BASIC TROUBLESHOOTING

1.

Amplifier has no output.

Is LED (located on power/ground endpanel) lit?

Yes:

Make sure audio signal is present at RCA inputs. If no signal is

present, use alternate signal source and try again. If signal is
present, check configuration of crossovers. If still no signal, contact
your authorized dealer.

No:

Check power, ground and remote wire for +12V. Verify all

connections. If voltages are correct and still no LED, contact your
authorized dealer.

2.

Speakers sound distorted when playing music.

Check to make sure all RCA and speaker wire connections are good
and tight.  Make sure gains are not turned up above clipping.

3.

The amplifier channels “squeal” when operating.

One or more speaker wires are shorted or one or more speaker
voice coils are shorted or rubbing. If speakers and wires are OK,
contact your authorized dealer.

4.

Amplifier volume cuts out as music is playing without touching
any system controls.

Amplifier is going into thermal protection. Make sure amplifier has
room to breathe. Preventing air from reaching the heatsink will
cause the amplifier to overheat, as will running the amplifier at too
low of an impedance.
