Dear MAC AUDIO Customer,
The MICRO XL 4000 car hi-fi power amplifier will enable you to satisfy your high demands on sound reproduction in your car. With its
impressive deep-bass power reserves, low harmonic content and neutral reproduction, the MICRO XL 4000 takes car hi-fi to new heights.
The amplifier is characterized by low operating current, rapid switching capabilities and excellent temperature stability. Increased output
power can be achieved by switching two amplifier channels in an amplifier together in bridging mode. Experience and enjoy how this high-
tech machine perfectly reproduces magnificent sound.
Please read all of the owner's manual before installing and using the amplifier.

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. It is very
important that the cooler's cooler ribs do not 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 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.

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 20 mm² must be used to connect
the battery to the amplifier's terminals.
