1 “+12V” POWER INPUT TERMINAL
Power input terminal to connect the active sub to the po12V power wire connected
to the car battery.
2 “REMOTE” INPUT TERMINAL
Terminal to connect the active sub to the amp (remote) turn-on / turn-off lead of the
head unit.
3 “GND” POWER INPUT TERMINAL
Power input terminal to connect the amplifier to the negative or ground wire connected

5 HIGH LEVEL INPUT
Port to connect the high level input adapter to headunits that only offer loudspeaker
outputs, but no RCA line-level outputs.
6 RCA LINE LEVEL INPUT
RCA input to connect the active sub to the line-out of the head-unit (sub-out).
7 AUTO-SENSE SWITCH
If your headunit does not have a "REM" output, you can automatically turn on/off
the amp-modul with the signal of the "HIGH LEVEL" input. Therefore please set the
"SWITCH" to ”ON”.
8 PHASE SHIFT CONTROL
Phase control potentiometer for the relative phase adjustment of the active sub, to match
the acoustical phase of the bass output with other speakers installed in the vehicle.
9 BASS BOOST CONTROL
"BASS BOOST" control potentiometer to add more output in the 60Hz region.
10 CROSSOVER FREQUENCY CONTROL
Crossover control potentiometer to adjust the lowpass frequency of the electronic
crossover with 12dB/oct. between 80 to 200Hz.
11 INPUT GAIN CONTROL
Input level gain control potentiometer, allowing to match the output voltage of the head-
unit’s RCA line-outs to the amp-module input of the active sub.
12 POWER / PROTECTION LED
Blue LED signalling correct operation of the amp module, red (“protection”) LED,
signaling general malfunction of the amp-module, i.e. overheating, shortcut a.s.o.
