After initial set-up, the amplifier should not require any
further adjustment unless there is a change in the car
stereo or speaker system with which it is used.

Power Indicator Lamps
The Power Indicator Lamps will light to indicate that the unit
is connected to the battery and that the Remote
Turn-On terminal is receiving +12 volts, thus turning on the
amplifier.
2
Protection Mode LED
This LED illuminates red to indicate that the self-protection
circuits have been activated and have shut off operation of
the amplifier. The protection circuits may be triggered
by the temperature of the unit rising above a safe level
or by an overload condition.

If activated by a rise in emperature, the unit will resume
operation after cooling off to a normal operating range.
If activated by an overload condition, the source of the
overload must be found and corrected to resume
operation of the amplifier.
Most overload conditions are caused by mis-wiring or
operation into incorrect speaker loads. Re-check all
wiring and connections if this situation occurs and
correct as necessary.
Level (Gain) Controls

The amplifier is capable of operating from sources
supplying a wide range of input levels. The Level controls
should initially be set to the mid-rotation position.
If it is found that there is not enough output even when
the volume control on the car stereo is at its maximum
setting, adjust the Level control to increase the output
