devices. If a single cable connection is broken, the devices which are no longer connected will detect the cable break: one device will detect that its BLU link in port is disconnected and the other will detect that its out port is disconnected. The devices will then reroute the audio so that it can again pass through the bus.

NOTE: When the cable is broken, the audio will take longer to reach its destination. This added delay is not compensated for in any way, but is a side-effect of the way the fault tolerance system functions.

Device Presets

Device presets allow configuration, DSP, channel assignment, gains, as well as other settings to be stored for later recall. A device preset can be used to configure the amp for a specific application and speaker model. For example, you might use one device preset that optimizes the amp's DSP for a JBL bi-amplified speaker setting. Or, you might use a device preset that sets up the DSP for a stereo pair of loudspeakers of your choice. Subtle changes can also be made between device presets, such as a change of input channel assignments. Device presets can be stored within the amplifier or backed up to a PC using Audio Architect.

Preset 1 is the factory default device preset and cannot be overwritten. It sets up the amplifier for pass-thru operation with no DSP features enabled. Presets 2-20 are user device presets and can be overwritten.

The following bullets outline which settings are stored to device presets and which are not:

Using the GPIO Control Port

CDi DriveCore amplifiers come with a 2-in, 2-out General Purpose In/Out (GPIO) control port in the form of a block connector. The Control port has multiple uses which include fault status reporting, device preset selection, output muting, and more. Control ports are configured using the Audio Architect software.

GPIO Pinout, Specification, Use, & Configuration

GPIO/AUX 8 7 6 5 4 3 2 1 SLEEP AMP STATUS IN +3.3V IN OUT

PIN 1 (Output 1): 0VDC to +3.3VDC output. Output impedance = 1KΩ pullup to +3.3V. This pin is used for fault reporting. If a fault occurs in the amplifier, this pin will change from a low/false state to a high/true state. Polarity can be inverted when reversed functionality is required. See "Amplifier Information" on page 35 for information on inverting this output.

PIN 2 (Output 2): 0VDC to +3.3VDC output. Output impedance = 1KΩ pullup to +3.3V. This pin is used by Audio Architect and compatible HiQnet wall controllers for generic output control functions. The functionality of this output is tied to the Manual Aux Output button in the Global Settings panel in Audio Architect. See "Amplifier Information" on page 35 for more information on the Manual Aux Output button.

PIN 3 (Input 1): OVDC to +3.3VDC input. Logic = TTL thresholds. Analog = full scale 0-3.3V. Input impedance >20KΩ. This pin is used to trigger input mutes. By default, a high/true state at the input will trigger the mutes. Polarity can be inverted when reversed functionality is required. Which input channels are muted can be programmed from the Global Settings panel in Audio Architect. See "Amplifier Information" on page 35 for more information on configuring this input.

PIN 4 (3.3V): +3.3VDC output. LIMIT = 30mA. Output impedance = 100Ω to +3.3V. This pin provides the power source to drive the GPIO inputs. For example, a simple switch between this pin and pin 3 (Input 1) will mute/un-mute the designated input channels (a closed switch connects the 3.3V for high/true condition, an open switch allows the pin to float low for false condition).

PIN 5 (Input 2): OVDC to +3.3VDC input. Logic = TTL thresholds. Analog = full scale 0-3.3V. Input impedance > 20KΩ. This pin is used to trigger preset changes between two stored presets depending on high/low state. Which presets are triggered can be configured from the Global Settings panel in Audio Architect. See "Amplifier Information" on page 35 for more information on configuring this input port.

PIN 6 (GND): Provides the ground potential for GPIO outputs and the AUX port.

Using the AUX Port

The AUX port can be used for basic monitoring of the amplifier and for remote standby (sleep). The port is shared with the GPIO using an 8-pin block connector, with pin 6 used as ground.

Sleep

The amplifier can be put to sleep by connecting pins 6 and 8 together on the AUX port. When applying this connection, the amplifier will shut down and remain asleep until the connection between pins 6 and 8 is opened. When the connection between pins 6 and 8 is open, the amplifier will revert to its last configuration and begin to output audio within \~15 seconds. Network communication will be re-established once the network interface card boots. While the amplifier is asleep, the front panel POWER button is disabled and, if pressed, the blue power indicator will blink briefly to indicate the device is asleep.

