Hardware Setup and Configuration

Wire 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 connectors for odd-numbered channels (1,3,5,7) for each bridged pair need be wired.

For BLU link audio connection, standard Category 5e cabling can be used. To increase fault tolerance of the BLU link audio ring, the input and the output should be connected to adjacent BLU link nodes. There is a maximum limit of 60 BLU link nodes for each audio ring.

Figure 3 BALANCED LINE INPUT SOURCE UNBALANCED LINE INPUT SHIELD SOURCE

Figure 4

Wire Output Connectors

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 (2|2400N and 4|2400N models require TE part #1958480-1 or equivalent). 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

Figure 5 CLASS 2 WIRING OUTPUT

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.

Hardware Setup and Configuration

Connect 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 Amplifiers utilize a universal power supply. The AC voltage requirements are 100VAC - 240VAC, 50/60Hz (+/-10%). If the voltage exceeds these requirements, then 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 down the input attenuators of the amplifier.
3. Turn on the "Power" switch. The Power indicator should light.
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. Turn up the level controls on the amplifier to the desired loudness or power level.

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 Page 8 of this manual. 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.

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

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

3. Do not operate the amplifier with the RED Clip LEDs constantly flashing.

4. 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.

5. 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

Connect Loudspeakers and Configure for Loudspeaker Load

Determine load impedances and power requirements

Before making any connections, carefully check and review the total impedance for loudspeaker systems to be connected to each amplifier output. If multiple loudspeakers are connected to one output (in series, parallel or series-parallel) for Low-Z operation, be certain the total system impedance is within allowed specification for the output. When multiple loudspeakers are connected to one output for Hi-Z operation, be certain total tapped power is below the rated power output for the channel.

Note: Illustrations and some text references are for channel pair 1 - 2 only. Connections and settings are identical for channels 3 - 4 on four-channel models and for channels 5 - 6 and 7 - 8 on eight-channel models. Each channel may be configured independently on multichannel models.

Set Up and Configuration of the DriveCore Install Network 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: the BLU link digital audio transport connectors cannot be used for control and monitoring of the amplifier.

To quickly configure your DriveCore Install Network 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 DEVICE tab on the left hand tree menu. If the devices are not found, then the network may not be configured correctly.

• Undo Current Edits - Resets any open edits in the grid to the values as currently on the network.
• Apply Current Edits - Confirms any open edits in the grid. Devices update accordingly until connection is reestablished with HiQnet NetSetter
• Apply and Exit - Confirms and saves any open edits in the grid. The devices update accordingly until connection is reestablished with HiQnet.

Exit HiQnet NetSetter - If you have made changes to NetSetter, and attempt to exit the program the following window will pop up.

Figure 8

Exit without applying current edits? OK Cancel

Clicking "OK" will apply the edits you have made since opening NetSetter. Clicking "Cancel" will return you to the program.

The NetSetter Grid

The grid is divided into 12 sections:

1. MAC Address 7. Random ID checkbox
2. DHCP / Auto-IP checkbox 8. Status
3. IP Address 9. Device Type
4. Subnet Mask 10. Device Name
5. Default Gateway 11. Container : Position
6. HiQnet ID 12. Locate

MAC Address

Displays the MAC Address(es) of the discovered device.

If more than one MAC Address is discovered for a single device (HiQnet device MAC Address / AVB card MAC Address etc), the field is represented as a drop list. You may select between the connected MAC Addresses. The data in this field cannot be edited.

- For a device connected to the same control network with two control MAC Addresses, the MAC Address field will be displayed in red.

DHCP / Auto-IP

If the discovered device is set to use DHCP / Auto-IP, the check box 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 set to DHCP / Auto-IP on by checking the check box in the column header. The individual check boxes for all devices will be checked. If a single individual check boxes for all devices is subsequently unchecked the column header DHCP / Auto-IP checkbox will be automatically unchecked.

The devices in the current filter view may be set to DHCP / Auto-IP off by unchecking the check box in the column header.

DHCP server status will be among the information displayed at the bottom of the window. If a DHCP server is not detected, the information will read 'DHCP server not detected'. Checking a device's DHCP / Auto-IP check box has no immediate effect on the column sort order. Once edits have been made, it is critical to click the "Apply Current Edits" or "Apply and Exit" buttons.

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.

Devices discovered with a conflicting IP Address

A discovered device with an IP Address that conflicts with one that has already been discovered 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.

Once edits have been made, it is critical to click the "Apply Current Edits" or "Apply and Exit" buttons.

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

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

Once edits have been made, it is critical to click the "Apply Current Edits" or "Apply and Exit" buttons.

Default Gateway

Displays the Default Gateway of discovered device

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

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

If the device is being rediscovered then:

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

Once edits have been made, it is critical to click the "Apply Current Edits" or "Apply and Exit" buttons.

HiQnet ID

Displays the HiQnet address of the discovered device.

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. No devices will be selected. If devices discovered with a conflicting HiQnet Address then:

• The HiQnet ID field of a discovered device with a HiQnet Address which conflicts with a HiQnet Address which has already been discovered will be displayed in pink.

