Dear MAGNAT Customer,

The RX 44 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 RX 44

takes car hi-fi to new heights. The amplifier is characterized by low operating current, rapid switching capabilities

and excellent temperature stability. 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.

GB 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.

GB 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 controls (12) and (13) 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.
