4 Troubleshooting
Problem: Power indicator does not turn on.
Procedure:
Check that the unit’s power supply is plugged into a func-
tioning outlet and the power supply is correctly connected to the unit.
Ensure that there is an audio signal present on the audio input indicated
by the green LED being lit. If the unit is powered up but in sleep mode
(due to no signal), the blue power LED will not be lit.
Problem: No output heard on speakers; Blue power indicator is lit.
Procedure:
Check that level controls are not turned down. Check that
input and output connections are secure. Ensure signal present LED is
lit to denote a signal. If there is no signal detected check signal source
and that level controls are set high enough.
Problem
:
Amplifier overheats and/or shuts off.
Procedure:
Review
section 2.3
on proper cooling procedures. Check
the clip LED on the rear of the amplifier to see if the signal is overdriv-
ing (the signal light flashes red frequently). Overdriving the amplifier for
extended periods of time can cause a thermal shutdown.
Problem: Output sound is distorted or cracking.
Procedure:
Check all cables for damage or loose connections and re-
duce the gain on the input signal at the mixer or preamp level. Replace
the cables and loudspeakers temporarily to see if this resolves the
problem. If problem still exists, contact your Authorized Dealer for ser-
vice.