GPIO/AUX 8 7 6 5 4 3 2 1 SLEEP AMP STATUS IN +3.3V IN OUT

Sleep Open

GPIO/AUX 8 7 6 5 4 3 2 1 SLEEP AMP STATUS IN IN OUT

Amp Status

Amp Status can be used for basic monitoring of the amplifier. Monitoring of the amplifier can determine if the amplifier is operating within optimal parameters, or if the amplifier has been shut off or is in fault. Between pins 6 and 7, there will be either a +5VDC potential or a 2Hz square wave (heart beat). This option can be set from the Global Settings panel in Audio Architect, see "Amplifier Information" on page 35.

Power Saving Modes

The ACD and APD power saving modes allow the CDi DriveCore amplifiers to conserve power consumption during periods of inactivity. The ACD and APD features are enabled by default from the factory.

Auto Channel Disable (ACD)

The CDi DriveCore's individual amplifier channels will automatically disable after a period of channel inactivity. This will occur 30 minutes after audio is no longer present at the output of the DSP for a given channel. A channel will re-enable within 0.5 seconds of audio being sensed at the output of the DSP unless the amplifier has entered Auto Power Down (APD) mode.

NOTE: The ACD feature can be disabled or adjusted from the front panel (see "Power Modes" on page 67) or from Audio Artchitect (see "Amplifier Information" on page 35). Note that ACD will be re-enabled if the amplifier is factory reset or the default preset is loaded.

Auto Power Down (APD)

The APD feature allows a CDi DriveCore amplifier to automatically power down after a period of audio and network inactivity. The amplifier will enter APD mode 30 minutes after all of the following conditions are met:

• There is no signal level detected above approximately -50 dBu at any of the analog inputs
• There is no activity detected on the BLU link network (BLU link CDi DriveCore models only)
  • The signal generator is not active
  • There is no activity detected on the data network

Once the amplifier has entered APD mode, it will exit APD mode if one of the following conditions is met:

• The POWER button is pressed (the sleep pin on the Aux port must also be open (not active))
• Signal level is detected at any of the analog inputs (the sleep pin on the Aux port must also be open (not active))

The amplifier will take approximately 30 seconds to fully recover from APD mode.

NOTE: The APD timer setting is defaulted to 30 minutes from the factory. This timer setting is user adjustable, but it is not available from any preconfigured panels in Audio Architect or from the amplifier's front panel user interface. To access the APD timer setting, the "AmAPDTimeoutSec" SV (located under [0x1]>AM3 in the Venue Explorer tree menu) must be added to a custom panel. Once the desired SV has been added to the custom panel, go online with the amplifier, run the custom panel, then adjust the setting. See the Audio Architect help file for information on using custom panels in Audio Architect. APD can be disabled from the front panel (see "Power Modes" on page 67) or from Audio Architect (see "Amplifier Information" on page 35). Note that APD will be re-enabled if the amplifier is factory reset or the default preset is loaded.

NOTE: 2-channel CDi DriveCore amplifiers manufactured before a certain date are not compatible with the APD feature. For more information, please contact Crown Technical Support.

System Protection

Faults

The amplifier will enter a fault state if it senses an unsafe condition. This protection is for both internal and external faults. In addition, be sure that the load connected to the amplifier is within the 2-16 Ohm limit (4-16 Ohm in Bridge Mono mode). If wiring and load are verified as correct and the fault condition persists, see "Service" on page 88 for servicing information.

The following faults are possible:

Fault Fault Type Description
HF Detect Channel Excessive high frequency signal content has been sensed at the output of the amplifier.
DCLF Channel Excessive DC or low frequency signal content has been sensed at the output of the amplifier.
Short Circuit Detect Channel A short is detected at the output of the amplifier.
Thermal Channel/Power Supply		An amp channel and/or the power supply has exceeded the maximum acceptable temperature threshold.
High Voltage Rail Power Supply		The power supply's high voltage rails are no longer within a safe operating range for the amplifier or other components attached.
Low Voltage Rail Power Supply		The power supply's low voltage rails are no longer within a safe operating range for the amplifier or other components attached.
AC Mains Power Supply	The AC mains have reached an unsafe level.

Thermal Limit

If the amplifier power supply and/or any channels become too hot for safe operation, a thermal fault will occur. If a channel's temperature reaches 80^ Celsius, a message will appear in the front panel display to indicate the onset of audio compression. The amplifier will continue to run in this state until either the temperature is reduced to a safe operating range, or if the temperature continues to rise, the channel will shut off to protect itself above 100^ Celsius. The amplifier will exit the thermal fault state only when the temperature drops back below the thermal limit.

NOTE: If the thermal limit is exceeded while the front panel LCD is asleep, the display will wake up to indicate that thermal limiting is occurring.

