ACCESSORIES
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.
