The MODE switch selects the required operation mode of the amplifier.

In SLAVE-Mode the amplifier works as a SLAVE amp, this means only the audiosignal of the MASTER amp will be amplified.
Then, all controllers on the SLAVE Amp are without function and will be controlled by the MASTER amp.
In MASTER-Mode (Low Pass mode) you are able to limit the frequencies to above with the LP controller. All controllers are acti-
ve. When you use only one amplifier, the MODE switch must be in position MASTER.
The LP controller adjusts the cut-off point of the frequency range to above. The cut-off frequency is continuously adjustable from
8
35 Hz to 250 Hz.
The BASS LEVEL CONTROLLER port is for the cable of the enclosed bass remote controller and only to use in the MASTER
9
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.
POWER/PROTECT
10
If the POWER LED lights up, the amplifier is ready for operation.
If the PROTECT LED lights up, a malfunction is indicated. Refer in this case to the chapter TROUBLE SHOOTING.
The SLAVE IN/OUT RCA jacks are suitable to connect an additional amplifier in MASTER/SLAVE mode.

Refer to the chapter Interconnection Example: MASTER/SLAVE on page 23..
NOTE
Installation of RCA/Audio signal cables and power supply cables.
Ensure while installation not to lead the audio cables between the head unit and the amplifier together with the power supply wires
on the same side of the vehicle. The best is a real separated installation on the left and right cable channel of the vehicle to avoid
interferences on the audio signal. This stands also for the enclosed bass-remote wire, which should not be installed together with the
power supply wires.
