CONDITION: No power.

POSSIBLE REASON:

• The mixer-amplifier’s Power switch is off.

• The mixer-amplifier is not plugged into the power receptacle.

• The mixer-amplifier’s high-voltage power supply circuit breaker has tripped. Verify that the AC mains voltage is correct, then press the Reset button on the back panel.

CONDITION: Distorted sound.

POSSIBLE REASON:

• Input signal level is too high. Turn down your input volume controls. NOTE: Your mixer- amplifier should never be operated at a level which causes the Clip LED to illuminate constantly.

• Master volume level is too high. Turn it down to about 3/4 of maximum level.

CONDITION: No sound.

POSSIBLE REASON:

The amplifier is in “fault” mode. A Fault status can be triggered when one of the amplifier’s protection circuits is activated. First disconnect your speakers from the affected channel(s) one by one to determine if one of the loads is shorted. If an amplifier channel has a thermal fault, there will be no indication on the front panel, but the amp will recover after cooling. If operation does not return to normal after restarting your amp, press the Reset button on the back panel, or return mixer-amp to Crown or an authorized Crown Service Center for servicing.

• No input signal.

Input signal level is very low.
