Wiring Input Connectors
Crown recommends using pre-built or professionally wired balanced cables (two-conductor plus shield). Balanced wiring provides better rejection of unwanted noise and
hum; however, unbalanced line may also be used.
Use 6-pin plug-in cable ends at the amp input connectors. A male connector is supplied for each input of your model of amplifier. Additional connectors are available from
Crown (P/N 5024623).
Figure 3 shows connector pin assignments for balanced wiring and Figure 4 shows connector pin assignments for unbalanced wiring. Note that for bridged operation,
only the odd-numbered input channels (1,3,5,7) should be wired for each bridged pair.
For Dante audio connections, standard Category 5e or 6 Ethernet cabling should be used for Gigabit networks. Category 5 cabling can be used for 100Mbps network
connections. Primary and Secondary Dante ports are provided; Dante audio traffic is duplicated to both of these ports. The Secondary port can be connected to a second
network switch for redundant operation in the event the Primary cable connection or switch is compromised.
Figure 3: Balanced wiring Figure 4: Unbalanced wiring
Wiring Output Connectors
IMPORTANT: The amplifier output mode (Low Z, High Z) should be properly configured for the application before connecting the speakers. By default, all outputs are
configured for Low Z operation. See "Hi-Z/Low-Z" on page 15 for more information.
Before making any output connections, ensure the power cord is disconnected from the amplifier and carefully review the total impedance for loudspeakers connected to
each amplifier output. If multiple loudspeakers are connected to an output in Low Z mode (i.e., in series, parallel, or series-parallel), be certain the total system impedance
is within allowed specification for the output. When multiple loudspeakers are connected to one output in High Z mode, be certain total tapped power is below the rated
power output for the channel. See "DCi DA Specications" on page 47 for supported load specifications.
NOTE: Crown has designed an output cover that does not need to be removed to connect the output
wiring.
Crown recommends using the included spade connectors and two or four-conductor, heavy gauge
speaker wire. You may use terminal forks up to 10 AWG or bare wire for your output connectors (see
Figure 5). For best results, Crown recommends Panduit part #PV10-6LF-L or equivalent terminal
fork. For bare wire, it is highly recommended that output wiring is tinned. To reduce strain on input and
output wiring, Crown recommends the use of horizontal lacer bars. For best results, Crown recommends
Middle Atlantic part# LBP-4R90 or equivalent horizontal lacer bar.
For low-impedance loads, select the appropriate size of wire based on the distance from amplifier to
speaker.
Distance Wire Size
Up to 25 ft. (7.6m) 16 AWG
26-40 ft. (7.9-12.2m) 14 AWG
41-60 ft. (12.5-18.3m) 12 AWG
> 60 ft (18.3m) 10 AWG
CAUTION: Never use shielded cable for output wiring.
CAUTION: Never connect the speaker return to the chassis of the amplifier, or damage to the amplifier may result.
NOTE: Custom wiring should only be performed by qualified personnel. Class 2 output wiring is required.
For application-specific output connection diagrams, including how to wire outputs for bridge mono operation, see "Application Examples" on page 18.

