Note: DCi DA 8|600 (8-channel) back panel shown. 4-channel model has same features but half as many input/output channels.

Hardware Setup and Configuration

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 3 shows connector pin assignments for balanced wiring and Figure 4 shows connector pin assignments for unbalanced wiring. Note that for bridged operation, only the odd-numbered input channels (1,3,5,7) should be wired for each bridged pair.

For Dante audio connections, standard Category 5e or 6 Ethernet cabling should be used for Gigabit networks. Category 5 cabling can be used for 100Mbps network connections. Primary and Secondary Dante ports are provided; Dante audio traffic is duplicated to both of these ports. The Secondary port can be connected to a second network switch for redundant operation in the event the Primary cable connection or switch is compromised.

INPUT SHEILD SOURCE

Figure 3: Balanced wiring

SHIELD SOURCE INPUT

Figure 4: Unbalanced wiring

Wiring Output Connectors

IMPORTANT: The amplifier output mode (Low Z, High Z) should be properly configured for the application before connecting the speakers. By default, all outputs are configured for Low Z operation. See "Hi-Z/Low-Z" on page 15 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 "DCi DA Specifications" on page 47 for supported load specifications.
NOTE: Crown has designed an output cover that does not need to be removed to connect the output wiring.
Crown recommends using the included spade connectors and two 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 5). 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, 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 3 WIRING OUTPUT

Figure 5: 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 18.

Connecting Network Cables

When making connections to the control network and Dante ports, the included ferrites should be attached to the network and Dante cables at the back of the amplifier as shown in Figure 6. Both a small and large ferrite should be attached to each cable as shown.

Connecting to AC Mains

Connect your amplifier to the AC mains power source (power outlet) using the supplied AC power cord set. First, connect the IEC end of the cord set to the IEC connector on the amplifier; then, plug the other end of the cord set to the AC mains.

WARNING: The third prong of this 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. If the AC line voltage varies out of an acceptable range, the amplifier's power supply turns off and the blue Power LED flashes. The amplifier will turn back on when the AC line voltage returns to safe operating levels.

DriveCore Install DA amplifiers utilize a universal power supply. The AC voltage requirements are 100V-240V\~, 50/60Hz (±10%). If the voltage exceeds these requirements, the Power LED will flash and the amplifier will stop passing audio until the voltage is within the requirements.

Startup Procedure

When first turning on your amplifier:

1. Turn down the level of your audio source.

2. Turn on the "Power" switch. The Power indicator should light.

3. Turn down the amplifier levels in Audio Architect, see "Channel Levels and Mutes" on page 35

4. Turn up the level of your audio source to an optimum level. Ensure that at no point in the signal chain is the signal being clipped in any way.

5. In Audio Architect, turn up the amplifier levels to the desired level.

ETHERNET300MACT PRIMARYSEC CHANNEL

Figure 6: Ferrites attached to network cables

IMPORTANT: Before making any wiring or installation changes, turn off the amplifier and disconnect the power cord.

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 4. 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.

Software Setup

Setup and configuration of the DriveCore Install DA Series amplifiers can be completed through HiQnet Audio Architect™. The amplifier should be connected to a TCP/IP network via the Ethernet connection on the back of the amplifier. Note that the Dante digital audio transport connectors cannot be used for control and monitoring of the amplifier.

To quickly configure your DriveCore Install DA amplifier, connect all of the amplifiers and configuration computer to the same network. For more information on network configuration, please visit http://audioarchitect.harmanpro.com. In the following example, we will only show amplifiers.

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 ADD DEVICES tab on the left hand tree menu. If the devices are not found, then the network may not be configured correctly. See Figure 7.

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, Dante 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.

Offline/Online Operation Explained

Audio Architect has two define modes of operation: Offline and Online. Offline operation allows the system to be configured without real time changes to the system. In this mode, changes have to be sent to the edited device. In Online mode, changes to amplifiers are made real time.

When Audio Architect first opens, the Offline Design Tab is the ribbon presented, and the Device Toolbox appears on the left and an empty Properties window is at the bottom. The Add Devices box is highlighted. When going Online, it may be necessary to Match Devices and/or Synchronize Venue.

- Editing

Clicking the Undo button will undo the last change made and revert back to the previous state. Clicking the Redo button will redo the last action that was undone.

