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
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
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.
