Hardware Setup

Connecting the AC Power Cord

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

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

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

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

Power Up Procedure

When turning on the ampliﬁer for the ﬁrst time:

1� Ensure all connections are disconnected with the exception of the power cord. 2� Press the ampliﬁer's POWER button. The Power indicator will light blue and the ampliﬁer will boot as long as sufﬁcient mains power is provided. 3� Once boot up is complete, turn the ENCODER counter-clockwise until all amp levels are set to -80dB in the front panel LCD. 4� Conﬁgure the ampliﬁer as described in "Conguring the Amp" on page 11.

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

5� Once the ampliﬁer has been properly conﬁgured for the application, turn off the power — by pressing and holding the Power button for 2 seconds —

then disconnect the power cord.

6� Turn down the level of your audio source. 7� Make all connections as described in "Wiring Input Connectors" and "Wiring Output Connectors" on page 7. 8� Once all connections have been made, reconnect the power cord and turn on the ampliﬁer power. 9� Turn your audio source up to an optimum level. Refer to all device meters and ensure that at no point in the signal chain is the signal being clipped in

any way. If any of the ampliﬁer's Clip indicators light yellow, reduce the source level until the Clip LEDs no longer light.

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

light.

"Conguring the Amp" on page 11 for more information.

IMPORTANT: Always turn off the ampliﬁer — by pressing and holding the Power button for 2 seconds — and disconnect the power cord before making

any wiring or installation changes.

IMPORTANT: When powering a fully conﬁgured PA system, always turn the ampliﬁers on last and off ﬁrst. For help with determining your system’s optimum gain structure (signal levels) please refer to the Crown Ampliﬁer Application Guide, available online at

www.crownaudio.com.

Precautions

Your ampliﬁer is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety: 1� Conﬁgure the ampliﬁer for proper operation, including input and output wiring hookup. Improper wiring can result in serious operating difﬁculties.

For information on wiring and conﬁguration, please consult "Wiring Input Connectors" and "Wiring Output Connectors" on page 7. For advanced setup techniques, consult Crown’s Ampliﬁer Application Guide available online at www.crownaudio.com.

2� Use care when making connections, selecting signal sources, and controlling the output level. The load you save may be your own! 3� Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and cause oscillations.

4�

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.

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

Wiring Input Connectors

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

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

Figure 4 shows connector pin assignments for balanced wiring and Figure 5 shows connector pin assignments for unbalanced wiring. Note that for

bridge mono operation, only the odd-numbered input channels (1,3) should be wired for each bridged pair.

Figure 4: Balanced wiring Figure 5: Unbalanced wiring

Wiring Output Connectors

IMPORTANT: The ampliﬁer output mode (Low Z, 70V, 100V) must be properly conﬁgured for the application before connecting the speakers. By default, all outputs are conﬁgured for Low Z operation. See "Conguring the Amp" on page 11 for more information.

Before making any output connections, ensure the power cord is disconnected from the ampliﬁer and carefully review the total impedance for loudspeakers connected to each ampliﬁer output. If multiple loudspeakers are connected to an output in Low Z mode (i.e., in series, parallel, or series-parallel), be certain the total system impedance is within allowed speciﬁcation for the output. When multiple loudspeakers are connected to one output in High Z mode, be certain total tapped power is below the rated power output for the channel. See "Specications" on page 78 for supported load speciﬁcations.

NOTE: The Crown-designed output cover does not need to be removed to connect the output wiring. Crown recommends using the included terminal fork connectors and two-conductor or four-

conductor, heavy gauge speaker wire. You may use terminal forks up to 10 AWG or bare wire for your output connectors (see Figure 6). For best results, Crown recommends Panduit part #PV10-6LF-L or equivalent terminal fork. For bare wire, it is highly recommended that output wiring is tinned. To reduce strain on input and output wiring, Crown recommends the use of horizontal lacer bars. For best results, Crown recommends Middle Atlantic® part# LBP-4R90 or equivalent horizontal lacer bar.

