FUNCTIONS AND OPERATIONAL CONTROLS
1 2
POWER/PROTECT (Also located on the supplied Bass Level Controller)
1
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 BASS LEVEL CONTROLLER port is for the cable of the enclosed bass remote controller. With this bass remote controller,
2
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 mode.
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 X-OVER MODE switch selects the required operation mode:
3
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 LEVEL controller adjusts the input sensitivity of the amplifier to align the audio signal from the head unit.
4
The input sensitivity is adjustable from 6 Volts (MIN) to 0.2 Volts (MAX).
The BOOST controller defines the bass boost from 0 to 12dB @ 50Hz.
5
The LPF controller (LOW PASS)adjusts the cut-off point of the frequency range to above.
6
The cut-off frequency is continuously adjustable from 30 Hz to 150 Hz.
The HPF controller (HIGHPASS) adjusts the cut-off point of the frequency range to below for each channelpair.
7
The cut-off frequency is continuously adjustable from 10 Hz to 1200 Hz (1.2 kHz).
The LINE IN RCA jacks must be connected with the RCA output jacks of the headunit.
8
9
The LINE OUT RCA jacks provide a linear fullrange audiosignal to supply an additional amplifier.