• Show

Any checked items in this section will be displayed alongside the appropriate devices in the Main Audio Architect window. The available items include Device Names, Rack/Array Names, HiQnet Addresses, IP Addresses, Matched Indicator, and Unmatched Indicator.

When going Online, the following options are possible:

• 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.
- If all the devices in the Venue are matched, going online lands in Synchronize Venue mode. In Synchronize Venue mode, the user is given the option to either Send data from Audio Architect to the device or Receive data from the device to Audio Architect.
- If no devices require to be synced, going online lands in Run Venue mode.

Each amplifier can be dragged into the room window. Each device will have an IP address listed on the left of the amplifier and a Name ID on the right of the amplifier. The Name ID can be edited in the properties menu at the bottom of the window. The number to the left of Name ID is the HiQnet Device Address. The green circle only indicates that the amplifier has been discovered on the network.

The small box located below the rack allows quick access to amplifier factory panels. These panels include the following items:

• Factory Master Panels
• Monitor Panels
• Meter Panels
  • Level and Mute Panels

NOTE: When a device is added to the window, it is automatically removed from the "Discovered" section.

Figure 15: Configuration panel (4-channel amp model shown)
Figure 15 (above) shows the Configuration panel for a 4-channel DriveCore Install DA amplifier. The 8-channel amplifier Configuration panels have the same feature set. The DriveCore Install DA amplifier includes Digital Signal Processing (DSP), multiple input/output routing options, and a comprehensive diagnostics feature set. All of these features can be adjusted from the Configuration panel.

The DriveCore Install DA amplifiers are very capable and flexible amplifiers. In the Amplifier Mode Setting window (see Figure 16), the following items can be adjusted.

• Hi-Z/Low-Z on an individual channel basis.
- 70Vrms or 100Vrms operation
- Any analog input can be sent to any amplifier output
- Mono Bridge Output - Output pairs can be bridged for mono operation

Hi-Z/Low-Z

The DriveCore Install DA amplifiers are capable of High Z and Low Z outputs. Each individual channel is capable of Hi-Z or Low-Z operation. To select Hi-Z or Low-Z operation, double click on the mode button, the Amplifier Mode Setting Window will open (see Figure 16).

Application Examples

Dual Mode Low-Z (8Ω, 4Ω or 2Ω) Output Operation

Typical input and output wiring, along with Audio Architect software settings are shown in Figure 21 and Figure 22.

INPUTS: Connect the input with wiring in place for each channel. If the same signal is to drive both outputs of a channel pair ("mono"), the input signal can be sent to adjacent amplifier channels.

OUTPUTS: Maintain proper polarity (+/-) on output connectors. Connect the Channel 1 speaker's positive (+) lead to amplifier Channel 1 positive terminal; repeat for negative (-). Repeat Channel 2 wiring as for Channel 1, and for any subsequent channel pairs on multichannel models. Refer "Wiring Output Connectors" on page 4 for output connector terminal assignments.

DANTE: When connecting via Dante, two Dante-equipped devices can be connected directly together using the Primary Dante ports. If connecting more than two Dante devices, the Primary ports of each device should be connected to a network switch (this is a referred to as a "star" network topology).

100Mbps network switches and Category 5 cabling can be used for smaller Dante networks where smaller channel counts and/or lower sample rates are used. For optimum performance and improved reliability, a Gigabit network and Category 5e or Category 6 cabling should be used. Visit the Audinate website for more information.

To provide fault protection when using Dante, connect the Secondary ports of all Dante devices to a secondary (separate) network switch. If any "primary" cable connections or the "primary" switch fail, the "secondary" Dante network will automatically take over.

For further information on Dante, refer to "Dante" on page 28.

DANTE: When connecting via Dante, two Dante-equipped devices can be connected directly together using the Primary Dante ports. If connecting more

than two Dante devices, the Primary ports of each device should be connected to a network switch (this is a referred to as a "star" network topology).

100Mbps network switches and Category 5 cabling can be used for smaller Dante networks where smaller channel counts and/or lower sample rates are used. For optimum performance and improved reliability, a Gigabit network and Category 5e or Category 6 cabling should be used. Visit the Audinate website for more information.

To provide fault protection when using Dante, connect the Secondary ports of all Dante devices to a secondary (separate) network switch. If any "primary" cable connections or the "primary" switch fail, the "secondary" Dante network will automatically take over.

For further information on Dante, refer to "Dante" on page 28.