For low-impedance loads, refer to the table below and select the appropriate size of wire based on the distance from ampliﬁer to speaker.

Distance Wire Size

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

CAUTION: Never use shielded cable for output wiring.

Figure 6: Wiring output connectors

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.

• Thermal Voltage (1 – 500V) Sets the long-term output power limit of the ampliﬁer to what the loudspeaker load can handle without overheating and going into thermal compression. This is based on the AES power/voltage ratings of drivers outlined in the AES2-2012 standard.

• Thermal Response (1 – 600 sec) Sets the time it takes for the thermal limiter to adjust output voltage. This is based on the AES power/voltage ratings of drivers outlined in the AES22012 standard.

NOTE: The LevelMax limiters include sidechain EQ for advanced speaker tunings. Sidechain EQ parameters are not user adjustable. Additional limiter parameters are available in Audio Architect. For more information, see "LevelMAX Panel" on page 45. For more information on the LevelMAX limiters and how to set the parameters, see the LevelMAX white paper available at www.crownaudio.com.

Conﬁguring BLU link Settings

The BLU link Settings menu is only available in BLU link CDi DriveCore models. From the BLU link Settings menu (see Figure 23), BLU link sample rate, clock priority, and outputs can be conﬁgured.

To congure BLU link settings:

1� From the Home screen, press the MENU button. 2� Select the "BLU link" option from the menu using the ENCODER. 3� Select the "BLU link Settings" option from the menu. 4� Select the desired options for your application, making selections with the ENCODER. 5� When done, select "Done" at the bottom of the screen.

Figure 23: BLU link Settings menu

Available options:

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

NOTE: The sample rate must be set to match all other devices on the BLU link bus in order to pass BLU link audio. NOTE: The CDi DriveCore ampliﬁers process audio using a ﬁxed 96kHz internal sampling rate. When using a BLU link sample rate of 48kHz, the

audio signal from the BLU link bus will be sample rate converted from 48kHz up to 96kHz when entering the amp, and any audio signals sent from the amp back to the BLU link bus will be converted from 96kHz down to 48kHz.

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

• Priority (0-254) Determines which device on the BLU link bus will provide audio clock for the entire bus. The higher the value, the higher the priority. Under certain conditions, such as when two devices have the same Priority settings, other factors may be used to determine BLU link clock priority (see"Mastership" on page 61 for more information).

• BLU link Channel Output 1-4* (Off, 1-254 @ 48kHz / 1-128 @ 96kHz) The CDi DriveCore ampliﬁers are capable of outputting up to 2 channels (2-channel models) or 4 channels (4-channel models) of audio onto the BLU link bus. These options allow you to assign the desired BLU link output channels. Channels 1-256 are available when using a 48kHz BLU link sample rate and channels 1-128 are available when using a 96kHz BLU link sample rate.

• BLU link Source Output 1-4* These options allow you to select the source to route to each BLU link output channel, with the following options available:

• Analog Input 1-4* (routes the pre-processed audio signal from the input)

• Amp Output 1-4* (routes the same audio signal present at the ampliﬁer outputs)

For information on routing BLU link channels to the ampliﬁer's inputs, see "Assigning Input Sources" on page 14. For information on conﬁguring BLU link output settings in Audio Architect, see "Conguring BLU link Outputs" on page 38. *Channel 3 and 4 options available in 4-channel CDi DriveCore models only.

Introduction to HiQnet Audio Architect

CDi DriveCore ampliﬁers can be set up from either the front panel or from the HiQnet Audio Architect software program. Access to some settings and functionality are only available from Audio Architect.

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

NOTE: The BLU link ports available on BLU link CDi DriveCore models cannot be used for network control and monitoring of the ampliﬁer. When Audio Architect is ﬁrst loaded, the software will scan the network for HiQnet devices. All devices that are discovered on the network will be found

under the Device Tree menu in the left-hand side of the Main Audio Architect window (see

Figure 24).

