Shure QLXD14 Wireless Guitar System (J50A: 572 to 608 + 614 to 616 MHz)

The Shure QLXD14-J50A is a digital wireless system created for guitarists and bassists who want freedom of movement without giving up the natural sound of their instrument. Operating in the J50A band from 572 to 608 MHz and 614 to 616 MHz, it delivers a stable connection in venues where crowded RF space can be a challenge.

The package pairs a rugged bodypack transmitter with a half-rack receiver. The transmitter locks to the included instrument cable so accidental unplugging is no longer a concern, and it runs for as long as nine hours on two AA batteries, enough to cover rehearsals, performances, and encores.

A 24-bit digital audio path keeps every nuance intact, while latency stays at a fast 2.9 ms so timing feels immediate. Players can step as far as 330 ft from the receiver without dropouts, a range that covers large stages, festival risers, or the entire span of a sanctuary.

Setup is straightforward. Automatic frequency scanning finds a clear channel in seconds, and Digital Predictive Switching Diversity continually watches for interference before it becomes audible. In spaces that host several bands or multiple wireless instruments, as many as 60 QLXD systems can operate simultaneously. When confidentiality matters, AES 256-bit encryption secures the signal end to end.

The receiver provides XLR and quarter-inch outputs for direct connection to amplifiers, pedalboards, or a mixing desk, and visible audio and RF meters make on-the-fly checks easy. Ethernet networking lets engineers link the system to Shure Wireless Workbench software for remote monitoring and coordinated frequency management across an entire venue.

Whether you are a touring guitarist needing a dependable travel rig, a worship leader who wants a neat stage without cables, or a theater technician juggling quick changeovers, the QLXD14-J50A offers a reliable solution that lets musicians concentrate on their performance instead of their gear.