General Purpose In/Out Control Port

DriveCore Install DA Series amplifiers come with a 2-in, 2-out General Purpose In/Out (GPIO) control port in the form of a 6 position RJ-11 connector. The Control Port has multiple functions and uses which include preset selection and gain control, among others.

Hardware Specification

Inputs are capable of either binary or analog control of a State Variable (SV) within the amplifier. Outputs are binary only that represent an SV of the amplifier. Additionally, outputs can be controlled independently (on/off, polarity) via the software.

PIN 1: Output 1. 0VDC to +3.3VDC output. Output impedance = 1KΩ pullup to +3.3V.

PIN 2: Output 2. 0VDC to +3.3VDC output. Output impedance = 1KΩ pullup to +3.3V.

PIN 3: Input 1. 0VDC to +3.3VDC input. Logic = TTL thresholds. Analog = full scale 0-3.3V. Input impedance >20KΩ.

PIN 4: +3.3VDC output. ILIMIT = 30mA. Output impedance = 100Ω to +3.3V.

PIN 5: Input 2. 0VDC to +3.3VDC input. Logic = TTL thresholds. Analog = full scale 0-3.3V. Input impedance >20KΩ.

PIN 6: GND.

Configuring the Control Port Inputs

2 inputs: Can be variable (connect to potentiometer), binary (connect to switch), or multilevel connect to rotary switch and voltage steps.

• Audio Architect is used to assign up to 40 SV's to each input
- An input mode is selected

SET - Sets the assigned SV(s) to a specific value

VARY - Continuously varies the assigned SV(s) by a specified value, typically a volume pot application.

PRESET - Recalls the max preset in one state (high) and the min preset in the other state (low)

BUMP - Similar to vary but implemented with a button instead of a pot. A high level will bump the assigned SV(s) by a specific value.

AUTOBUMP - Similar to bump, but will continue to bump the assigned SV(s) value as long as the input state is changed.

Right click on a DCi DA in the venue. Select "Configure Control Ports". A new tab labeled "(amplifier name) – Control Ports" will open.

Software Parameters

High Limit – Available only on input, and only for parameters in "Analog Input" mode. This field determines the value that the selected assigned parameter will assume when the control port input is at the maximum end of its range.

Input - selects between control port inputs, labeled 1 and 2.

Low Limit – Available only on input, and only for parameters in “Analog Input” mode. This field determines the value that the selected assigned parameter will assume when the control port input is at the minimum end of its range.

Mode - For the control port input, the Mode field determines how the assigned parameters will be controlled. For the control port output, the Mode field determines the conditions under which the output status will change.

Off Value – Available only on input, and only for parameters in "Direct Action" mode. Determines what the value of the selected assigned parameter will be when the control port input is logic "Low".

On Value – Available only on input, and only for parameters in "Direct Action" mode. Determines what the value of the selected assigned parameter will be when the control port input is logic "High".

Output - Selects between control port outputs, labeled 1 and 2.

Output Polarity – Enables selection between "Normal" and "Inverted".

Parameter Assignment – List of parameters that are currently assigned to a given control port input

Once an SV has been added, its type will determine which MODE options become available. If a binary SV has been assigned, only the "Direct Action" mode is selectable, and the "ON VALUE" and "OFF VALUE" parameters can be toggled as desired. However, if a non-binary SV is added, the "Analog Input" Mode becomes available. In this mode, the ON and OFF VALUE fields are unused, and the "HIGH LIMIT" and "LOW LIMIT" fields appear and become accessible. The LIMIT fields allow control of an SV over a specified range.

Additional state variables can be added to a given control port input by selecting the SV and dragging on top of a previously assigned row of the desired input. However, once an SV has been assigned and the MODE has been set, any subsequent SV that is added must function in the same MODE. Up to 40 SV's can be assigned to a given input.

Configuring the Control Port Outputs

2 outputs: Binary only.

