5 Troubleshooting
CONDITION: Power indicator is off and power switch is not illu- minated.
POSSIBLE REASON
• The amplifier has lost AC power.
• The amplifier is not plugged into the power receptacle.
•
CONDITION: Thermal indicator is on.
POSSIBLE REASON:
•The amplifier is becoming too hot for safe operation. Allow amplifier to cool. Check for loads less than 2 ohms, and for excessive input levels. Check for proper ventilation.
CONDITION: Power indicator is off and power switch is illumi- nated.
POSSIBLE REASON
• The amplifier’s Power switch is off.
CONDITION: Power indicator is flashing.
POSSIBLE REASON:
•The AC line voltage has dropped below 15% or has risen above 15% of the
rated range.
“Off/Flashing/On” means that the LED can be off, or flashing, or on.
CONDITION: Fault indicator is flashing.
POSSIBLE REASON:
•The amplifier channel has stopped oper- ating. Refer the unit to an authorized Crown Service Center.
CONDITION: Distorted sound.
POSSIBLE REASON:
•Load is wired incorrectly or Output Mode switch in
•Input is overloaded by a signal level that is too high. Turn down your amplifier level controls (Encoders), or turn down the input signal, until the clip light goes out.
Note: If the signal sounds distorted even though the Clip LED is off, the input signal may be distorted before it reaches the amplifier input. Check gain staging and output levels of the mixer or preamp.