Figure 24: Device Tree menu

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

The NetSetter Grid

The NetSetter grid is divided into the 12 sections described below.

Figure 28: NetSetter grid

1� MAC Address

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

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

2� DHCP/Auto-IP

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

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

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

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

3� IP Address

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

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

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

4� Subnet Mask

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

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

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

CDi DriveCore Series Operation Manual

Page 27

Page 30

Installing Audio Architect & Conguring the Network

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.

Page 28

CDi DriveCore Series Operation Manual

Page 31

Installing Audio Architect & Conguring the Network

• The device is not access controlled.

b� IP Conﬂict

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

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

• The device is discoverable at the MAC address level.

• The device has an IP address that conﬂicts with another device which has already been discovered by NetSetter.

c� HiQnet Conﬂict

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

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

• The device is discoverable at the MAC address level.

• The device has a valid and unique IP address (manual or DHCP/Auto-IP).

• The device has a HiQnet address that conﬂicts with another device which has already been discovered by NetSetter.

d� Locked

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

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

• The device is discoverable at the MAC address level.

• The device has a valid and unique IP address (manual or DHCP/Auto-IP).

• The device has a unique HiQnet address.

• The device is access controlled.

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

e� Discovering

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

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

• The device had been previously discovered at the MAC address level.

• Edits had been made to one or more ﬁelds.

• The device is being rediscovered after applying current edits.

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

9� Device Type

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

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

NOTE: Devices are not discoverable at the IP or HiQnet level. A device which is not discoverable at the IP level (invalid IP address, etc.) or HiQnet

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

10� Device Name

The user-deﬁnable Device Name is displayed here, as reported by the discovered device. NOTE: This ﬁeld may be edited inline if you want to change the Device Name. This ﬁeld may not be edited for discovered PCs running an instance

of HiQnet software.

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

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

11� Container : Position

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

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

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

NOTE: Devices are not discoverable at the IP or HiQnet level. A device which is not discoverable at the IP level (invalid IP address, etc.) or HiQnet

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

12� Locate

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

one device can be located at any one time.

Using HiQnet Audio Architect

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

• Conﬁgure signal ﬂow

• Optimize system gain structure

• Conﬁgure DSP settings (set driver levels, crossover bands, delays, equalization, and limiting for your particular speakers)

• Conﬁgure output bridging, high Z/low Z operation, and much more

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

Launching the Audio Architect Software

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

Figure 29: Discovered Devices prompt

Using HiQnet Audio Architect

Ofﬂine & Online Operation Explained

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

When operating in Ofﬂine mode, the Ofﬂine Design ribbon is presented at the top of the Main Audio Architect window. From this window, discovered devices can be added to the venue by clicking on them in the Devices tab on the left and dragging them into the Room window on the right (see Figure 30). Note that when a device is added to the venue, it is automatically removed from the "Discovered" device list. If the "Add discovered devices to the Venue automatically" checkbox was checked upon launching Audio Architect, as previously mentioned, discovered devices were already added to the Venue and this step is not necessary.

Drag and drop to add device to venue

Figure 30: Main Audio Architect window

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

TIP: Double clicking a device image will open the device's Main Control panel (see

"Main CDi DriveCore Control Panel" on page 34 for more information).

Going Online

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

To go online:

1� From the Ofﬂine Design ribbon at the top of the Main Audio Architect window, click the Go Online

button. The Ofﬂine Design and Add Devices ribbons will now be replaced with the Online Operate ribbon and, in some cases, the Match Devices ribbon.

2� When going online, the following scenarios are possible:

a� If one or more devices in the venue are not matched AND corresponding devices are available

on the network, going online lands in Match Devices mode.

NOTE: Before you can go online with a device, it must be "matched". See "Matching

Devices" on page 33

b� If all the devices in the venue are matched, going online lands in Synchronize Venue mode. In

Synchronize Venue mode, Receive and Send icons will appear for each device in the venue, as well as for a rack if more than one device has been added (see Figure 32). This provides the ability to send/receive data either to/from a single device, or to/from all devices within the rack with a single click.

c� If no devices require matching or synchronization, going online lands in Run Venue mode. In this mode, Audio Architect is online with the

devices in the venue and real-time setting changes can be made.

for more information.

