5 Troubleshooting
CONDITION: Normal operation. 
•  This is normal operation for your amp.
CONDITION: No power to the amplifier. 
  
•  The amplifier’s Power switch is off.
•  The amplifier’s power cord is unplugged.
CONDITION: Distorted sound.
•  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.
•  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 
channels(s) one by one to determine if one of the loads is 
shorted. If the indicators return to normal status, 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.
