3. CONNECTIONS AND CONTROLS
1 INPUT GAIN CONTROL
Input level control potentiometer to adjust the input gain of the active subwoofer to match
with the head-unit output voltage.
2 PHASE
Two position slide switch to adjust the acoustical phase of the bass signal.
3 INPUT LEVEL
Input level control to match the output voltage of the head-unit’s RCA line-outs to the
amplifier input section.
„Lo“ for systems that provide an RCA preamp line out signal to the amp module input.
“Hi” for systems that provide speaker high level signal to the amp module input.
4
AUTO TURN ON
Slide switch with three positions:
“REM” > For aftermarket headunits featuring a REM output (+12V control voltage for amps)
“DC OFFSET” > For offsetbased signal and wiring using high-level inputs of the OE radio.
“AUDIO” > For RCA input but without REM control voltage.
5
REM PORT
Input terminal to connect the cable of the bass level remote control to the amp module.
Connecting the bass level remote to the 3.5mm jack at the amp module will bridge and
thus override the GAIN control.
6 AUDIO INPUT
4-pin Molex connector to plug in the input cable extension – for RCA or High-level stereo
signal input of the amp module.
7 FUSE
Double fuse holder for two single 10A (red) standard automotive ATC fuses. Do not use any
other current rating than 10A (red) if these fuses need to be replaced.
8
POWER BLOCK
Removable power input terminal, for three wires:
“
” > Terminal to connect the power wire to the vehicle chassis ground.
“REM” > Terminal to connect the wire from the REM output of the headunit, when the RCA
preamp audio of the headunit is used to drive the active sub.
“
” > Terminal to connect the power wire to the positive pole of the battery.
9
POWER / PROTECT LED
Status LED signaling the operational status of the amp with two LED colors:
“BLUE” > Amp is ON and ready for bass playback.
“RED” > Amp is on, but has been overheating or another fault condition prevents the amp
from normal operation.
10 BASS BOOST
Control potentiometer to adjust the bass boost in the 40 Hz range. Adjustment range goes
from 0dB (no boost) to 12dB (12times higher amplifier output).
11 X-OVER
The x-over control allows to set the 12dB/Oct. lowpass filter cut-off frequency between 50
Hz and 200 Hz.
