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.
Note: The following steps apply to each pair of channels on your amplifier.
2.
Sound in one channel only.
Reverse left and right RCA cables at amplifier inputs. Is the sound
now in the opposite channel?
Yes: Reverse the input RCA cables in every product installed BEFORE
your amplifier until the problem is found. Check RCA cables for
open connections. Repair as necessary.
No: Check the speaker or speaker wires of the dead channel and
repair as needed. If speaker and wire are OK, contact your
authorized dealer.
3.
One or both pairs of 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 or gets softer 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. A fan can be added to aid in ventilation.