• There is a polarity control on each output so that it may function as active-high or active-low
• Output Mode 1 - Manual: Controlled directly by the output enable button

• Output Mode 2 - Report Errors: Active when any enabled error is reported. The indicator will stay on for up to 60 seconds after the error is cleared. Errors include:

Load Supervision
AC Line Voltage is out of range
Hardware Protection (faults)
Over temperature (any channel or power supply)
Amp output clipping
Processing output clipping (off by default)
Analog Input clipping (off by default) 

• Output Mode 3 - Report online status: Active when HiQnet connection is lost. The length of time to wait for a time out is user adjustable, default = 60 seconds

The Control Port output configuration options can be found directly below those for the input. No parameters can be assigned to the outputs. Instead, there are three modes available: Manual, Report Errors, and Report Online Status. Manual mode enables direct control over the selected output. In "Report Errors" mode, the output status will change if any errors are reported to the network, such as clip errors, temperature errors, line voltage errors, etc. Finally, in "Report Online Status" mode, the output status will change if no network communication is detected for at least 60 seconds. The control port output does not turn off right away when reporting errors or online status. There are several reasons for this. The online status does not change quickly, it can take up to 60 seconds to drop offline or to recover. In these modes, the output is intended to be used with devices such as a backup amp switcher or an electro-mechanical system. We want to prevent this output from toggling on/off quickly. It may take the output up to 90 seconds to recover (i.e. switch states) from an error or loss of connection.

Aux Port/Sleep/Amp Status

AUX Port

The AUX port can be used for basic monitoring of the amplifier and for remote standby. The port is a 3 pin block connector with pin-2 used as ground.

Sleep

The amplifier can be put to sleep by connecting pins 1 and 2 together on the AUX port. When applying this connection, the amplifier will shut down and remain in sleep until the connection between pins 1 and 2 is open. While the amplifier is in sleep, the front panel power button is disabled. When the connection between pins 1 and 2 is open, the amplifier will revert to its last configuration and begin to output audio within 20 seconds. Communication via the network will take as long as the network interface card boots. If the front power button is pressed while the amp is in sleep mode, the blue power indicator will blink twice.

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 2 and 3, there will be either a +5VDC potential or a 2Hz square wave (heart beat). This option can be found in the AMP INFO button on the main amplifier Configuration panel within Audio Architect.

Dante

Dante Introduction

Dante is a licensed technology from Audinate ^® . It uses standard Internet Protocols over a 100Mb or Gigabit network and is capable of transporting professional-quality, low-latency audio. Dante runs on inexpensive off-the-shelf computer networking hardware and does not require dedicated network infrastructure; Ethernet switches transmit Dante digital media streams alongside ordinary data traffic. The physical Dante connections must be made using Category 5e or Category 6 cables when using a Gigabit network (Category 5 cables may be used for purely 100Mbps networks).

The two Dante (RJ-45) ports on the back of the DCi DA amplifiers can be used to connect to other Dante-enabled devices for transmission and receival of high-resolution digital audio over standard Ethernet cabling. The Dante protocol supports 24-bit resolution with a sample rate of either 48kHz or 96kHz. All DCi DA amplifiers support 8 Dante input channels and 8 Dante output channels.

Dante Specifications

• Supports 48kHz or 96KHz sample rates
• 24-bit audio resolution
- Dante data can co-exist on a network alongside control information and other standard data traffic
- Supports high channel counts; maximum channel count varies based on network speed (e.g., 100Mbps, Gigabit, etc.)
- Dante protocol based on networking technology standards, allowing the transport to operate with off-the-shelf networking peripherals
- 100m/328ft over Category 5e or Category 6 cable between devices (Category 5 cable can be used for purely 100Mbps networks)
• Supports fiber runs using fiber-enabled network switches

• Typical Dante transport latency contribution to a system is approximately 150μs or less
• Supports unicast (point-to-point) or multi-cast (one-to-many) audio packet transmission
• Supports redundancy using the Secondary Dante ports and a second network switch

Hardware Configuration

Dante devices have two Dante ports. One is the Primary and the other is the Secondary. When using only two Dante devices, the devices can be connected directly together. When connecting more than two devices, they should be connected to an Ethernet switch using a star networking topology. If using the Secondary Dante ports for redundancy, the Secondary ports should be connected to a second switch and operated as a separate network.

Fault Tolerance

The DCi DA amplifiers have a Primary and a Secondary Dante port; Dante audio traffic is duplicated to both of these ports. The Secondary port can be connected to a secondary network switch for redundant operation in the event a primary cable connection or the primary network is compromised.

Mastership

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

In certain cases, it is possible to utilize devices of more than one Ethernet transport type (AVB, CobraNet™, or BLU link) connected within the same Dante network. In other words, if you're careful, you can design a Harman system which actually includes more than two transports.

