OPERATION
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.
1
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 rec12 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
temperature, 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
control 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 of the respective channels
to increase the output from the system. If, however,
there is still output from the amplifier when the car stereo
volume control is at its minimum setting, or the output
level increases too fast with a small rotation of the
