The SLAVE IN/ MASTER OUT RCA jacks are suitable to connect an additional identical built amplifier in MASTER/SLAVE mode.
Please check the chapter Interconnection Example: MASTER/SLAVE on page 22.
3
The SUB SONIC controller (Subsonicfilter) limits the ultralow and not hearable frequencies of the audiosignal to below, to avoid
a mechanical and electrical overloading on the subwoofer. The cut-off frequency is adjustable from 15 to 55 Hz and depends on
the size of the subwoofer.
6
The BOOST controller defines the bass boost from 0 to 12dB @ 50Hz.
8
The BASS LEVEL CONTROLLER port is for the cable of the enclosed bass remote controller and only to use in the MASTER
mode. With this bass remote controller, you are able to adjust the bass level e.g. out of the driver’s seat. Please use only the
enclosed bass remote controller and cable. The Remote works only in MASTER mode.
The remote operates strictly as a level attenuator. At full clockwise rotation at maximum position the level will be the same as if
the remote was not connected at all. Find at first the desired bass level without the remote and use the remote then as level
attenuator for the bass level.
You find also two LEDs (POWER/PROTECT) on the remote controller. Check #10 for more information.

The LINE IN RCA jacks must be connected with the RCA output jacks of the headunit.
4
The LPF controller (LOW PASS) adjusts the cut-off point of the frequency range to above. The cut-off frequency is
continuously adjustable from 40 Hz to 150 Hz.
5
The PHASE controller allows to adjust the phasing between 0° and 180°. Thereby you are able to adjust the subwoofer
perfect to the vehicle’s acoustics.
POWER/PROTECT (Also located on the supplied Bass Level Controller)
If the POWER LED lights up, the amplifier is ready for operation.
If the PROTECT LED lights up, a malfunction is indicated. Observe in this case the chapter TROUBLE SHOOTING.
10
The LEVEL controller adjusts the input sensitivity of the amplifier to align the audio signal from the head unit.
The input sensitivity is adjustable from 6 Volts (MIN) to 0.2 Volts (MAX).
7
The MODE switch selects the required operation mode of the amplifier.
In the SLAVE-Mode the amplifier works as a SLAVE amp, this means only the audiosignal of the MASTER amp will be amplified.
All controllers on the SLAVE amp are without function and will be assumed by the MASTER amp.
In the MASTER-Mode (Low Pass mode) you are able to limit the frequencies to above with the LOW PASS controller. All
controllers are active. NOTE: By using only one amplifier, the Mode switch must set to the position MASTER.
