4.2 AUDIO CABLES
When installing the audio cable between the cinch output of your car receiver and the cinch input of the amplifier inside your car, the
audio and power supply cables should, wherever possible, not be routed along the same side of the vehicle. We recommend an isolated
installation, e.g. routing the power cable through the cable duct on the left-hand side and the audio cable through the cable duct on the
right-hand side or vice versa. This reduces interference due to crosstalk into the audio cables.
4.3 LOUDSPEAKER CONNECTIONS
·
In normal operating mode (i.e. one loudspeaker on each individual amplifier channel), the lowest terminal resistance is 2 ohm per
channel.
·
In bridging mode (two amplifier outputs combined) the lowest terminal resistance doubles to 4 ohm.
·
The impedance in tri-mode may not fall below 2 ohm per channel.
·
Never connect the loudspeakers' minus terminals to the vehicle chassis.
·
Never connect the +12 V supply voltage to a loudspeaker output as this would destroy the amplifier final stage.
If the amplifier is operated with lower terminal resistances or incorrectly used as described above, both the amplifier and the
loudspeakers may be damaged. The warranty becomes void in such cases.

OPERATING ELEMENTS AND IN/OUTPUTS
5.1 SETTING THE INPUT SENSITIVITY
The input sensitivity may be adapted to any car radio or tape deck. Turn the volume control of your radio to its central position and then
adjust the input-level controls (6) and (10 to produce an average medium volume. This setting usually provides sufficient power reserves
at optimum weighted noise voltage.
ATTENTION: only reproduce loud test noises briefly to prevent damaging the loudspeakers.
5.2 LOW-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY
If the amplifier is used as a subwoofer amplifier, set the switch (2)/(14) to "LP". Set the desired cross-over frequency using the control (3)/
(12). This makes the filter adaptable to the installed woofer's sound requirements.
The filter's high edge steepness is responsible for the precision reduction of medium and high frequency ranges.
5.3 HIGH-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY
If the amplifier is to be used as an amplifier for satellite loudspeakers (mid-range/tweeter loudspeakers), set switch (2)/(14) to "HP". Set the
desired cross-over frequency using the control (4)/(11). Only the frequencies above the set cross-over frequency will then be amplified. This
effectively minimizes distortions caused by excessive membrane movement at low frequencies and small satellite loudspeakers without
reducing the bass level.
5.4 BASS-BOOST
The bass-boost function (1)/(13) is used to increase or equalize the lower bass frequencies.
5.5 OUTPUTS FOR CONNECTING ADDITIONAL AMPLIFIERS
The input signal of the LINE INPUT connections CH1 and CH2 (8) is forwarded directly to the OUTPUT (7) L and R jacks. The OUTPUT
connections allow the use of additional amplifiers without requiring additional T-plugs and cables.

POWER SUPPLY / REMOTE SWITCH-ON CONNECTIONS
(1) GND terminal for the ground, to the battery's minus pole
(2) REM terminal for remote switch-on
(3) Terminal for + 12 V battery voltage
(4) Battery
(5) Cable fuse
(6) To your car radio's automatic aerial connection
If your car is not equipped with an automatic aerial connection, connect this cable's plus pole (+) to the ignition lock. An on/off switch
should be inserted in this case. Make sure that this switch is switched off if the amplifier is not used.
FIG. 2
4-CHANNEL MODE
Connect and set the amplifier as shown in Fig. 2 if it is to be controlled by a car radio with four output channels and used with four
loudspeakers:
(1) To the car radio, front left output
(2) To the car radio, front right output
(3) To the car radio, rear left output
(4) To the car radio, rear right output
(5) Front left loudspeaker
(6) Front right loudspeaker
(7) Rear left loudspeaker
(8) Rear right loudspeaker
FIG. 3/4 3-CHANNEL MODE
The 3-channel mode uses the high-pass filter for channels 1/2 and the low-pass filter for Channels 3/4. Section 5 describes how they are
used.