Figure 32: Send and Receive icons

Matching Devices

The Match Devices ribbon appears at the top of the Main Audio Architect window after clicking on the Go Online button from the Ofﬂine Design ribbon, then clicking the Match Devices button from the Online Operate ribbon.

Conﬁguring Inputs & Outputs in Audio Architect

Assigning Input Sources in Audio Architect

All channels of the CDi DriveCore signal processing share a single Input Selector panel (shown in

Figure 38). From this panel, you can select the audio signal that will be routed to each ampliﬁer

channel and adjust the levels entering each channel's DSP chain. The Input Selector panel can be accessed by clicking any of the INPUT buttons from the Main CDi DriveCore Control panel (see Figure 37).

1� Levels, Meters, & Clip Indicators

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

2� Input Selector Dropdown Menus

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

Figure 38: Input Selector panel (BLU link CDi DriveCore model shown)

Conﬁguring Inputs

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

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

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

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

Clicking the Advanced Settings button opens the Advanced Settings panel, where BLU link sample rate and mastership clock priority can be set. See "Conguring BLU link

Clock" on page 38

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

Conﬁguring BLU link Clock

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

page 62

Conﬁguring BLU link Outputs

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

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

NOTE: The audio from the analog inputs will still pass through the ampliﬁer input gain stage. This means the signals will be affected by the Gain Mode setting and the Input Level faders located in the Input Conﬁguration panel (

Figure 40) before being sent out to the BLU link bus.

Figure 42: Advanced Settings panel

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

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

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

NOTE: Audio Architect also provides the traditional BLU link Output Channel Assignment window ( link bus. Either method can be used to assign BLU link output channels.

Conﬁguring Amp Wiring & Output Modes in Audio Architect

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

• Inputs can be cascaded ("Y'ed") to multiple outputs.

• Output pairs can be bridged for mono operation.

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

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

Figure 45: Mode button

Cascading Inputs

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

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

Figure 46: Use the "Y" checkboxes to cascade input channels

Conﬁguring Outputs for Bridge Mono Operation

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

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

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

Figure 49.

Conﬁguring Outputs for Low Z/High Z Operation

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

Figure 50).

NOTE: If an ampliﬁer output channel pair is conﬁgured for bridge mono operation and

one of the High Z options is selected, the ampliﬁer output will produce 140V or 200V (rather than 70V or 100V).

• LevelMAX (Off, On) Turns the limiters on or off.

• Mode (Auto, Advanced) Sets whether certain parameters will be set automatically or available for manual conﬁguration. The following Mode options are available:

Auto Mode – When this option is selected, the software determines the best settings based on the signal characteristics. You can modify only the RMS Threshold, Thermal Threshold, and Thermal Time Constant. All other parameters will be set automatically.

Figure 58: LevelMAX button

Advanced Mode – Selecting this option allows the

parameters which are set automatically when "Auto" mode is selected to be manually adjusted. This includes Peak Threshold, Peak Release, and RMS Release.

• Peak Threshold (1 – 200 VPK) Sets the peak level, in absolute voltage, which the limiter will allow from the ampliﬁer. In Automatic mode, the Peak Threshold value is automatically determined from the deﬁned RMS threshold and the low pass frequency deﬁned in the crossover.

• Peak Release (0 – 10 seconds) Sets the release time of the peak limiter. The release time is deﬁned as the time it takes the limiter to increase the output signal by 20dB.

• RMS Threshold (1 – 400 VRMS) Sets the RMS level, in absolute voltage, which the limiter will allow from the ampliﬁer. The RMS Threshold should be set to correspond to the short term (2 hour) power handling of the transducer or system.

• RMS Release (0 – 10 seconds) Sets the release time of the RMS limiter. The release time is deﬁned as the time it takes the limiter to increase the output signal by 20dB.

