Audio Cables; Loudspeaker Connections - MAC Audio MP MONO Owner's Manual/Warranty Document

· Install the amplifier in such a way that it is protected as far as possible against vibrations and 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.
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 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.
