3. IMPORTANT INSTALLATION INFORMATION

• This appliance may only be connected to a 12 volt system with negative ground.
• The heat radiated when the amplifier is used means that sufficient air circulation is required place of installation. It is very important that the cooler's cooler ribs do not contact any or any surfaces which could impair air circulation. The amplifier may not be installed in s confined spaces or spaces without air circulation (e.g. spare wheel recess or under the va carpeting). Installation in the boot is recommended.
• Install the amplifier in such a way that it is protected as far as possible against vibrations and dirt.
• Make sure that the input/output cables are sufficiently distant from the power supply cables a. otherwise interference may occur.
• Make sure that the fuse and operating elements are accessible after installation.
• The appliance's reliability and performance depend on the quality of installation. Preferably get expert to install the system, particularly if you want to install several loudspeakers or a c multi-way system.

4. CONNECTIONS

4.1 POWER SUPPLY AND AUTOMATIC SWITCHING ON

Important notice: Before commencing the installation, disconnect the plus terminals from car battery in order to prevent short circuits.

The power cabling usually installed in on-board car networks is not sufficient for a power amplifier demands. Make sure that the power lines to GND and to the +12V terminal have been sufficiently specified. A cable cross-section of at least 10mm^2 must be used to connect the battery to the terminals.

First connect the amplifier's GND terminal to the battery's minus pole. It is very important that connection is good. Dirt residues must be carefully removed from the battery's connection point. connection may cause malfunctions or interference noise or distortion.

The +12V amplifier connection must then be connected with a power cable possessing an internal fuse to the battery's plus pole. The fuse must be located close to the battery, the length of the battery's positive pole to the fuse must be less than 60 centimetres for safety reasons. Only if the fuse when all installation work, including the connection of the loudspeakers, has been completely

Now connect the car hi-fi receiver's remote control connection to the amplifier's REM control pad with a cross-section of 0.75mm^2 is sufficient for connecting the amplifier's REMOTE connection to control device.

4.2 AUDIO CABLES

When installing the audio cable between the cinch output of your car receiver and the cinch in amplifier inside your car, the audio and power supply cables should, wherever possible, not be along the same side of the vehicle. We recommend an isolated installation, e.g. routing the port through the cable duct on the left-hand side and the audio cable through the cable duct on the 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 lower terminal resistance is 2 ohm per channel.
  In bridging mode (two amplifier outputs combined) the lowest terminal resistance doubles to 4
  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 final stage.

If the amplifier is operated with lower terminal resistances or incorrectly used as described both the amplifier and the loudspeakers may be damaged. The warranty becomes void in cases.

5. 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 to its central position and then adjust the input-level control (5) to produce an average medium. 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 (1) to "LPF". Set the desired frequency with the control (3). This makes the filter adaptable to the installed woofer's sound in. The filter's high edge steepness is responsible for the precision reduction of medium and high 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 loudsp) set switch (1) to "HPF". Set the desired cross-over frequency with the control (2). Only the fre above the set cross-over frequency will then be amplified. This effectively minimizes distortions by excessive membrane movement at low frequencies and small satellite loudspeakers without re 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 (7) is forwarded directly to the LINI and R jacks. The LINE OUT connections allow the use of additional amplifiers without requiring T-plugs and cables.

If your car is not equipped with an automatic aerial connection, connect this cable's plus 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 use two loudspeakers. The high-pass filter must also be activated if the amplifier is also used for loudspeakers. See Chapter 5.3.
