The interference from a TV can wreak havoc with your IR control system. Xantech designed this Universal Hidden Link IR Receiver to resist the interference from plasma, LCD and LED TVs, as well as fluorescent and compact fluorescent lighting (CFL), and sunlight – so you can mount this receiver in any room with confidence. The Hidden Link IR Receiver is a small shelf-top infrared repeater assembly. The package includes an IR receiver, connecting block. power supply and four emitters. The Hidden Link IR Receiver is equipped with a 7-foot cable and a 3.5mm stereo mini plug, which is plugged directly into the “IR RCVR” jack on the connecting block.
