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 "Conguring the Amp" on page 11 for more information.
Connect your amplifier to the AC mains power outlet using the supplied AC power cord. First, connect the IEC end of the cord to the IEC connector on the
amplifier. Then plug the other end of the cord to the AC mains.
WARNING: The third prong of the power connector (ground) is an important safety feature. Do not attempt to disable this ground connection
by using an adapter or other methods.
Make certain the AC mains voltage and current ratings are sufficient to deliver full power to all amplifiers. CDi DriveCore Series amplifiers use a universal
power supply. The AC voltage requirements are 100V-240V~, 50/60Hz (±10%). If the AC line voltage varies outside of this acceptable range, the amplifier’s
power supply will turn off and the blue Power LED will flash. The amplifier will turn back on when the AC line voltage returns to safe operating levels.
Power Up Procedure
When turning on the amplifier for the first time:
1� Ensure all connections are disconnected with the exception of the power cord.
2� Press the amplifier's POWER button. The Power indicator will light blue and the amplifier will boot as long as sufficient mains power is provided.
3� Once boot up is complete, turn the ENCODER counter-clockwise until all amp levels are set to -80dB in the front panel LCD.
4� Configure the amplifier as described in "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.
IMPORTANT: Always turn off the amplifier — by pressing and holding the Power button for 2 seconds — and disconnect the power cord before making
any wiring or installation changes.
IMPORTANT: When powering a fully configured PA system, always turn the amplifiers on last and off first.
For help with determining your system’s optimum gain structure (signal levels) please refer to the Crown Amplifier Application Guide, available online at
www.crownaudio.com.

Precautions
Your amplifier is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety:
1� Configure the amplifier for proper operation, including input and output wiring hookup. Improper wiring can result in serious operating difficulties.
For information on wiring and configuration, please consult "Wiring Input Connectors" and "Wiring Output Connectors" on page 7.
For advanced setup techniques, consult Crown’s Amplifier Application Guide available online at www.crownaudio.com.
2� Use care when making connections, selecting signal sources, and controlling the output level. The load you save may be your own!
3� Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and cause oscillations.
4� Never connect the output to a power supply, battery, or power main� Electrical shock may result�
5� Tampering with the circuitry or making unauthorized circuit changes may be hazardous and invalidate all agency listings.
6� Do not operate the amplifier with the Clip LEDs constantly flashing.
7� Do not overdrive the mixer, which will cause clipped signal to be sent to the amplifier. Such signals will be reproduced with extreme accuracy, and
loudspeaker damage may result.
8� Do not operate the amplifier with less than the rated load impedance. Due to the amplifier’s output protection, such a configuration may result in
premature clipping and speaker damage.
REMEMBER: Crown is not liable for damage that results from overdriving other system components.

Wiring Input Connectors
Crown recommends using pre-built or professionally wired balanced cables (two-conductor plus shield). Balanced wiring provides better rejection of
unwanted noise and hum, however, unbalanced line may also be used.
Use 6-pin plug-in cable ends at the amp input connectors. A male connector is supplied for each input of your model of amplifier. Additional connectors
are available from Crown (P/N 5024623).
Figure 4 shows connector pin assignments for balanced wiring and Figure 5 shows connector pin assignments for unbalanced wiring. Note that for
bridge mono operation, only the odd-numbered input channels (1,3) should be wired for each bridged pair.
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 66 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.
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
45.

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.
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 51 for more information).
• BLU link Output Channel 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 Output Source 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 35.