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

Using BLU link

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

BLU link Speciﬁcations

• Based on Gigabit Ethernet technology

• Up to 100m over CAT5e cable between each point (>100m using ﬁbre converters)

• 256 channels at 48kHz

• 128 channels at 96kHz

• 24-bit audio resolution

• Bus-like architecture — audio transmitted on a channel is available at all other devices on the bus automatically

• Wired in a loop for redundancy — recovers from a single cable break

• Up to 60 BLU link nodes (devices) can exist in a single BLU link system

BLU link Latency

Path Total Latency (for selected path)

Analog Input to Ampliﬁer Output 1.78ms BLU link Input to BLU link Output (48kHz) 4.47ms BLU link Input to BLU link Output (96kHz) 3.57ms

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

Making BLU link Connections

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

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

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

BLU link Port LED Indicators

Each BLU link port has LEDs that indicate the following:

Both Yellow LEDs On

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

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

One Yellow LED On

This indicates the device is slaved to the BLU link clock received from the connected device. The green LEDs light to indicate the port has established a link with the BLU link bus.

No Yellow LEDs On

This indicates the device is not receiving BLU link clock and will not pass audio. This either indicates the IN and OUT ports are swapped (an OUT port is connected to an OUT port and an IN port is connected to an IN port), or there is a mismatch between the BLU link sample rates of the ampliﬁer and the connected device(s). See "Conguring BLU link Settings" on page 22 for information on conﬁguring the ampliﬁer's BLU link sample rate.

Using BLU link

Mastership

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

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

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

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

Transport Supports Slaving to Another Transport

AVB No BLU link Yes CobraNet No Dante Yes

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

Combined Transports Clock Master

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

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

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

• If there is only one BLU link device connected to CobraNet/AVB then that device is master.

• If there are multiple BLU link devices connected to CobraNet/AVB, then they compare master priorities.

• If there are multiple BLU link devices on CobraNet/AVB with the same highest priority, then they use MAC address to decide which is master.

• If there are no BLU link devices connected to CobraNet/AVB, then they ﬁrst compare master priorities. Next, if the priorities are the same, they compare MAC addresses.

Fault Tolerance

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

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

Device Presets

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

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

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

Using the GPIO Control Port

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

GPIO Pinout, Speciﬁcation, Use, & Conﬁguration

GPIO/AUX

AMP STATUS

SLEEP

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

Information" on page 35

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

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

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

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

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

Using the AUX Port

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

Sleep

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

Amp Status

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

Power Saving Modes

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

Auto Channel Disable (ACD)

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

NOTE: The ACD feature can be disabled or adjusted from the front panel (see "Power Modes" on page 67) or from Audio Artchitect (see

"Amplier Information" on page 35). Note that ACD will be re-enabled if the ampliﬁer is factory reset or the default preset is loaded.

Auto Power Down (APD)

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

• There is no signal level detected above approximately -50 dBu at any of the analog inputs

• There is no activity detected on the BLU link network (BLU link CDi DriveCore models only)

• The signal generator is not active

• There is no activity detected on the data network

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

• The POWER button is pressed (the sleep pin on the Aux port must also be open (not active))

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

The amplﬁer will take approximately 30 seconds to fully recover from APD mode. NOTE: The APD timer setting is defaulted to 30 minutes from the factory. This timer setting is user adjustable, but it is not available from any

preconﬁgured panels in Audio Architect or from the ampliﬁer's front panel user interface. To access the APD timer setting, the "AmAPDTimeoutSec" SV (located under [0x1]>AM3 in the Venue Explorer tree menu) must be added to a custom panel. Once the desired SV has been added to the custom panel, go online with the ampliﬁer, run the custom panel, then adjust the setting. See the Audio Architect help ﬁle for information on using custom panels in Audio Architect. APD can be disabled from the front panel (see "Power Modes" on page 67) or from Audio Artchitect (see "Amplier Information"

on page 35

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

contact Crown Technical Support.

