Wireless, High-Fidelity Audio Transmitter & Receiver Kit Using state-of-the-art wireless technology, the JLINK™ TRX system delivers pure, high-fidelity sound throughout your home, invisibly and effortlessly. By broadcasting at an ultra-high frequency of 2.4 GHz, the JLINK™ TRX lets you connect any two line-level audio devices together, without the use of RCA signal cables to connect in between. Now you can send crystal clear, stereo sound from a source unit to a receiver, preamp or powered loudspeakers, wirelessly, up to 100 feet away (30 meters) without needing to route or hide long expanses of signal cables. RCA-type input/output connectors are compatible with most audio equipment and a compact design makes it easy to hide the transmitter and receiver chassis out of sight. A JLINK™ port is also included on the receiver for direct connection with JLINK™ compatible JL Audio products.