• A conflicting HiQnet Address may be edited inline if you want to change the device 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.

Devices 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. The HiQnet ID field may not be edited inline.

Once edits have been made, it is critical to click the "Apply Current Edits" or "Apply and Exit" buttons.

Random ID

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 check box. If the check box 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 check box in the column header. The individual check boxes for all devices will be checked if a single individual check boxes for all devices is subsequently unchecked the column header Random ID checkbox will be automatically unchecked.

If all devices in the current filter view are set to Random ID on and the Random HiQnet ID column header check box is checked, all devices may be set to Random ID off by unchecking the column header check box. The individual check boxes for all devices will be unchecked.

Devices 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 check box will be unavailable.

Status

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

• 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.
• 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.
• 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.
• 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.
• Discovering. This condition will be displayed if the device has had changes made to IP configuration or HiQnet address and HiQnet NetSetter is waiting to reestablish connection. When a device being rediscovered is not selected, all fields within the device row are displayed but is grayed out, represented in light gray.

Discovered - 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
  IP conflict - 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 which conflicts with another device which has already been discovered by NetSetter

HiQnet conflict - 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 which conflicts with another device which has already been discovered by NetSetter

Locked - 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 Access Controlled

When the device has been discovered in the Locked state, a dialog must be displayed to prompt for the Admin password the first time any field is attempted to be edited

• A successful login with the Admin password only will enable all fields to be edited subsequently
• This state may need to be reset on rediscovery after applying current edits, requiring the Admin password to be entered again

Discovering - The 'Discovering' status is determined by the following conditions:

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

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. Unless 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.

Device Type

The device class name is displayed, as reported by the discovered device. To the left of each device class name is displayed the brand icon. The software application name is displayed for discovered PCs running an instance of HiQnet software:

Set-up and System Configuration

Low-Z (8Ω, 4Ω or 2Ω) Output Operation

Typical input and output wiring, along with Audio Architect software settings are shown in Figure 19.

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. If using the BLU link input, it is important to understand that BLU link is a digital audio bus and cannot be routed through a network switch or router. To increase fault protection, use both the input and output BLU link wiring connection. For BLU link routing, refer to page 33.

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 to Page 9 for output connector terminal assignments.

General Purpose In/Out Control Port

DriveCore Install Network amplifiers come with a 2-in, 2-out General Purpose In/Out (GPIO) control port in the form of either a 6 position RJ-11 connector (2|300N, 2|600N, 2|1250N, 4|300N, 4|600N, 4|1250N, 8|300N, 8|600N) or a block connector (2|2400N, 4|2400N). 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.

Configuration of 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-N 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.

General Purpose In/Out Control Port

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.

General Purpose In/Out Control Port

Configuration of 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

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 page within Audio Architect..

BLU link

BLU link

BLU link is an audio bus found on the DriveCore Install Network amplifier series. It carries 256 channels of audio at 48kHz, and 128 channels at 96kHz, both at 24bit. When connected in a loop, it has redundancy, allowing any one BLU link cable to break while still maintaining audio.

BLU link Specification

• Based on Gigabit Ethernet technology
  • 100m over CAT5e cable between each point.

• 100m using fibre converters.
  • 256 Channels at 48KHz
  • 128 Channels at 96KHz

• Bus-like architecture. Audio transmitted on a channel is available at all other devices on the network automatically.
• Wired in a loop for redundancy
  • Recovers from a single cable break

Hardware Configuration

On the rear of the BLU link devices there are two BLU link ports. One is the BLU link In, and the other BLU link Out. Devices are connected together by wiring Out to In on all of the devices within your BLU link network, making sure that the loop is complete so that there are no empty BLU link ports. You should not connect the BLU link ports to anything other than BLU link ports. BLU link will not function if you try to connect the BLU link to an Ethernet switch for example.

Fault Tolerance

The network is capable of a degree of fault tolerance due to the fact that each device receives the same audio from 2 other devices. If a cable is broken the devices which are no longer connected will detect the cable break. One device will detect that its 'In' port is unconnected and the other will detect that its 'Out' port is undetected.

NOTE: when the cable is broken, the audio takes longer to reach its destination than before. This added delay is not compensated for in any way, but is a side-effect of the way the fault tolerance works.

Host

The BLU link network requires one device on the ring to act as host for the whole ring. The host will provide the clock for all the other devices on the ring. This means that the whole ring 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 Dante) connected within the same BLU link ring. 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 (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 "client" (AKA "re-clock") to a clock being generated by a separate transport.

Can it be "connected" 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

Any multi-transport combination NOT specifically listed above 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 the devices on the ring, and change to the ring will trigger the negotiation to be started. There are various rules for determining which device on the ring becomes clock host :

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

BLU link LED indicators

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

- Green LEDs

The green LED will indicate a link on that particular port

- Orange LEDs

Both on: The box is the host. (No green LEDs will be on if no cables are connected).