Auto-Insertion High-Pass Filters

A 35Hz, 24dB/Octave Butterworth high-pass filter is inserted automatically when a channel is configured for High Z operation. A 10Hz, 24dB/Octave Butterworth high-pass filter is inserted automatically when a channel is configured for Low Z operation.

AC Under/Over-Voltage Protection

If the AC line voltage drops below 10% or rises above 10% of the nominal operating voltage of the amplifier, the amplifier's power supply will turn off and the blue Power LED will flash. The amplifier will turn back on when the AC line voltage returns to safe operating levels.

Fan-Cooled Chassis

CDi DriveCore Series amplifiers are cooled by quiet, variable-speed fans. Maximum fan noise level of the CDi DriveCore amplifier is 51dBA. The fans will pull air from the front of the amplifier to the rear.

The following fault conditions cause the fan to turn on full speed:

• High frequency fault (excessive high frequency signal content has been sensed at the output of the amplifier)
  • Thermal fault (excessive power supply or channel temperature is detected)

NOTE: After a fault, the fan will remain on at full speed until the fault is cleared.

Universal Switching Power Supply

The CDi DriveCore Series amplifiers incorporate a switching power supply designed for extremely high efficiency and high output power. The supply includes Power Factor Correction (PFC) and a Series Resonant Converter (SRC), and accepts AC supply voltages from \~100V to \~240V. Microprocessor-controlled diagnostic and control capabilities both optimize performance and enhance long-term reliability.

CONDITION: When pressing the Power button, power won't turn on and Power indicator flashes blue briefly.

POSSIBLE REASON:

- The amplifier is asleep via the Aux port (contact closure) circuit. See "Using the AUX Port" on page 70 for more information.

CONDITION: Thermal fault is indicated in the display.

POSSIBLE REASON:

- The amplifier is becoming too hot for safe operation. Allow amplifier to cool. Check for loads less than 2Ω and for excessive input levels. Check for proper ventilation and proper output mode (2/4/8Ω, 70V, 100V) setting. See "Proper Cooling" on page 2 for information on rack mounting and cooling. See "System Protection" on page 72 for detailed information on thermal limits. See "Configuring Output Modes" on page 15 for information on configuring the output mode.

CONDITION: Some other fault is indicated in the display.

POSSIBLE REASON:

- There are a number of conditions that result in a fault error being displayed: the operating temperature exceeds 100°C, excessive high or low frequencies are detected at the output, or an output short circuit is detected. These conditions should all be checked and attempted to be resolved before the amp is shipped back for service. See "System Protection" on page 72 for more information on these protection features.

CONDITION: Distorted sound.

POSSIBLE REASON:

- Load is wired incorrectly or Dual/Bridge mode is configured incorrectly — both should be verified. See "Wiring Output Connectors" on page 7 and "Configuring Outputs for Bridge Mono Operation" on page 40.

- Input is overloaded by a signal level that is too high. Turn down the amplifier input level controls, or turn down the output of the source signal until the Clip LED goes out.

NOTE: If the signal sounds distorted even though the Clip LED is off, the signal may be distorted before it reaches the amplifier input. Check gain staging and output levels of the mixer or preamp.

CONDITION: No sound, even though the Power LED is lit blue and the level meters indicate the amp is receiving an input signal.

POSSIBLE REASON:

• Speaker not connected. Power off the amplifier, disconnect the AC power cord, then verify speaker connection.
• Open circuit due to speaker failure. From the front panel display, determine which channel has the short. Power down the amplifier then disconnect the AC power cable. Remove the shorted load from the channel (and possibly attached cables) and have it checked by a qualified technician. Reconnect the power cord and power up the amplifier. If the shorted condition remains after the load is removed, the unit should serviced. See "Service" on page 88.

CONDITION: No input signal. Input signal indicator is not lighting, even though audio is being sent to the amplifier's input and the amp is powered on (blue Power indicator lit).

POSSIBLE REASON:

• Input signal level is very low. Double check the gain structure of the system and ensure that the amplifier's input trim levels are set accordingly.
• Input routing is not configured correctly for application. See "Assigning Input Sources" on page 14.

Factory Reset

The Factory Reset allows a CDi DriveCore amplifier to be reverted back to its factory default state. When initiated, the Factory Reset will perform the following tasks:

• Erase all user presets (this includes all user DSP and configuration settings)
• Reset all system settings
• Reset all BLU link settings (applicable to BLU link CDi DriveCore models only)

To perform the Factory Reset procedure:

Warning! All user presets will be permanently deleted and all settings reverted back to their factory default state. This process is irreversible. If you have any user presets you wish to keep, they should be backed up using Audio Architect before performing the Factory Reset. See "Managing Device & Preset Files" on page 47 for more information.

