Operation Manual
CONDITION: Power indicator is off.
POSSIBLE REASON
• 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.
• Front-panel Level controls are turned down.
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
Section 4.2.2 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.
