Operation Manual
CONDITION: No power.
POSSIBLE REASON:
The mixer-amplifi er’s Power switch is off.
The mixer-amplifi er is not plugged into the 
power receptacle.
The mixer-amplifi er’s high-voltage power 
sup ply 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- 
amplifi er should never be operated at a level 
which causes the Clip LED to illuminate 
con stantly.
Master volume level is too high. Turn it down to 
about 3/4 of maximum level.
CONDITION: No sound.
POSSIBLE REASON:
The amplifi er is in “fault” mode. A Fault status 
can be triggered when one of the amplifi er’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 amplifi er 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 
ser vicing.