1. Power off the amplifier by pressing and holding the Power button for 2 seconds.
2. Press and hold the CH1 and CH2 SELECT buttons while powering on the amp. Continue to hold these buttons until the LCD reads: "Press MENU to restore Factory Settings or any other button to exit". Now release the SELECT buttons.
3. Press and release the MENU button to start the Factory Reset procedure (pressing any other button will abort the Factory Reset procedure and the amp will boot up normally).
4. Once the Factory Reset procedure begins, the LCD will display the message: "Restoring factory defaults!" and when complete, the device will boot up normally.

Warranty (United States Only)

SUMMARY OF WARRANTY

Crown International, 1718 West Mishawaka Road, Elkhart, Indiana 46517-4095 U.S.A. warrants to you, the ORIGINAL PURCHASER and ANY SUBSEQUENT OWNER of each NEW Crown product, for three years from the date of purchase by the original purchaser (the "warranty period") that the new Crown product is free of defects in materials and workmanship. We further warrant the new Crown product regardless of the reason for failure, except as excluded in this Warranty.

* Warranty is only valid within the United States of America. For information on Warranty outside of the U.S.A, please contact your local distributor.

ITEMS EXCLUDED FROM THIS CROWN WARRANTY

This Crown Warranty is in effect only for failure of a new Crown product which occurred within the Warranty Period. It does not cover any product which has been damaged because of any intentional misuse, accident, negligence, or loss which is covered under any of your insurance contracts. This Crown Warranty also does not extend to the new Crown product if the serial number has been defaced, altered, or removed.

WHAT THE WARRANTOR WILL DO

We will remedy any defect, regardless of the reason for failure (except as excluded), by repair, replacement, or refund. We may not elect refund unless you agree, or unless we are unable to provide replacement, and repair is not practical or cannot be timely made. If a refund is elected, then you must make the defective or malfunctioning product available to us free and clear of all liens or other encumbrances. The refund will be equal to the actual purchase price, not including interest, insurance, closing costs, and other finance charges less a reasonable depreciation on the product from the date of original purchase. Warranty work can only be performed at our authorized service centers or at the factory. Warranty work for some products can only be performed at our factory. We will remedy the defect and ship the product from the service center or our factory within a reasonable time after receipt of the defective product at our authorized service center or our factory. All expenses in remedying the defect, including surface shipping costs in the United States, will be borne by us. (You must bear the expense of shipping the product between any foreign country and the port of entry in the United States including the return shipment, and all taxes, duties, and other customs fees for such foreign shipments.)

HOW TO OBTAIN WARRANTY SERVICE

You must notify us of your need for warranty service within the warranty period. All components must be shipped in a factory pack, which, if needed, may be obtained from us free of charge. Corrective action will be taken within a reasonable time of the date of receipt of the defective product by us or our authorized service center. If the repairs made by us or our authorized service center are not satisfactory, notify us or our authorized service center immediately.

DISCLAIMER OF CONSEQUENTIAL AND INCIDENTAL DAMAGES

YOU ARE NOT ENTITLED TO RECOVER FROM US ANY INCIDENTAL DAMAGES RESULTING FROM ANY DEFECT IN THE NEW CROWN PRODUCT. THIS INCLUDES ANY DAMAGE TO ANOTHER PRODUCT OR PRODUCTS RESULTING FROM SUCH A DEFECT. SOME STATES DO NOT ALLOW THE EXCLUSION OR LIMITATIONS OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE LIMITATION OR EXCLUSION MAY NOT APPLY TO YOU.

WARRANTY ALTERATIONS

Service

Crown products are quality units that rarely require servicing. Before returning your unit for servicing, please contact Crown Technical Support to verify the need for servicing.

Warranty is only valid within the country in which the product was purchased.

This unit has very sophisticated circuitry which should only be serviced by a fully trained technician. This is one reason why each unit bears the following label:

CAUTION: To prevent electric shock, do not remove covers. No user serviceable parts inside. Refer servicing to a qualified technician.

Complete the Service Return Authorization form in the back of this manual, when returning a Crown product to the factory or authorized service center. The form must be included with your product inside the box or in a packing slip envelope securely attached to the outside of the shipping carton. Do not send this form separately.

Worldwide Service

Service may be obtained from an authorized service center (contact your local Crown/Amcron representative or our office for a list of authorized service centers). To obtain service, simply present the bill of sale as proof of purchase along with the defective unit to an authorized service center. They will handle the necessary paperwork and repair.

