1 HIGH INPUT
Molex connector terminals to insert the High level adapter (2 x 4-pin) that picks up
the amplified speaker signal from the head unit’s front output (if head unit does not
feature dedicated RCA line outs).
2 SUM ACTIVATION SWITCH
The sum function combines the CH1+3 and CH2+4 input channels.
If the car stereo provides only speaker dedicated signals (i.e. high frequencies only
for tweeter and second output with only low frequencies for the midrange/woofer), this
sum function combines both signals to one complete full range signal.
3 RCA INPUTS
Low-level stereo RCA signal input for connection to head-unit.
4 INPUT GAIN CONTROL 1/2-CH
Input gain potentiometer for channel 1/2-CH, to match the output voltage of the head-
unit to the amplifier’s input.
5 X-OVER ACTIVATION SWITCH 1/2-CH
Switch to de-/activate the crossover filtering section of the amplifier.
6 X-OVER MODE 1/2-CH
Switch to choose between high- and lowpass filtering.
7 X-OVER FREQUENCY CONTROL 1/2-CH
Control potentiometer to adjust the crossover filtering frequency point of the amplifier.
8 X-OVER FREQUENCY CONTROL 3/4-CH
Control potentiometer to adjust the crossover filtering frequency point of the amplifier.
9 X-OVER MODE 3/4-CH
Switch to choose between high- and lowpass filtering.
10 X-OVER ACTIVATION SWITCH 3/4-CH
Switch to de-/activate the crossover filtering section of the amplifier.
11 INPUT GAIN CONTROL 3/4-CH
Input gain potentiometer for channel 3/4-CH, to match the output voltage of the head-
unit to the amplifier’s input.
12 SUM BALANCE CONTROL
Potentiometer to adjust the right volume balance between CH1 and CH2.
13 POWER LED
LED to show proper operating status of the amplifier by green illumination. Protect
state of amplifier is signaled by the red LED.
14 “GND” POWER INPUT TERMINAL
Terminal to connect the amplifier to the chassis ground or negative pole of the car
battery.
15 “REM” INPUT TERMINAL
Terminal to connect the amplifier to the automatic (remote) turn-on / turn-off lead of the
head unit.
