Dear MAGNAT Customer,

The POWER CORE FOUR 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 POWER CORE FOUR 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.

2. FEATURES

· Complementary push-pull final stage

· Automatic switching on/off via car radio

· Channel 1 and 2:

· High-pass and low-pass filters (band-pass) with continuously adjustable crossover frequency

· Infinitely variable bass equalisation

· Channel 3 and 4:

· Infinitely adjustable high pass filters

· DUPE circuit for duplicating the output signal of the channel 1 and 2 filters (bandpass and bass boost) at channel 3 and 4.

· Adjustable input sensitivity

· Bridgeable 4-/2-channel mode

· Tri-mode

· Electronic protective circuit against short circuiting, DC offset and excess temperature

· Mute switch for suppressing switch-on crackle interference

· Low-level outputs (cinch jacks) for connecting a subwoofer amplifier

· Status indicator (green LED) and overload indicator (red LED)

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 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.

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 25 mm² must be used to connect

the battery to the amplifier’s terminals.