Remember to transport your unit in the original factory pack.

US and Canada Service

Service may be obtained in one of two ways: from an authorized service center or from the factory. You may choose either. It is important that you have your copy of the bill of sale as your proof of purchase.

Service at a US or Canada Service Center

This method usually saves the most time and effort. Simply present your bill of sale along with the defective unit to an authorized service center to obtain service. They will handle the necessary paperwork and repair. Remember to transport the unit in the original factory pack. A list of authorized service centers in your area can be obtained from Crown Factory Service, or online from www.crownaudio.com/en/support/service_lookup

Factory Service

Crown accepts no responsibility for non-serviceable product that is sent to us for factory repair. It is the owner's responsibility to ensure that their product is serviceable prior to sending it to the factory.

A Service Return Authorization (SRA) is required for product being sent to the factory for repair. An SRA can be completed online at www.crownaudio.com/support/rma. If you do not have access to the web, please call Customer Service at 574.294.8200 or 800.342.6939 extension 8205 in North America, Puerto Rico and the Virgin Islands only.

For warranty service, we will pay for ground shipping both ways in the United States. Contact Customer Service to obtain prepaid shipping labels prior to sending the unit. Or, if you prefer, you may prepay the cost of shipping, and HARMAN will reimburse you. Send copies of the shipping receipts to HARMAN to receive reimbursement.

Your repaired unit will be returned via UPS ground. Please contact us if other arrangements are required.

GNU General Public License Version 2

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.

51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification follow.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

1. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to

the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

1. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:

a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

1. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.

If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source

code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.

1. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
2. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.
3. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.
4. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

1. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
2. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.

1. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.

NO WARRANTY

1. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
2. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE

PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

one line to give the program's name and an idea of what it does.

Copyright (C) yyyy name of author

This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.

You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this when it starts in an interactive mode:

Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names:

Yoyodyne, Inc., hereby disclaims all copyright

interest in the program `Gnomovision'

(which makes passes at compilers) written

by James Hacker.

This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.

Preamble

The GNU General Public License is a free, copyleft license for software and other kinds of works.

The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.

To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.

For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.

Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.

Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.

The precise terms and conditions for copying, distribution and modification follow.

TERMS AND CONDITIONS

1. Definitions.

"This License" refers to version 3 of the GNU General Public License.

"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.

"The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations.

To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a “modified version” of the earlier work or a work “based on” the earlier work.

A "covered work" means either the unmodified Program or a work based on the Program.

To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.

To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.

An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.

1. Source Code.

The “source code” for a work means the preferred form of the work for making modifications to it. “Object code” means any non-source form of a work.

A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.

The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A “Major Component”, in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.

The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.

The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.

The Corresponding Source for a work in source code form is that same work.

2. Basic Permissions.

All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.

You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.

Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.

3. Protecting Users' Legal Rights From Anti-Circumvention Law.

No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.

When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.

4. Conveying Verbatim Copies.

You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.

You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.

5. Conveying Modified Source Versions.

You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:

a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices".
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.

A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.

6. Conveying Non-Source Forms.

You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:

a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the

Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.

e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.

A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.

A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, “normally used” refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.

"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.

If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).

The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.

Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.

7. Additional Terms.

"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.

When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.

Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:

a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.

All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.

If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.

Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.

8. Termination.

You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).

However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.

Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.

Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.

9. Acceptance Not Required for Having Copies.

You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.

10. Automatic Licensing of Downstream Recipients.

Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.

An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.

You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.

11. Patents.

A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's “contributor version”.

A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.

Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.

In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To “grant” such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.

If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.

If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.

A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.

Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.

12. No Surrender of Others' Freedom.

If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.

13. Use with the GNU Affero General Public License.

Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.

14. Revised Versions of this License.

The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.

If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.

Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder

as a result of your choosing to follow a later version.

15. Disclaimer of Warranty.

THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

16. Limitation of Liability.

IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

17. Interpretation of Sections 15 and 16.

If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

Copyright (C)

This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.

You should have received a copy of the GNU General Public License along with this program. If not, see http://www.gnu.org/licenses/.

Also add information on how to contact you by electronic and paper mail.

If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode:

Copyright (C)

This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'.

This is free software, and you are welcome to redistribute it

under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box".

You should also get your employer (if you work as a programmer) or school, if any, to sign a “copyright disclaimer” for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see http://www.gnu.org/licenses/.

The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read http://www.gnu.org/philosophy/why-not-lgpl.html.