For example, it's possible for a Harman system to have CobraNet™ audio being converted to BLU link audio (the BSS 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, BLU-326 and BLU-DAN all 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.

Can it be "slaved" to the clock of another transport?

AVB No

BLU link Yes

CobraNet No

Dante Yes

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

• 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)
• BLU link + Dante + CobraNet (CobraNet provides the clock)

Any multi-transport combination NOT specifically listed in the previous section is not allowed in Soundweb London systems (without being forced to use analog interconnects between transports). For example, Dante + 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 the devices on the network, and change to the network will trigger the negotiation to be started. There are various rules for determining which device on the network becomes clock master :

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

Dante LED indicators

These are found on the Dante ports on the back panel of the device and indicate the following:

• Green LEDs
  The green LED will light solid to indicate a network link is established and flash to indicate link activity.
• Orange LEDs
  The orange LED indicates network connection speed (off = 10/100Mbps, on = 1 Gbps)

Dante Routing

The DriveCore Install DA amplifiers can use both analog and/or Dante inputs.

All Dante routing must be configured using Audinate's Dante Controller software, which can be downloaded from https://www.audinate.com/products/software/dante-controller.

Once Dante audio has been configured, input levels can be adjusted in the DriveCore Install DA amplifiers by clicking the Input Icon > Input Configuration. This panel allows you to make changes to the levels of the various sources. This feature allows you to adjust for different signal levels from the source (i.e. if analog inputs are quieter than Dante inputs) or can be used as an additional gain if needed.

The meters on this panel allow you to see both Peak and RMS levels. You are also able to set the maximum input level for the amplifier which will affect all channels. Network Signal Status lights below each Dante input channel provide confirmation of Dante signal presence.

NOTE: Gain Mode for the analog inputs can be used to maximize the Signal to Noise Ratio.

Dante sample rate (read only). To change sample rate, use Dante Controller, then reboot the amplifier.

- MAC Address

MAC Address of the Primary Dante port.

- Version

Firmware version of the Dante module.

The analog inputs in the DriveCore Install DA amplifiers provide additional flexibility when using the amplifiers Dante outputs. From the Dante Output Configuration window (Input Icon > Output Configuration), it is possible to utilize the DCi DA amplifier to be a Dante On-Ramp in two different ways:

- Send unprocessed audio from the analog inputs of the amplifier to one of the 8 available Dante outputs

NOTE: The audio from the analog inputs passes though the amplifier input gain stage (affected by selecting 28dB or 34dB of gain), and then through the input trim and polarity switches in the Source Routing - Input Configuration panel, before being sent to the Dante network.

- Send post-processed audio from a DCi DA amp output channel to one of the 8 available Dante outputs

NOTE: The post-processed audio is bussed from a point at the end of the entire channel processing chain in the DCi DA. This is effectively analogous to taking the audio from the physical output of the amplifier feeding a loudspeaker, and routing it onto the Dante network.

After selecting an Audio Source in the dialogue shown above, you must also route the Dante audio using the Dante Controller software.

NOTE: When connected to a Dante network running at 96kHz, the DCi DA's Dante outputs will be disabled and the amp will not be able to transmit audio onto the Dante network. The amplifier will be able to receive a full compliment of up to 8 Dante streams to send to the input router, but it will not be able to output any audio signals back onto the Dante network.

Advanced Operation

Introduction

Your DCi DA amplifier has a wide variety of onboard Digital Signal Processing (DSP). HiQnet Audio Architect software lets you adjust the DSP settings, such as filter slope, compression ratio, EQ frequency bands, and so on.

A preset is a group of DSP settings that configure the amp for a specific application. For example, you might use one preset that optimizes the amp's DSP for a JBL tri-amplified speaker setting. You might use another preset that sets up the DSP for a stereo pair of loudspeakers of your choice. You can choose any of 20 presets.

Amplifier Presets and Speaker Tunings

Preset 1 is the factory default preset and cannot be overwritten. It sets up the amplifier for pass-thru operation with no DSP features enabled. The DCi DA amplifier works with two types of presets:

User Presets – Using Audio Architect, you can create your own custom DSP presets, label them, and send them to the DCi DA amplifier. The amp stores those presets in firmware.

Downloadable Presets – Available for download from a variety of manufacturers, these presets are configured for optimal performance and can be sent to the amplifier via Audio Architect.

