FUNCTIONS AND OPERATIONAL CONTROLS
1
The SLAVE IN/MASTER OUT 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 OUT.

The INPUT 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 to 0.2 Volts.
6
The SUB SONIC controller (Subsonicfilter) limits the ultralow and not hearable frequencies of the audiosignal to below, to avoid
a mechanical and electical overloading on the subwoofer. The cut-off frequency is adjustable from 15 to 55 Hz and depends on
the size of the subwoofer.
Connect the REMOTE port with the bass remote controller (only in the MASTER mode). The bass remote controller adjust the
bass level e.g. out of the driver’s seat. Please use only the enclosed bass remote controller and cable.

The BASS BOOST controller adjusts the bass enhancement between 0db and +12dB.

continuously adjustable from 40 Hz to 180 Hz.

The MASTER OUT / SLAVE IN RCA jacks are suitable to connect an additional amplifier in MASTER/SLAVE mode.
Attend therefor the chapter Interconnection Example: MASTER/SLAVE on page 19.

The LINE INPUT RCA jacks must be connected with the RCA output jacks of the headunit. Both of them must be used. If your
headunit provides only one RCA jack, use a y-connector.
