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 (7) to “HPF”. Set the desired cross-over frequency with the control
(5). 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 (4) 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 L and R (2) is forwarded directly to the LINE
OUT (1) L and R jacks. The LINE OUT connections allow the use of additional amplifiers
without requiring additional T-plugs and cables.
FIG. 1 POWER SUPPLY / REMOTE SWITCH-ON CONNECTION
(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 STEREO MODE
Connect and set the amplifier as shown in Fig. 2 if it is to be controlled with two output channels
and to use two loudspeakers. The high-pass filter must also be activated if the amplifier is also
used for satellite loudspeakers. See Chapter 5.3.

(2) To the car radio, right output
(3) Loudspeaker left
(4) Loudspeaker right
FIG. 3 BRIDGE MODE WITH STEREO CAR RADIO
If the amplifier has to generate more power to operate a subwoofer, connect and set it as
shown in Fig. 3. The use of the low-pass filter is described in Chapter 5.2.
