1 FRONT RCA Inputs

RCA cables marked “FRONT” from head unit or from other line level device

should be connected here. Use both inputs (L & R) for stereo.

2 FRONT Remote Input

Use the supplied FEMALE quick connector to connect the REMOTE trigger lead from the head unit to the amplifier. Amplifier turns “ON” when head unit is turned “ON.” One FEMALE .210" connector is supplied with amplifier.

3 FRONT Input Switch

In the left position, the L & R inputs go to the FRONT L & R channels of the ampli- fier. In the right position, the L & R inputs go to the FRONT and REAR L & R chan-

nels of the amplifier.

4 FRONT and REAR Sensitivity

Turn control clockwise to increase the amplifier sensitivity to incoming signals. Turn

control counterclockwise to decrease the amplifier sensitivity.

5 FRONT Highpass Crossover Controls

To use 12dB/octave crossover, move switch to right-hand position. Highpass crossover frequency is adjustable from 20Hz to 350Hz by rotary control. (Moving switch to left-hand position will bypass crossover functions.)
