INTRODUCTION

Audison thanks you for preferring this product and compliments you on your choice since it was designed in order to insure outstanding musical and instrumental performances.

Before use instructions, please carefully read the safety norms you have to respect in order to avoid unpleasant inconveniences and to enjoy this product at best.

PRECAUTIONS

-Avoid to install the amplifier where temperature is below 0°C or above 55°C and in non ventilated places.

-The amplifier needs 12VDC power supply voltage with negative to ground. Be sure that your car electric system is compatible with the amplifier ordinary functioning.

-For safer driving, we recommend to adjust volume not to drown external traffic sounds.

WARNING!:

While installing the amplifier, make sure that the cable coming from the battery positive pole (+) doesn’t touch the amplifier heat sink.

The heat sink is directly connected to the battery negative pole (-) through the screws which fix it to the vehicle chassis. Its contact with the positive pole cable would cause short circuit and, thus, possible fires and battery damages.

Please connect power supply cables to the amplifier terminal blocks (POWER + and -) before and to battery AFTER, to get maximum safety.

CAUTIONS

INPUTS: If the source output signal ground (PRE OUT) is not connected to the source chassis and the system sound is not powerful enough or is distorted, try to solve the problem by connecting the output signal cable braided shield (PRE OUT) to a point of the source chassis.

OUTPUTS: Don’t connect –L and –R power outputs to each other or to ground (car chassis). In case you use an external crossover, make sure that channels grounds are not connected one to the other.
