WHERE TO PUT MODULAR EXTENSIONS OBJECTIVES OF VRx PROJECT VRx6.420 VRx project was conceived in order to solve the problems which derive from the installation of a high quality car audio system. The long and constant work made with professional installers and the use of the most advanced, currently available technology allowed audison’s designers to attain totally new results in terms of power, reliability and exceptional versatility above all.
VRx6.420 GENERAL FEATURES Front/Rear configurations Conformity with “E” norms VRx models have a RF filter which makes them suitable to the new norms about radio-frequency disturbances emission inside cars before any others. A “common mode”, adequately dimensioned filter choke was inserted next to power supply input in order to prevent sudden voltage drops which commonly occur in similar circuit typologies.

Fans group insertion inside Terminals and Raccords INSTRUCTIONS Put the Terminal or the Raccord onto a flat surface. (As far as Terminals are concerned, the side with grilles must be facing upwards). Remove the front plate fixed through four screws by using multispanner supplied with the devices (pict. 1 and 2). Place the fans groups onto the flat surface and push them in order to insert them inside the extension body you are using, so that the fans group support guides snap into the slots (pict. 3). VRx4.

WARNING! • Do not remove the cover in order to reduce the risk of serious technical inconveniences. • Please apply to qualified staff for every necessary intervention inside the amplifier.
CABLES SIZE Power supply cables Power supply cables size is very important since quality of the amplifier performances, reliability and, above all, installation safety depend on it. As this matter is complex, varied and important, we recommend you to address audison’s specialised centres, where highly qualified professionals will be able to carry out these operations in the best way, realising a state-of-the-art installation.
EXTERNAL FUSE SIZE AND LOCATION VRx1.500 connections External fuse size must be calculated according to the type of system you want to realise and to its being made of a single amplifier or multiamplified.
WHERE TO PUT MODULAR EXTENSIONS VRX1C VRx1 controls. They must not be removed. INTERNAL FUSE REPLACEMENT VRx1.500 MULTICHANNEL EXTENSIONS WARNING! Controls under wooden strip HL12 - LM24 HL24 - BSA1 DMRX socket for a future extension. Do not put any modules into it. Before installing a new fuse, please remember to charge the external capacitor (if it is installed) through the special charge-discharge device supplied with Audison Cable Superfarad models.

VRx1.500 Controls and functions Leds Controls under wooden strip ON - Green led It indicates the amplifier is on. SAFETY - Red led It indicates protection intervention: excessively high temperature or output anomalies (direct current, short circuit or dangerously low load impedance). Protection intervention stops the amplifier functioning. Switch the amplifier off; when anomaly is eliminated, switch the amplifier on again.
