4 Troubleshooting
Problem: Power indicator does not turn on.
Procedure:
Check that the amplifier is plugged into a live outlet. After
you have ensured that it is not a power issue, disconnect any speakers.
If the amplifier turns on after a few seconds delay, then the problem is
in the output connection. Check wiring and speakers for short circuits.
Problem: No output on one or both channels; 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
flashing 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 signal lights on the rear of the amplifier to see if the signal is over-
driving (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.