User Presets

User presets are DSP presets that are configured manually. The following three steps outlines setting up User Presets.

1. Adjust the DSP settings as desired in the Audio Architect software.
2. Save this group of settings as preset, you will be prompted to name it.
3. Download the preset to the DCi DA amplifier. See the software Help file for details. As soon as you save the setting as a preset, it is sent to the amplifier.

Speaker Tunings

Crown and JBL engineers have designed DriveCore Install DSP settings that are optimized for various JBL loudspeakers. Speaker tunings can be downloaded at the following website: www.jblpro.com. An improved speaker tuning approach has been developed for the DriveCore Install DA Series. The system is software library based rather than device preset based. The new approach offers significant benefits:

• Unlimited number of tunings organized into an unlimited number of libraries
• Simple and fast drop-down tuning recall/store/delete within device GUI
• Channel/band specific tunings – no more managing tunings across channels or amp chassis. Also yields logical one-to-one correlation of amp output to transducer/band.
• Faster tuning load/store times – much easier to compare and run A/B tests on multiple tunings without audio dropouts
• Library based – allows logical groupings and archiving of similar tunings (e.g. Screen Array Series or VTX Series, etc.)
• Tunings can be held within but are de-coupled from device presets. Eliminates concern of accidentally deleting or changing other device parameters – speaker tunings only contain the parameters required for speaker tunings! Now presets can be used for complete device configurations – as intended.
• Simpler and faster third-party and user tunings and libraries development – more people will be willing to develop custom or 3rd party tunings
• Single panel access to all required tuning parameters – easier/faster to create/modify tunings.

Speaker Tuning Panel

A new "speaker tuning" icon is implemented on the main device panel for each channel of DCi amplifiers. Double-clicking the speaker tuning icon will open the basic Speaker Tuning Panel (STP).

Speaker Tuning Libraries

The new system uses software based Speaker Tuning Libraries. Audio Architect manages these libraries within the device DLL. A library can contain any number of tunings. Audio Architect can manage any number of libraries. The library system implemented includes:

Working Library

The working library is opened and active when opening any Speaker Tuning Panel. The working library is automatically updated with the latest stored tunings/settings when exiting the open STP. Audio Architect is installed pre-configured for DCi amplifiers with a working library previously loaded with JBL Screen Array tunings from the JBL Master Screen Array Library.

NOTE: Multiple STP's can be opened but only the last parameters on the last panel closed are saved to the working library.

JBL Master Screen Array Library

This library is included with Audio Architect at install. The tunings in this library were developed and validated against previous same tunings for Crown DSI amplifiers. It is read-only to prevent over-write. At any time, a user can load this library to access reference JBL tunings for these devices.

User Libraries

At any time, the user may save the current working library to a custom user library file.

Loading a Library

Click on the File/Open > Speaker Tuning dialog on the device main panel to open and load an existing library file into the working library. This action replaces the current working library. Any changes not saved to the existing working library will be lost.

Saving a Library

Click on the File/Save > Speaker Tuning dialog on device main panel to save the current working library to any filename.

NOTE: JBL files are write-protected/read-only and cannot be over-written.

Library File Locations

The file location and naming conventions for all speaker tuning libraries is:

• Windows 7 and Windows 8.1 path C:\ProgramData\Harman Professional\Audio Architect\
• Windows XP path C:\Documents and Settings\All Users\Application Data\Harman Professional\Audio Architect\

Library Filename Conventions

The general file names are:

• Working Library: Crown Library.DCi Series.SpeakerTuning
- JBL Screen Array Library: JBL Master Screen Array Library.DCi Series.SpeakerTuning
- User Libraries: Any_user_file_name.DCi Series.SpeakerTuning

Input Signal Level Meter (green)

The measurement range is from 0dBFS to -40dBFS with 0.5dB resolution. Each audio channel has the following monitors:

• Switched Audio Input: This meter shows only the switched (selected) audio input after the Input Audio Router.
• Clip Indicator
• Peak + RMS levels

Output Signal Level Meter (blue)

The measurement range is from 0 dB to -40 dB with 0.5 dB resolution. The monitors are scaled so that 0 dB is referenced to the full rated output voltage of the amplifier. The wider left meter is rms and the right meter is peak for each channel. An output clip indicator is provided.

