BATT REM GND

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.

1Power 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.

2Protection 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.

3Level (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
