The LF Audio WRC is a wireless relay controller hub with 24 output pins, each capable of driving a fully independent relay or signal-sense channel for external relays, DSPs, amplifiers, radios, lightbars, camping gear, fridges, TVs, and other control-signal devices. A touch screen handles on-board programming and control, while AuralSync™ and Bluetooth connectivity link it to other LF-Audio gear such as the WDD and WVC, as well as the AuralSync™ app.

Program intelligent timers to power amplifiers seconds after the radio or DSP to avoid turn-on pop, build logic that shuts amps down when a WTH detects over-temperature conditions, switch fans based on WTH and WVC-PRO temperature probe values, or cut an external lightbar when an HPVM or HPVM-PRO senses low voltage. High-amperage loads require external relays matched to the use case.