Only one on: The box is locked to the data coming in on that particular port

Both off: Boxes not locked

BLU link Routing

The DriveCore Install Network Amplifiers series can utilize both analog and/or BLU link inputs

The DriveCore Install Network Amplifiers series can utilize both analog or BLU link inputs. To configured the input section of the amplifier, Input Icon > Source Routing > Input Configuration. This page allows you to make changes to the levels of the various sources. This feature allows you to not only adjust for different signal levels from the source (i.e. analog is quieter than BLU link) as well as being able to be used for an additional location of gain if needed. The meters on this page 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 both channels. Rx Status lights below each BLU link input channel provide confirmation of slot assignment.

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

BLU link Routing

Double-clicking on the BLU link Routing button opens the BLU link channel assignment dialogue. The DCi-N amplifiers have 8 'slots' (labeled A through H) available for receiving a BLU link audio stream, which can then be sent to any one of the channels in the amplifier via the Source Routing panel. Click and drag a stream from the list of BLU link channels on the left, and drop it into one of the 8 channel slots (A-H) available on the right side of the dialogue labeled Output Channels. Then go to Source Routing to assign that audio stream to an amplifier channel by selecting BLU link Input A through H from the dropdown menus presented. If you know the BLU link channel number you want to use, it can be assigned to a slot (A-H) on the Input Source Routing window by typing the BLU link channel number into the field next to the desired input slot letter. Press enter after entering the number for changes to take effect

Figure 33 BLU link Output Configuration

The analog inputs for the DriveCore Install Network amplifier provide additional flexibility when for the BLU link digital audio bus. From the BLU link Output Configuration window (Input Icon >Source Routing >BLU link Output Configuration), it is possible to utilize the DCi-N amplifier to be a BLU link On-Ramp in two different ways:

Send unprocessed audio from the analog inputs of the amplifier to 1 of the 8 available BLU link 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 BLU link bus.

Send post-processing audio from a DCi-N amp channel to 1 of the 8 available BLU link outputs

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

After selecting an Audio Source in the dialogue shown above, double-click on the BLU link Routing button. It is absolutely necessary to take this additional step, which allows the 8 BLU link output slots inside DCi-N to then be routed onto one of the slots available on the larger BLU link audio ring.

NOTE - BLU link OUTPUTS (ON-RAMP FROM DCi-N TO BLU link ) ARE DISABLED WHEN THE BLU link NETWORK IS OPERATING AT 96KHZ SAMPLING RATE

When attached to a BLU link network running at 96kHz, DCi-N will not be usable as an on-ramp. The amplifier will be able to receive a full compliment of up to 8 streams to send to the input router, but it will not be able to send any analog or post-processing audio signals back onto the BLU link network.

Advanced Operation

Introduction

Your DriveCore Install 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 DriveCore Install 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 DriveCore Install 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 DriveCore Install amplifier. See the software Help file for details. As soon as you save the setting as a preset, it is sent to the amplifier.

Advanced Operation

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 Network 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 host 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.

Advanced Operation

JBL host 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 host Screen Array Library.DCi Series.SpeakerTuning

When you use a DriveCore Install Network 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 Network 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.

This panel is on the left side of the DriveCore Install Network main control panel shown above. Channels 1, and 2 Level Controls set the input signal level of each channel. Each channel can be muted, and both faders can be linked with the Link button.

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.

Advanced Operation

Input Signal Router

Each channel of the DriveCore Install 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 set up the input router for analog sources. Each output channel will select its corresponding analog input. Choices for the Analog Audio input are Channel 1, Channel 2, or a sum of Channels 1 and 2. Selecting Analog only will automatically change the MEDIUM input source to none.
• BLU link Digital Audio: This is the audio input from the BLU link connector on the back panel of the amp. Each amplifier has 8 BLU link input channels, plus 4 pairs of BLU link summed channels. This does not represent the BLU link channels 1-256, but rather the BLU link input channels that have been assigned to amplifier input slots A-H..
• Digital with Analog Backup: The input takes the digital signal as its source when the digital signal or just the digital clock is present. If the digital lock is lost, the input switches to the selected Analog Source. Once that digital lock is found again, the input switches back to the selected digital source. This works even when the digital signal has no audio but is sending a clock signal.
• Analog Overrides: BLU link input takes the digital signal as its source. If the analog signal level is greater than an Analog Signal Threshold that the user defines, 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 input remains the analog signal

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 43.

• 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.

Per Channel Settings

Channel Attenuators

Each channel is supplied with a logarithmic 21-position detented input attenuator. Use a flat-blade screwdriver to set input level. Attenuation is from -95 dB (full counter-clockwise) to 0 dB (full clockwise). For gain structure purposes, it is important to note that attenuators are at the end of the DSP signal chain.

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 Page 63 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.

Fuse

A fuse (F1) located near the IEC power inlet protects the amplifier from excessive AC current draw. The DCi2|2400N, 4|1250N, 4|2400N, and 8|600N models utilizes a resettable breaker instead of a fuse.. 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.

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 http://www.crownaudio.com/en/support/service_lookup

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.

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.
