5 Troubleshooting

CONDITION: Normal operation.

POSSIBLE REASON:

• This is normal operation for your amp.

CONDITION: No power to the amplifier.

POSSIBLE REASONS:

• The amplifier’s Power switch is off.

• The amplifier’s power cord is unplugged.

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

CONDITION: Distorted sound.

POSSIBLE REASON:

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

CONDITION: No sound.

POSSIBLE REASONS:

•The amplifier has just turned on and is still in the 4-second turn-on delay.

•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 the indicators return to normal sta- tus, then try a different speaker or cable to determine where the short is occurring. If no short can be found, turn off the amp and allow the amp to cool. If indicators do not return to normal after restarting your amp, check the fuse and replace if necessary, or return amp to Crown or an authorized Crown Service Center for servicing.

•Channel is in thermal protection.

•No input signal

•Input signal level is very low.

•Level controls are turned down.

•Speakers not connected.