DriveCore Install DA Series Operation Manual
Precautions
Connecting Network Cables
When making connections to the control network and Dante ports, the included ferrites should be attached
to the network and Dante cables at the back of the amplifier as shown in Figure 6. Both a small and large
ferrite should be attached to each cable as shown.
Connecting to AC Mains
Connect your amplifier to the AC mains power source (power outlet) using the supplied AC power cord set.
First, connect the IEC end of the cord set to the IEC connector on the amplifier; then, plug the other end of the
cord set to the AC mains.
WARNING: The third prong of this connector (ground) is an important safety feature. Do not
attempt to disable this ground connection by using an adapter or other methods.
Make certain the AC mains voltage and current ratings are sufficient to deliver full power to all amplifiers.
If the AC line voltage varies out of an acceptable range, the amplifier’s power supply turns off and the blue
Power LED flashes. The amplifier will turn back on when the AC line voltage returns to safe operating levels.
DriveCore Install DA amplifiers utilize a universal power supply. The AC voltage requirements are
100V-240V~, 50/60Hz (±10%). If the voltage exceeds these requirements, the Power LED will flash and the
amplifier will stop passing audio until the voltage is within the requirements.
Startup Procedure
When first turning on your amplifier:
1� Turn down the level of your audio source.
2� Turn on the “Power” switch. The Power indicator should light.
3� Turn down the amplifier levels in Audio Architect, see "Channel Levels and Mutes" on page 35.
4� Turn up the level of your audio source to an optimum level. Ensure that at no point in the signal chain is the signal being clipped in any way.
5� In Audio Architect, turn up the amplifier levels to the desired level.
Precautions
Your amplifier is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety:
2� Use care when making connections, selecting signal sources, and controlling the output level. The load you save may be your own!
3� Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and cause oscillations.
4� Never connect the output to a power supply, battery, or power main� Electrical shock may result�
5� Tampering with the circuitry or making unauthorized circuit changes may be hazardous and invalidate all agency listings.
6� Do not operate the amplifier with the Clip LEDs constantly flashing.
7� Do not overdrive the mixer, which will cause clipped signal to be sent to the amplifier. Such signals will be reproduced with extreme accuracy, and loudspeaker
damage may result.
8� Do not operate the amplifier with less than the rated load impedance. Due to the amplifier’s output protection, such a configuration may result in premature clipping
and speaker damage.
REMEMBER: Crown is not liable for damage that results from overdriving other system components.

Software Setup
Software Setup
Setup and configuration of the DriveCore Install DA Series amplifiers can be completed through HiQnet Audio ArchitectTM. The amplifier should be connected to a TCP\
IP network via the Ethernet connection on the back of the amplifier. Note that the Dante digital audio transport connectors cannot be used for control and monitoring of the
amplifier.
To quickly configure your DriveCore Install DA amplifier, connect all of the amplifiers and configuration computer to the same network. For more information on network
configuration, please visit http://audioarchitect.harmanpro.com. In the following example, we will only show amplifiers.
When Audio Architect is first loaded, the software will scan the network for HiQnet devices. All devices that are discovered on the network will be found under the ADD
DEVICES tab on the left hand tree menu. If the devices are not found, then the network may not be configured correctly. See Figure 7.

The NetSetter Grid
The NetSetter grid is divided into the 12 sections described below.
Figure 10: 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, Dante card MAC address, etc.), the field will be
represented as a dropdown menu and the desired MAC address can be selected from the list. For a device connected to the same control network with two control
MAC addresses, the MAC address field will be displayed in red.
2� DHCP/Auto-IP
If the discovered device is configured to use DHCP/Auto-IP, this checkbox will be checked. If the discovered device is not using DHCP/Auto-IP, you may check the box
so it will do so on applying edits. The device row will then become selected. The device will attempt to have its IP settings configured by DHCP on applying the edits;
if no DHCP server is present, the device will attempt to have IP settings configured by Auto-IP.
All devices in the current filter view may be configured with DHCP/Auto-IP enabled by checking the checkbox in the column header—the individual checkboxes
for all devices will become checked. If a single individual checkbox for a device is subsequently unchecked, the column header DHCP/Auto-IP checkbox will be
automatically unchecked. Conversely, all devices in the current filter view can be configured with DHCP/Auto-IP disabled by unchecking the checkbox in the column
header.
DHCP server status will be among the information displayed at the bottom of the NetSetter window. If a DHCP server is not detected, the information will read "DHCP
server not detected". Note that checking a device’s DHCP/Auto-IP checkbox has no immediate effect on the column sort order.
NOTE: Once edits have been made, it is critical to click the Apply Current Edits or Apply and Exit buttons for the changes to take affect.
3� IP Address
Displays the IP address of the discovered device. A valid IP address may be edited inline. If the edited value scopes the device out of the current Display filter, it will
not be visible.
NOTE: A discovered device with an IP address that conflicts with that of another, already discovered device will be displayed in red. A conflicting IP address may be
edited inline if you wish to change the device IP address on applying current edits. If DHCP/Auto-IP is enabled, the IP address field may not be edited inline.
NOTE: Once edits have been made, it is critical to click the Apply Current Edits or Apply and Exit buttons for the changes to take affect.
4� Subnet Mask
Displays the Subnet Mask of the discovered device. The Subnet Mask may be edited inline. The device row will be ordered accordingly with the current column sort
immediately on successful editing of the field. The device row will remain selected.
NOTE: If DHCP/Auto-IP is enabled, the Subnet Mask field may not be edited inline.
NOTE: Once edits have been made, it is critical to click the Apply Current Edits or Apply and Exit buttons for the changes to take affect.
5� Default Gateway
Displays the Default Gateway of the discovered device. The Default Gateway may be edited inline. The device row will be ordered accordingly with the current column
sort immediately on successful editing of the field. The device row will remain selected.
NOTE: If DHCP/Auto-IP is enabled, the Default Gateway field may not be edited inline.