). Note that APD will be re-enabled if the ampliﬁer is factory reset or the default preset is loaded.

System Protection

Faults

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

The following faults are possible:

HF Detect Channel Excessive high frequency signal content has been sensed at the output of the ampliﬁer. DCLF Channel Excessive DC or low frequency signal content has been sensed at the output of the ampliﬁer. Short Circuit Detect Channel A short is detected at the output of the ampliﬁer.

Thermal Channel/Power Supply

High Voltage Rail Power Supply

Low Voltage Rail Power Supply

AC Mains Power Supply The AC mains have reached an unsafe level.

"Service" on page 88 for servicing information.

Fault Fault Type Description

An amp channel and/or the power supply has exceeded the maximum acceptable temperature threshold.

The power supply's high voltage rails are no longer within a safe operating range for the ampliﬁer or other components attached.

The power supply's low voltage rails are no longer within a safe operating range for the ampliﬁer or other components attached.

Thermal Limit

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

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

Auto-Insertion High-Pass Filters

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

AC Under/Over-Voltage Protection

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

Fan-Cooled Chassis

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

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

• High frequency fault (excessive high frequency signal content has been sensed at the output of the ampliﬁer)

• Thermal fault (excessive power supply or channel temperature is detected)

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

System Protection

Universal Switching Power Supply

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

Troubleshooting

CONDITION: Power indicator and LCD are off.

POSSIBLE REASON

• The ampliﬁer is not plugged in to the power receptacle.

• The ampliﬁer has lost AC Power.

• The power supply fuse has tripped.

CONDITION: Power indicator is ashing blue indenitely.

POSSIBLE REASON:

• The AC line voltage has dropped below 10% or has risen above 10% of the nomi nal line voltage of the power supply. See "System Protection" on page 72 for information on AC under/over voltage protection.

Thermal fault displayed here

CONDITION: When pressing the Power button, power won't turn on and Power indicator ashes blue briey.

POSSIBLE REASON:

• The ampliﬁer is asleep via the Aux port (contact closure) circuit. See "Using the

AUX Port" on page 70

CONDITION: Thermal fault is indicated in the display.

POSSIBLE REASON:

• The ampliﬁer is becoming too hot for safe operation. Allow ampliﬁer to cool. Check for loads less than 2Ω and for excessive input levels. Check for proper ventilation and proper output mode (2/4/8Ω, 70V, 100V) set ting. See "Proper Cooling"

Fault displayed here

Troubleshooting

CONDITION: Some other fault is indicated in the display.

POSSIBLE REASON:

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

CONDITION: Distorted sound.

POSSIBLE REASON:

• Load is wired incorrectly or Dual/Bridge mode is conﬁgured incorrectly — both should be veriﬁed. See "Wiring Output Connectors" on page 7 and

"Conguring Outputs for Bridge Mono Operation" on page 40.

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

NOTE: If the signal sounds distorted even though the Clip LED is off, the signal may be 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 Power LED is lit blue and the level meters indicate the amp is receiving an input sig nal.

POSSIBLE REASON:

• Speaker not connected. Power off the ampliﬁer, disconnect the AC power cord, then verify speaker connection.

• Open circuit due to speaker failure. From the front panel display, determine which channel has the short. Power down the ampliﬁer then disconnect the AC power cable. Remove the shorted load from the channel (and possibly attached cables) and have it checked by a qualiﬁed technician. Reconnect the power cord and power up the ampliﬁer. If the shorted condition remains after the load is removed, the unit should serviced. See "Service" on page 88.

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

CDi DriveCore Series Operation Manual

POSSIBLE REASON:

• Input signal level is very low. Double check the gain structure of the system and ensure that the ampliﬁer's input trim levels are set accordingly.