Indicators

• Temp: Lights if the temperature of the amplifier is too high and the amplifier is near shutdown.
  Green: Thermal headroom used up is less than 59%.
  Yellow: Thermal headroom used up is 60-80%.
  Red: Thermal headroom used up is more than 81%.

• Limit: Lights when the amplifier signal is being limited.

• Load: Lights when the load impedance is out of range.
• Ready: Lights when the amplifier is on and ready to supply power.
• Fault: Lights when the amplifier is in a fault mode service may be required.

Software-Controllable Onboard DSP

Crown DriveCore Install DA amplifiers have Digital Signal Processing built into the amplifier.

When you use a DriveCore Install DA amp, the loudspeaker processors, crossovers, limiters and delays are in the onboard DSP – so discrete rack mount devices are not needed. This drastically cuts setup time, commissioning, rack space and costs. The DriveCore Install DA DSP can be monitored and controlled with a computer running Audio Architect software, and connected to the amplifier Network Connector by a Category 5 Network cable.

Some applications for this DSP are:

• Configure signal flow
• Optimize system gain structure
• Configure speaker configurations (set the drive levels, frequency bands, delays and limiting for your particular speakers)
• Configure EQ, filtering, and much more

See the Audio Architect Help files for more detailed information.

Figure 39: Onboard DSP controllable from Configuration panel

On the left of this panel is the Input and Output Signal Level Monitor. On the right side are rows of DSP selection buttons for each channel. When you double click on a button, a control panel opens for that button's function.

Also on the right are buttons that open control panels for these functions:

• Amplifier mode
  • Signal generator (pink noise and sine wave)
• Amplifier information
• Recall and store presets
• Preset manager
• Apply to others (apply this amplifier's DSP settings to other devices)

These functions will be further explained on the next several pages.

Input Signal Router

Each channel of the DriveCore Install DA signal processing has an Input Signal Router that lets you choose the audio signal that will be used by the channel.

• Analog Audio: This selection configures the input router for analog sources. Each output channel will select its corresponding analog input. Choices for the Analog Audio input are any available analog input channels or one of the summed variants (e.g. Analog Input 1+2, Analog Input 3+4, etc.). Selecting Analog only will automatically change the MEDIUM input source to none.
• Network Only: This selects the audio input from the Dante port on the back panel of the amp. Each amplifier has 8 Dante input channels, as well as summed variants (e.g. Dante Inputs A+B, Dante Inputs C+D, etc.).
• Network With Analog Backup: The input takes the network signal as its source when the network signal or just the network clock is present. If the network lock is lost, the input switches to the selected Analog Source. Once that network lock is found again, the input switches back to the selected network source. This works even when the network signal has no audio but is sending a clock signal.
• Analog Overrides Network: Dante input is used as the channel's source. If the analog signal level is greater than an Analog Signal Threshold, which is user-defined, the input switches to the analog signal. As long as the analog signal level exceeds the threshold, or as long as its level falls below threshold for a user-defined hold time, the analog signal remains the channel's source.

The control operation will vary based on the mode that is selected.

LevelMax™ Suite

This is a suite consisting of a peak voltage limiter, RMS power limiter, clip limiter and transducer thermal limiter. First you will set the mode to automatic or advanced: See Figure 45.

• Automatic mode: The software determines the best settings based on the signal characteristics. You can modify only the RMS threshold, Speaker Thermal threshold and time constant. Everything else is set automatically.
• Advanced mode: You can modify the RMS threshold, Speaker Thermal threshold, time constant, Peak threshold and Peak/RMS release. Peak Voltage Limiter This limits the peak voltage output of the amplifier.
• On: Enables or disables this function. You'll set the parameters below:
  • Threshold: Sets the level, in absolute voltage, which the limiter will allow from the amplifier. The range is from 1 Vpk to 255 Vpk.
• Attack Time: Sets the attack time of the limiter. The attack time is defined as the time it takes the limiter to attenuate the output signal by 20 dB. The range is from .1 millisecond to 100 milliseconds. The Instant setting attack time is instant (0 millisecond).
• Release Time: Sets the release time of the compressor. The release time is defined as the time it takes the limiter to increase the output signal by 20 dB. The range is the same range as attack time above.

Protection System

Thermal Indicator

If the amplifier becomes too hot for safe operation, the channel that is generating too much heat will be shut down until the temperature drops below the thermal limit. The front-panel thermal indicator will illuminate at 80 degrees Celsius, indicating the onset of compression affecting the audio signal. 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 98 degrees Celsius.

