Commercial Mixer Amplifier

Troubleshooting
CONDITION: No power to the mixer amplifier.
POSSIBLE REASON:
• The mixer amplifier’s power switch is Off.
• The mixer amplifier is not plugged into the AC power receptacle.
• The mixer amplifier’s high-voltage power supply circuit breaker has tripped.
Verify that the AC mains voltage is correct.
CONDITION: Distorted sound.
POSSIBLE REASON:
• Input signal level is too high. Turn down the input level controls.
NOTE: The mixer-amplifier should never be operated at a level which causes the Clip LEDs to
illuminate constantly.
• Master volume level is too high. Turn it down to about
3
/4 of maximum level.
CONDITION: No sound.
POSSIBLE REASON:
• The amplifier is in “fault” mode. A Fault status can be triggered when one of the amplifier’s
protection circuits is activated. First disconnect your loudspeakers from the affected channel(s) one by
one to determine if one of the loads is shorted. If an amplifier channel has a thermal fault, there will
be no indication on the front panel, but the amp will recover after cooling. If operation does not return
to normal after restarting the amplifier, contact AtlasIED at 1-800-876-3333.
POSSIBLE REASON:
• No input signal.
• Input signal level is very low.
