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 at the place of installation. The cooler’s ribs mustn’t contact any metal plating or any surfaces which could impair air circulation. The amplifier may not be installed in small confined spaces or spaces without air circulation (e.g. spare wheel recess or under the vehicle carpeting). Installation in the boot is recommended.
• Install the amplifier in such a way that it is protected as far as possible against vibrations dust and dirt.
• Make sure that the input/output cables are sufficiently distant from the power supply cables as 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 an expert to install the system, particularly if you want to install several loudspeakers or a complex multi-way system.

CONNECTIONS

POWER SUPPLY AND AUTOMATIC SWITCHING ON

Important notice:
Before commencing the installation, disconnect the plus terminals from the 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’s demands. Make sure that the power lines to GND and to the +12 V terminal have been sufficiently specified. A cable cross-section of at least 16 mm² (MPExclusive 1.0 XL)/6 mm² (MPExclusive 1.0) must be used to connect the battery to the amplifier’s terminals. First connect the amplifier’s GND terminal to the battery’s minus pole. The connection must be good. Dirt residues must be carefully removed from the battery’s connection point. A loose connection may cause malfunctions or interference noise or distortion.

The +12 V amplifier connection must then be connected with a power cable possessing an integrated fuse to the battery’s plus pole. The fuse must be located close to the battery, the length of cable from the battery’s positive pole to the fuse must be less than 60 centimetres 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.

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. This cable should not be laid on the side of the power supply leads but together with the audio cable.

LOUDSPEAKER CONNECTIONS

• The lowest terminal resistance is 2 ohm
• 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

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 control (2) 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.

LOW-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY
Set the desired cross-over frequency with the control (4). 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.

SUBSONIC FILTER
The subsonic function reduces the lowest bass frequencies. The reduction rate may be infinitely adjusted with the regulator (5). This allows distortions produced by excessive loudspeaker membrane movements to be effectively minimized without reducing the utilizable bass levels.

BASS-BOOST
The bass-boost function (3) is used to increase or equalize the lower bass frequencies.

VOLUME REMOTE CONTROL
The volume may be adjusted by using the supplied remote control. Please observe during installation that the remote control line shouldn’t be routed along the same side of the vehicle as the power supply cables. The remote control unit should be mounted on the dashboard or at any other easily accessible position. Now, the subwoofer volume may be adjusted independently from the settings on the radio.

OUTPUTS FOR CONNECTING ADDITIONAL AMPLIFIERS
The input signal of the INPUT connections INPUT L and R (1) is forwarded directly to the OUTPUT (6) L and R jacks. The OUTPUT connections allow the use of additional amplifiers without requiring additional T-plugs and cables.
