Protect - LED
Red LEDis illuminated:
a) Overheated
b) Speaker wires shorted
c) Overload (Impedance, less Power)
d) Amplifier is damaged
Should the amplifier go into proteciont mode, simply disconnect
all RCA and speaker leads, while keeping +12 volt, power ground
and remote leads connected. Now turn the amplifier back on, and
if the PROTECT-LED lights, the amplifier has an internal fault.
If not, plug the RCA cables back, and reset the amplifier. If it goes
into protection mode now, the fault lies in the input, either with
bad cables or source unit.
If the amplifier seems fine with RCA cables plugged in, connect
the speakers, one at a time, and if one of the speakers or its
wiring is faulty, it will activate the diagnostic
system.