page 10 DriveCore Install DA Series Operation Manual
Conguring the Network using NetSetter
If the device is being rediscovered, then the following behavior will occur:
• When the device is not selected, the device Default Gateway address field is displayed but is grayed out.
• When the device is selected and highlighted in orange, the field is represented in dark gray.
NOTE: Once edits have been made, it is critical to click the Apply Current Edits or Apply and Exit buttons for the changes to take affect.
6� Device ID
Displays the HiQnet address of the discovered device. This field may be edited inline if you want to change the device HiQnet address. If the edited value scopes
the device out of the current Display filter, it will not be visible and no devices will be selected. If devices are discovered with a conflicting HiQnet address, then the
following will occur:
• The HiQnet ID field of a discovered device will be displayed in pink when a HiQnet address conflicts with that of another, already discovered HiQnet address.
• When the device is selected and highlighted in orange, the field is represented in red.
• The HiQnet address is not displayed, instead a dash is displayed as grayed out.
NOTE: A conflicting HiQnet address may be edited inline if you want to change the device HiQnet address.
NOTE: Devices are not discoverable at the IP level. A device which is not discoverable at the IP level (invalid IP address, etc.) will not be able to report a HiQnet
address. In this instance, the HiQnet ID field will display a "?" to indicate that the field may exist but that the software does not have enough discoverability of the
device to determine the value. A blank field or "-" implies the value is null and the HiQnet ID field may not be edited inline.
NOTE: Once edits have been made, it is critical to click the Apply Current Edits or Apply and Exit buttons for the changes to take affect.
7� Random ID Reboot
When enabled, the device will be given a random HiQnet address. If you want to set the HiQnet address of a device to a random ID, check the Random ID checkbox. If
the checkbox is unchecked before applying current edits, the prior HiQnet ID value will be restored.
All devices in the current filter view may be set to Random HiQnet ID by checking the checkbox in the column header—the individual checkboxes for all devices will
become checked. If any individual checkbox is subsequently unchecked, the column header Random ID checkbox will automatically be unchecked. Conversely, if all
devices in the current filter view are set to Random ID on and the Random HiQnet ID column header checkbox is checked, all devices may be set to Random ID off by
unchecking the column header checkbox—the individual checkboxes for all devices will become unchecked.
NOTE: Devices are not discoverable at the IP level. A device which is not discoverable at the IP level (invalid IP address, etc.) will not be able to report a HiQnet
address. In this instance, the Random ID checkbox will be unavailable.
8� Status
Displays the current discovery status of the device. The Status field may not be edited. Discovery status hierarchy is as follows:
a� Discovered
If a device has a unique IP address and a unique HiQnet address, this condition will be shown unless the device is access controlled. When the device is not
selected, the "Discovered" label is represented in green.
The "Discovered" status is determined by the following conditions:
• The device is discoverable at the MAC address level.
• The device has a valid and unique IP address (manual or DHCP/Auto-IP).
• The device has a unique HiQnet address.
• The device is not access controlled.
b� IP Conflict
If a device has an IP address conflict, this error will be shown regardless of other status notifications. When the device is not selected, the "IP conflict" label is
represented in blue.
The "IP conflict" status is determined by the following conditions:
• The device is discoverable at the MAC address level.
• The device has an IP address that conflicts with another device which has already been discovered by NetSetter.
c� HiQnet Conflict

page 11
DriveCore Install DA Series Operation Manual
Conguring the Network using NetSetter
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

