Symptom:
Recommended Action:
No output Power indicator is off.
(There is a normal delay of up
to 30 seconds on turn-on.)
Be sure power outlet is “live” Be
sure power switch is “on.”
No output Power indicator LED
cycles on and off.
This indicates a short-circuit
condition on the output. Discon-
nect speaker wires and turn
amplifier power switch on. If
amp stays on, the problem is in
the output wiring or speakers.
Power indicator on; no output
from one or more channels.
Check input level controls, input
and output cables, input signal
and speakers.
Low volume in one or more
channels.
Check input level controls, input
wiring and input signal levels.
Be sure speakers are the same
impedance.
Amplifier overheats and/or
shuts off.
Review section on Thermal
Considerations. Check clip lights
for indication of overdriving.
(NOTE: overdriving for a long
period of time can cause
thermal shutdown.)
Distorted output.
Check input signal level and
signal source. (Set gain by
turning amplifier volume all the
way down, set preamp level to
normal, turn up amplifier
volume to desired level.)
Noise on output.
Check signal source for noise.
Long unbalanced lines can
cause noise, change to balanced
lines. (See set gain above.)
