CE 4000 Power Amplifi er

•  The amplifi er’s “Power” switch is off.

•  The amplifi er is not plugged into the 

power receptacle.

•  The amplifi er’s high-voltage power supply 

fuse has blown. Return amp to Crown or 
an authorized Crown Service Center for 
servicing.

•  The amplifi er has just been turned on and 

is still in the 4-second turn-on delay.

•  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 deter-
mine 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.

•  No input signal.

•  Input signal level is very low.

•  Level controls are turned down.

•  This is normal operation for your amp.

•  Input signal level is too high. Turn down 

your amplifi er level controls. NOTE: Your 
amplifi er should never be operated at 
a level which causes the Clip LEDs to 
illuminate constantly.