page 12 DriveCore Install DA Series Operation Manual
Conguring the Network using NetSetter
running an instance of HiQnet software. HiQnet software programs include System Architect, Audio Architect, and Performance Manager.
TIP: A selected device may have its Venue Data cleared (including all Building, Floor, and Room Venue data) by pressing the Clear Container button. This action
takes place on applying current edits only and can be undone with the Undo Current Edits button.
NOTE: The Container/Position Venue Data may not be edited inline.
NOTE: Devices are not discoverable at the IP or HiQnet level. A device which is not discoverable at the IP level (invalid IP address, etc.) or HiQnet address level
(HiQnet address conflict, etc.) will not be able to report its Container : Position data. In this instance, the Container : Position field will display a "?" to indicate that the
field may exist but that the software does not have enough discoverability of the device to determine the value. A blank field or "-" implies the value is null.
12� Locate
The Locate feature allows a device to be easily identified within a network full of HiQnet devices. Clicking in the Locate column for a device will put the corresponding
networked device into a Locate state—the Locate icon will be displayed on-screen and something will happen on the device to indicate the Locate state is active (e.g.,
an LCD or LED will flash, etc.). Clicking an active Locate icon will disable the Locate state for the device. Disabling the Locate state from the device will clear the icon.
Devices may be put into a Locate state independently from selection so that more than one device can be located at any one time.

Offline/Online Operation Explained
Offline/Online Operation Explained
Audio Architect has two define modes of operation: Offline and Online. Offline operation allows the system to be configured without real time changes to the system. In this
mode, changes have to be sent to the edited device. In Online mode, changes to amplifiers are made real time.
When Audio Architect first opens, the Offline Design Tab is the ribbon presented, and the Device Toolbox appears on the left and an empty Properties window is at the
bottom. The Add Devices box is highlighted. When going Online, it may be necessary to Match Devices and/or Synchronize Venue.
Figure 11: Main Audio Architect window
Match Devices allows users to associate amplifiers within their venue design to amplifiers on the network.
Figure 12: Match Devices ribbon
In the Match Devices tab, the following options are available:
• Networking
Clicking the Refresh button will temporarily take Audio Architect offline, then restart the network.
• Match
Clicking the Auto-Match Venue button will automatically match devices on the network with the devices in the Audio Architect venue. Selecting a device then
clicking the Detach button removes the device's virtual connection with Audio Architect.
• Editing
Clicking the Undo button will undo the last change made and revert back to the previous state. Clicking the Redo button will redo the last action that was undone.
• Show
Any checked items in this section will be displayed alongside the appropriate devices in the Main Audio Architect window. The available items include Device Names,
Rack/Array Names, HiQnet Addresses, IP Addresses, Matched Indicator, and Unmatched Indicator.
When going Online, the following options are possible:
• If one or more devices in the Venue are not matched AND corresponding devices are available on the network, going online lands in Match Devices mode.
• If all the devices in the Venue are matched, going online lands in Synchronize Venue mode. In Synchronize Venue mode, the user is given the option to either Send
data from Audio Architect to the device or Receive data from the device to Audio Architect.
• If no devices require to be synced, going online lands in Run Venue mode.

Offline/Online Operation Explained
Each amplifier can be dragged into the room window. Each device will have an IP address listed on the left of the amplifier and a Name ID on the right of the amplifier. The
Name ID can be edited in the properties menu at the bottom of the window. The number to the left of Name ID is the HiQnet Device Address. The green circle only indicates
that the amplifier has been discovered on the network.
The small box located below the rack allows quick access to
amplifier factory panels. These panels include the following
items:
• Factory Master Panels
• Monitor Panels
• Meter Panels
• Level and Mute Panels
NOTE: When a device is added to the window, it is automatically
removed from the "Discovered" section.
Double clicking an amplifier will access the amplifier factory control panel. At this point, Audio Architect is in OFFLINE MODE. In OFFLINE MODE, amplifier changes are
not made in real time and will need to be sent to the amplifiers. Amplifier changes can also be sent in real time in ONLINE MODE. To go to ONLINE MODE, click on the GO
ONLINE tab in the Workflow bar menu. RECEIVE and SEND buttons will appear for each device, rack, and room in the design. This gives the user the option to just update a
single device, all devices in a rack or an entire venue. Click SEND to load the settings made in Audio Architect to the amplifier. Click RECEIVE to read the settings off of the
amplifier to be reflected in Audio Architect.

Cascading Inputs
Cascading the analog inputs, or "Y-ing channels", gives more flexibility to the installation of a DCi DA amplifier (See Figure 17). One input can be used to drive some or
all of the amplifier outputs.
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 (See
Figure 18).
