1.1 Warnings

This manual should be read very carefully before installing the unit. The warranty will become void in case of negligence, incorrect handling, improper use or tampering of the circuit by non authorised personnel.The warranty will also be void in case of faults developing due to strong accidental power surges from the mains power supply. It is therefore necessary to install suitable protection on the power line, ensuring that the connection to the earth is as accurate as possible, in compliance with local legislations.

1.2 Description of the amplifier

The stereo amplifier, item F503, ensures accurate reproduction of the sound signal, both from the SCS/BUS and, in alternative, from the AUX input (MP3 reader, CD player, etc.). The wide range of adjustments of high and low tones available, the 10 preset equalisation levels, as well as the ad-ditional 10 levels that can be customised by the customer, the virtual surround, to name a few, ensure pleasurable listening in each room, following the taste of the user.
