LRx 4.300

ACCESSORIES

VCR01K,VCRAK and VCRDK

LRx 4.300 can accept one of the optional kits that allow the subwoofer volume remote control. VCR01K and VCRAK are analogue and special for sub; VCRDK is digital and can be used for master volume control or for level control of any ways in a multichannel system.

These kits are available as accessories and consist of three elements:

1)Volume adjuster (VCR01/VCRA/VCRD);

2)VCA/VCA1D module to put inside the amplifiers;

3)Wire to connect VCR01/VCRA/VCRD adjusters to the proper sockets in the amplifier rear panel and to the car lights switch, in order to light it up.

Install VCR01/VCRA/VCRD adjusters in a place you can easily and comfortably reach, according to the following connection diagram.
