FUNCTIONS AND OPERATIONAL CONTROLS
1
The
LINE INPUT RCA jacks
must be connected with the RCA output jacks of the headunit.
By connecting only the CH1/2 jacks, the
INPUT MODE
switch must be set to the
2CH
position.
2
POWER/PROTECT (also featured on the bass remote controller)
If the POWER LED lights up, the amplifier is ready for operation.
If the PROTECT LED lights up, a malfunction is indicated. Attend in this case the chapter
TROUBLE SHOOTING
.

The
BASS BOOST CH1/2 and CH3/4 controllers
adjust the bass boost enhancement continuously from 0dB to +18dB at
45 Hz for the regarding channel pair (Channel 1/2 or Channel 3/4).
5
The
CH1/2 and CH3/4 X-OVER switch
selects the required operation mode of the amplifier on the regarding channel pair
(Channel 1/2 or Channel 3/4).
Position LP/BP:
Lowpass mode (the higher frequencies will be eliminated. Adjustable by the lowpass controller.)
The HI PASS 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 lowpass controller, no sound is hearable.
Position HP:
Highpass mode (the higher frequencies will be eliminate. Adjustable by the highpass controller.)
Position FULL:
Fullrange mode (the whole frequencies will be amplified). The controllers LOW PASS, HIGH PASS and
BASS BOOST are without function.
6
The
LOW PASS CH1/2 and CH3/4 controllers
adjust the cut-off point of the frequency range to above for the regarding channel
pair (Channel 1/2 or Channel 3/4). The cut-off frequency is continuously adjustable from 40 Hz to 4000 Hz (4 kHz).
7
The
INPUT MODE switch
must be in
2CH
position, if you connect only one RCA stereo audio cable with the CH1/2 line inputs.
Select the position
4CH
, if you connect two RCA stereo audio cables with CH1/2 and CH3/4 line inputs.
The fader function of your headunit works only in the
4CH
mode.
If you have select the
2CH
mode, the input signal of LINE INPUT CH1/2 will be routed to the channelpair CH3/4. Due to this, only
one RCA stereo audio cable is required and no Y-Adaptors are required.
8
The
REMOTE port
is for cable of the enclosed bass remote controller and only to use in the LP/BP mode. With this bass remote
controller, you are able to adjust the bass level e.g. from the driver’s seat. Please use only the enclosed bass remote controller
and cable.
9
The
HIGH PASS CH1/2 and CH3/4 controllers
adjust the cut-off point of the frequency range to below for the regarding channel
pair (Channel 1/2 or Channel 3/4). The cut-off frequency is continuously adjustable from 10 Hz to 4000 Hz (4 kHz).
10
The
LEVEL CH1/2 and CH3/4 controllers
adjust the input sensitivity of the amplifier to align the audio signal of the head unit
for the regarding channel pair (Channel 1/2 or Channel 3/4). The input sensitivity is adjustable from 9 to 0.2 Volts.
11
12
The
LINE OUT RCA jacks
provide a linear summed fullrange audiosignal to supply an additional amplifier.

The optional BALANCED INPUT is unlike the regular RCA-cables insusceptible against interspersion and interferences of the
vehicle’s electronics. You need therefor a Balanced-Line-Transmitter with a special cable, which can be connected between the
head unit and the amplifier. The Balance-Line-Transmitter is not included in delivery.
Attend therefor the further information
on page 31.
Never use the Balanced-Input and the RCA-Inputs at the same time.
The
STEREO 12 dB / MONO 24 dB
push button advanced the slewrate of the lowpassfilter of CH3/4 to 24db/octave.
Switch only on 24dB, when you run the amplifier in bridged mode on CH3/4 with a subwoofer.
