Configure The Amp

IMPORTANT:

 Do not connect the speakers to the amplifier until after it has been properly configured for the application.

•  Make certain the building’s AC mains voltage and current ratings are sufficient to deliver full power to all amplifiers being 

installed.

•  Using the supplied AC power cord, connect the IEC end to the IEC connector on the amplifier, then plug the other end to the AC 

mains outlet. 

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.  

•  The amp may automatically power on. If it does not, press the 

POWER

 button to turn the amp on (the power indicator will light 

blue if sufficient mains power is provided).

•  Wait for the amplifier to boot.
•  Once the amplifier has completed the boot sequence, turn the 

ENCODER

 counter-clockwise until all channel level settings in 

the front panel display read -80.0dB.

•  Press the 

MENU

 button.

•  Select the “CONFIGURE AMPLIFIER” option from the menu using the 

ENCODER

•  Select the “GUIDED SETUP” option from the menu. 
•  Select the desired configuration options, making selections with the 

ENCODER

.

WARNING:

 The CDi DriveCore outputs are configured for Low Z operation by default. To prevent speaker damage, make sure 

to properly configure each output for the type of speaker(s) being connected (i.e., Low Z, 70V, or 100V). See the online operation 
manual for more information.

Make Connections

WARNING:

 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.

•  Turn down the level of your audio source. 
•  Connect the audio source to each applicable amp input using the provided 6-pin connectors.
•  Connect the speakers to the amplifier outputs.

See the “Input/Output Wiring” and “Connection Diagram” sections below for reference.

Set Levels

•  Reconnect the AC power cord to the amp, press the 

POWER

 button, then wait for the amp to boot.

•  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.

•  Turn up the amp levels.

a.  To adjust all amp channel levels respectively: From the Home screen, turn the 

ENCODER

b.  To adjust individual amp channel levels: From the Home screen, press the channel 

SELECT

 button for the channel you 

wish to adjust (the channel will become highlighted in the LCD display). Now turn the 

ENCODER

.

INPUT/OUTPUT WIRING

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.

Never connect the output to a power supply, 
battery or power main. Electrical shock may 
result.
WARNING: The third prong of the AC connector 
(ground) is an important safety feature. Do not 
attempt to disable this ground connection by 
using an adapter or other methods. 

Balanced Input Wiring

Unbalanced Input 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. 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.

NOTE:

 The Crown-designed output cover 

does not need to be removed to connect the 
output wiring.
