1
The X-OVER MODE switch selects the required operation mode:
Position LPF/BPF: Lowpass mode (the higher frequencies will be eliminated. Adjustable by the LPF controller.)
The HPF controller works in this operation mode as subsonicfilter and eliminates the lower frequencies (Bandpass-Mode).
NOTE: If this controller is turned to a higher value than the LPF controller, no sound is hearable.
Position HPF: Highpass mode (the higher frequencies will be eliminated. Adjustable by the HPF controller.)
Position FULL: Fullrange mode (the whole frequencies will be amplified).

The BASS LEVEL CONTROLLER port is for the cable of the enclosed bass remote controller. 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 controller works only in LPF/BPF.
The remote controller works as level attenuator and if the knob is on MAX position, the actual level which is set by the LEVEL
controller on the amplifier will be played back. By turning the knob counter-clockwise the level will be attenuated and lower.

The HPF controller (HIGHPASS) adjusts the cut-off point of the frequency range to below for each channelpair.
The cut-off frequency is continuously adjustable from 10 Hz to 100 Hz.
The INPUT LEVEL MODE push button sets the operation mode of the LINE IN RCA connectors. In pushed position (LOW), the
LINE IN is suited for pre-amplifier signal (low level signals, pre-amplifier outputs from the head unit). In the non-pushed position
(HI) the LINE IN connectors are suited for high level signals from the speaker outputs of the headunit. Please check the instructions
on page 16.

The BOOST controller defines the bass boost from 0 to 12dB @ 50Hz.
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).

Der LEVEL-Regler bestimmt die Eingangsempfindlichkeit (Anpassung an das Ausgangssignal des Steuergeräts).
Der Regelbereich liegt zwischen 6 Volt (MIN) und 0.2 Volt (MAX).

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.

The LINE IN RCA jacks must be connected with the RCA output jacks of the headunit.

The LINE OUT RCA jacks provide a linear fullrange audiosignal to supply an additional amplifier.

The PHASE-Controller allows to set the phase between 0° and 180° to match the run time of the output signal with the vehicle’s
interior acoustic.
