CDi DriveCore Series Operation Manual

Hardware Setup

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.
