Control Functions
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.
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.
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.
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.)
