4 Troubleshooting
Problem: Power indicator does not turn on.
Procedure: Check that the amplifier is plugged into a live outlet and
that the power switch is in the down position 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. Check that the mode switch
(Stereo, Mono, Bridge) is in the correct mode.
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.
If after reading this troubleshooting section you are unable to restore
proper function, return it to your Authorized Dealer for service. Refer to
section 6 for instructions.
