Dear MAGNAT Customer,

The EDITION FOUR / EDITION FOUR LIMITED 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 EDITION FOUR / EDITION FOUR LIMITED 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.

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 10 mm^2 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 should be located close to the battery; for safety reasons, the cable from the positive terminal of the battery to the fuse must not exceed 60 cm in length. 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 0.75mm^2 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.

4.3 LOUDSPEAKER CONNECTIONS

In normal operating mode (i.e. one loudspeaker on each individual amplifier channel), the lowest terminal resistance is 2 ohm per channel.

- In bridging mode (two amplifier outputs combined) the lowest terminal resistance doubles to 4 ohm.

· The impedance in tri-mode may not fall below 2 ohm per channel.

- 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 is central position and then adjust the input-level control (3) 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 switch (5) to "LPF" if you want to use Channels CH1/2 or CH3/4 respectively for the subwoofer amplifier. Set the desired crossover 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 precise reduction of middle and high frequency ranges.

5.3 HIGH-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY

If the amplifier is to be used as an amplifier for satellite loudspeakers (mid-range/tweeter loudspeakers), set switch (5) to "HPF". Set the desired cross-over frequency with the control (4). Only the frequencies above the set cross-over frequency will then be amplified. This effectively minimizes distortions caused by excessive membrane movement at low frequencies and small satellite loudspeakers without reducing the bass level.

5.4 BASS-BOOST

The bass-boost function elevates or distorts the lower bass ranges. Infinitely variable accentuation level using control (6).

5.5 OUTPUTS FOR CONNECTING ADDITIONAL AMPLIFIERS

The input signal of the INPUT connections CH3 / CH4 is forwarded directly to the OUTPUT jacks. The OUTPUT connections allow the use of additional amplifiers without requiring additional T-plugs and cables.