• Input routing is not conﬁgured correctly for application. See "Assigning Input

Sources" on page 14

Factory Reset

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

• Erase all user presets (this includes all user DSP and conﬁguration settings)

• Reset all system settings

• Reset all BLU link settings (applicable to BLU link CDi DriveCore models only)

To perform the Factory Reset procedure:

Warning! All user presets will be permanently deleted and all settings reverted back to their factory default state. This process is irreversible. If you have

any user presets you wish to keep, they should be backed up using Audio Architect before performing the Factory Reset. See "Managing Device &

Preset Files" on page 47

1� Power off the ampliﬁer by pressing and holding the Power button for 2 seconds. 2� Press and hold the CH1 and CH2 SELECT buttons while powering on the amp. Continue to hold these buttons until the LCD reads: "Press MENU to

restore Factory Settings or any other button to exit". Now release the SELECT buttons.

3� Press and release the MENU button to start the Factory Reset procedure (pressing any other button will abort the Factory Reset procedure and the

amp will boot up normally).

4� Once the Factory Reset procedure begins, the LCD will display the message: "Restoring factory defaults!" and when complete, the device will boot up

normally.

Warranty (United States Only)

SUMMARY OF WARRANTY

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

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

ITEMS EXCLUDED FROM THIS CROWN WARRANTY

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

WHAT THE WARRANTOR WILL DO

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

HOW TO OBTAIN WARRANTY SERVICE

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

DISCLAIMER OF CONSEQUENTIAL AND INCIDENTAL DAMAGES

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

WARRANTY ALTERATIONS

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. A list of authorized service centers in your area can be obtained from Crown Factory Service, or online from www.crownaudio.com/en/support/service_lookup

Factory Service

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

A Service Return Authorization (SRA) is required for product being sent to the factory for repair. An SRA can be completed online at www.crownaudio.

com/support/rma. If you do not have access to the web, please call Customer Service at 574.294.8200 or 800.342.6939 extension 8205 in North America,

Puerto Rico and the Virgin Islands only. For warranty service, we will pay for ground shipping both ways in the United States. Contact Customer Service to obtain prepaid shipping labels prior to

sending the unit. Or, if you prefer, you may prepay the cost of shipping, and HARMAN will reimburse you. Send copies of the shipping receipts to HARMAN to receive reimbursement.

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

GNU General Public License Version 2

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

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

Preamble

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

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

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

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

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

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

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

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

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0� This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms

of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modiﬁcations and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modiﬁcation".) Each licensee is addressed as "you".

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

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

Page 94

CDi DriveCore Series Operation Manual

Page 97

GNU General Public License Version 2

the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2� You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such

modiﬁcations or work under the terms of Section 1 above, provided that you also meet all of these conditions:

a) You must cause the modiﬁed ﬁles to carry prominent notices stating that you changed the ﬁles and the date of any change.

b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be

licensed as a whole at no charge to all third parties under the terms of this License.

c) If the modiﬁed program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the

most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else,

saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of

this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not

required to print an announcement.)

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

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

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

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

a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2

above on a medium customarily used for software interchange; or,

b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing

source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above

on a medium customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for

noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b

above.)

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

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

CDi DriveCore Series Operation Manual

Page 95

Page 98

GNU General Public License Version 2

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

4� You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

5� You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.

6� Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.

7� If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.

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

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

This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8� If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder

who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.

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

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

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

NO WARRANTY 11� BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY

APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

12� IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE

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

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

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

This program is free software; you can redistribute it and/or

modify it under the terms of the GNU General Public License

as published by the Free Software Foundation; either version 2

of the License, or (at your option) any later version.

This program is distributed in the hope that it will be useful,

but WITHOUT ANY WARRANTY; without even the implied warranty of

MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the

GNU General Public License for more details.

You should have received a copy of the GNU General Public License

along with this program; if not, write to the Free Software

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

Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode:

Gnomovision version 69, Copyright (C) year name of author

Gnomovision comes with ABSOLUTELY NO WARRANTY; for details

type `show w'. This is free software, and you are welcome

to redistribute it under certain conditions; type `show c'

for details.

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

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

Yoyodyne, Inc., hereby disclaims all copyright

interest in the program `Gnomovision'

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