CLK2 - LRx Cooling Kit
This cooling system is specially designed to provide LRx amplifiers with the right working temperature.
CLK2 should be used when LRx amplifiers work in extremely hard conditions (very low loads) or in installations where space is too narrow and heat sink cooling is not enough. It consists of two units to apply onto the amplifier sides; each of them is provided with an electronically controlled fan. Its intervention depends on a thermal sensor that starts the system as soon as LRx heat sink reaches 45°C. The same sensor is connected to a special circuit which controls the two fans speed progressive increase when temperature increases, too.
Air flux constant control allows the amplifier very good thermal stabilization and limits noise.

VCA-VCA1D MODULES INSERTION
LRx 5.600 can accept one of the three optional kits which allow the subwoofer volume remote control: VCR01K, VCRAK or VCRDK.
These kits have a specific module, VCA or VCA1D, to insert into the amplifier through the setting panel.
Installation:
1 - Remove BYP12 bridge.
2 - Insert VCA/VCA1D module.
- Insertion key. It prevents the module from being inserted in the wrong way.