Fault

The amplifier will enter a Fault state if the amplifier 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 2 - 16 Ohm limit (4 - 16 Ohm Bridge Mono). If wiring is verified as correct and the fault condition persists, see "Service" on page 52 for servicing information.

Auto Insertion High-Pass Filters

A 35 Hz high-pass filter is inserted automatically when a channel is selected for Hi-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 turns off and the blue Power LED flashes. The amplifier will turn back on when the AC line voltage returns to safe operating levels.

Breaker

The DCi 4|1250DA and 8|600DA models utilizes a resettable breaker. Please contact Crown Service department for more information.

Fan-Cooled Chassis

DCi Series amplifiers are cooled by quiet, variable speed fans. Maximum fan noise level of a DCi amplifier is 47 dBA. The fans will pull air from the front of the amplifier to the rear of the amplifier.

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

• High Frequency fault
• DC fault
• Short circuit fault
• Thermal fault
• Rail fault
  • After a fault, the fan will remain at full speed for at least 60sec

Universal Switching Power Supply

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

Troubleshooting

Fault Thermal Clip -10 -20 Signal Ready Bridge	Power Data	CONDITION: Power indicator is off. Mains indicator is off. POSSIBLE REASON: • The power supply breaker has tripped. • The amplifier has lost AC Power. • The amplifier is not plugged in to the power receptacle.
Fault Thermal Clip -10 -20 Signal Ready Bridge	Power Data	CONDITION: Power indicator is flashing. POSSIBLE REASON: • The AC line voltage has dropped below 10% or has risen above 10% of the nominal line voltage of the power supply. • When the Amp is in Sleep Mode as set by the AUX Port, the amplifier will not power up until the ground closure on the AUX Port is released. When the power button is pushed in this condition, the Power Indicator will flash for 2–3 seconds.
Fault Thermal Clip -10 -20 Signal Ready Bridge	Power Data	CONDITION: Thermal indicator is on. 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 mode-switch setting.
Fault Thermal Clip -10 -20 Signal Ready Bridge	Power Data	CONDITION: Fault indicator is flashing. POSSIBLE REASON: • There are a number of conditions that result in the Fault indicator flashing: temperature above 98C, DCy/LF protection is engaged, HF detect, output short circuit detected. These conditions should all be checked and attempted to be resolved before the amp is shipped back for service.

Key ● Off - - Flashing ○ Off/Flashing/On - - Lit

"Off/Flashing/On" above means that the LED can be off, or flashing, or on.

CONDITION: Distorted sound. POSSIBLE REASON: • Load is wired incorrectly or Stereo/Bridge mode switch is set incorrectly. Check both. • Input is overloaded by a signal level that is too high. Turn down your amplifier level controls, or turn down the input signal, until the clip light goes out. NOTE: If the signal sounds distorted even though the Clip LED is off, the input signal may be dis-torted before it reaches the amplifier input. Check gain staging and output levels of the mixer or preamp..
CONDITION: No sound, even though the amp has power. Power LED is on with out flashing and the amp is receiving an input signal. Signal indicator is flashing. POSSIBLE REASON: • Speakers not connected. • Open circuit due to speaker failure.
Fault Thermal Clip -10 -20 Signal Ready Bridge	• Based on the front panel LEDs, determine which channel has a short. Remove the associated input connector to ensure that no voltage will be present on the output. Remove the shorted load (and possibly attached cables) and have it checked by a qualified technician.

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

No person has the authority to enlarge, amend, or modify this Crown Warranty. This Crown Warranty is not extended by the length of time which you are deprived of the use of the new Crown product. Repairs and replacement parts provided under the terms of this Crown Warranty shall carry only the unexpired portion of this Crown Warranty.

DESIGN CHANGES

We reserve the right to change the design of any product from time to time without notice and with no obligation to make corresponding changes in products previously manufactured.

LEGAL REMEDIES OF PURCHASER

THIS CROWN WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS, YOU MAY ALSO HAVE OTHER RIGHTS WHICH VARY FROM STATE TO STATE. No action to enforce this Crown Warranty shall be commenced after expiration of the warranty period.

THIS STATEMENT OF WARRANTY SUPERSEDES ANY OTHERS CONTAINED IN THIS MANUAL FOR CROWN PRODUCTS. 04/15

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.
