• The amplifier has lost AC power.
• The amplifier's Power switch is off.
• The amplifier's power cord is not plugged in at
either end.
• The amplifier's circuit breaker has tripped.
Allow the amplifier to cool; remove excessive
loads, and press the reset switch on the front
panel.
CONDITION: No input signal (Signal indi-
cator is not flashing even though audio is applied).
POSSIBLE REASON:
• Input signal level is very low.
• Master audio from mixer turned down.
• Input cable broken or not plugged in.
CONDITION: Fault indicator is
flashing.
POSSIBLE REASON:
• .The amplifier has just been turned on and is
still in the 4-second turn-on delay.
• The heatsinks are too hot.
• The transformer thermal protection is activated.
• The amplifier output wires have developed a
short circuit.
• The amplifier output stage has stopped operat-
ing. Refer the unit to an authorized Crown Ser-
vice Center
The fault status of the amplifier can also be moni-
tored remotely by attaching a signal device to the
Fault jack located on the amplifier back panel. See
the Advanced Features and Options section for more
detail.

CONDITION: Distorted sound.
POSSIBLE REASON:
• Load is wired incorrectly or Stereo/Mono
mode switch is set incorrectly. Check both.
• Input signal level is too high. Turn down your
amplifier level controls, or turn down the input
signal, until the clip LED goes out.
Note: If sound is distorted but clip LED is not flash-
ing, check mixer levels and gain staging, mixer clip
lights, and pads built into microphones.
CONDITION: Input signal but no
sound.
POSSIBLE REASON:
• Speakers not connected. Make sure the Neutrik
NL4 connector is fully seated and locked.
• The amplifier output level is so high that the
breaker has tripped. Try to identify and correct
the problem before resetting the breakers. If
the problem persists, refer the unit to an autho-
rized Crown Service Center.
