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, REAR, and SUBWOOFER Remote Inputs

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. The remote inputs are all in parallel. Only one is to be used. Use any one of the three remote inputs to turn the amplifier on. Do not connect external 12-volt accessories to these inputs.

3 FRONT, REAR, and SUBWOOFER Input Sensitivity Controls

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

4 FRONT and REAR 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.)
