CE 4000 Power Amplifier

6 Troubleshooting

CONDITION: Normal operation.

POSSIBLE REASON:

• This is normal operation for your amp.

CONDITION: No power to the amplifier.

POSSIBLE REASON:

• 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.

CONDITION: Distorted sound.

POSSIBLE REASON:

• 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.

KEY

CONDITION: No sound.

POSSIBLE REASON:

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.
