· 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.
4. CONNECTIONS
4.1 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. It is very important that the connection is 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.
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. This cable should not be laid on the side of the
power supply leads but together with the audio cable.
4.3 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.
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 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.
5.2 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.
5.3 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.
5.4 BASS-BOOST
The bass-boost function (3) is used to increase or equalize the lower bass frequencies.
5.5 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 at the radio.
5.6 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.
