for safety reasons. Only insert the fuse when all installation work, including the connection of the loudspeakers, has been completed.

Now connect the car hi-fi receiver’s remote control connection to the amplifier’s REM control jack. A cable with a cross-section of 0.75 mm²

is sufficient for connecting the amplifier’s REMOTE connection and the control device.

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.

This also applies to the connecting cable for the remote control for regulating the volume of the rear channels. This cable should not be

laid on the side of the power supply leads but together with the audio cable.

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.

5. OPERATING ELEMENTS

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 is central position and then

adjust the input-level control (11)/(12) 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 BAND-PASS FUNCTION

Set the switch (4)/(3) to “BP” if you want to use Channels CH1/2 or CH3/4 respectively for the subwoofer amplifier. Controls (10)/(9) and (6)/

(5) may now be used to set the lower and upper limit frequencies of the resulting band-pass. This function can be used to drive a subwoofer

(high-pass regulator (10)/(9) at 10 Hz) or to realise a bass kick response (high-pass regulator (10)/(9) at approx. 80 to 100 Hz). Adjust the

low-pass regulator to the desired crossover frequency.

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 (4)/(3) to „HP“. Set the

desired cross-over frequency with the control (10)/(9). 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 elevates or distorts the lower bass ranges. Infinitely variable accentuation level using control (2)/(1).

5.5 OUTPUTS FOR CONNECTING ADDITIONAL AMPLIFIERS

The input signal of the LEVEL INPUT connections CH1, CH2, CH3, CH4 (13 and 14, Fig. 6) is accumulated and forwarded directly to the

OUTPUT (15) jacks. The LINE OUTPUT connections allow the use of a subwoofer amplifier without requiring additional T-plugs and cables.

5.6 REMOTE CONTROL FOR REGULATING THE VOLUME OF THE REAR CHANNELS

The volume of the rear channels (the outputs designated CH3 and CH4) can also be regulated using the remote control supplied. When

fitting this device, it must be ensured that the remote control cable is not laid on the same side of the vehicle as the power supply for

the amplifier (see Chapter 4.2). The remote control should be installed on the dashboard or other easily accessible location. If the rear

channels are used to operate a subwoofer, the volume of the subwoofer can be adjusted independently of the settings on the car radio.

Use is recommended in the layout shown in fig. 3.

FIG. 1 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.
