The Shure QLXD4 is a digital half-rack wireless receiver housed in a rugged, full-metal chassis and compatible with QLXD1 bodypack and QLXD2 handheld transmitters. It provides instructors, presenters, and broadcasters with professional-quality audio, reliable RF performance, and secure AES 256-bit encryption. Easy to set up and operate, it is ideal for use in TV broadcast or sound-reinforcement applications in medium-sized venues and houses of worship, as well as A/V installations in conference, educational, and corporate facilities.

The QLXD4 operates in the G50: 470 to 534 MHz UHF band with a 64 MHz tuning range and 2560 selectable frequencies. It delivers pristine 24-bit/48 kHz digital audio with clarity, accurate low end, and crisp transient response. The receiver utilizes Digital Predictive Switching Diversity to protect the transmission from interference and provide solid RF signal stability without audio artifacts. You can run up to 60 mic channels at the same location.

The unit features audio and RF meters, 60 dB of gain control, and both mic/line XLR and 1/4" instrument outputs. A large LCD screen and intuitive controls let you quickly make adjustments, even in low-light situations. Additional features include automatic frequency scanning, IR sync, and internal limiting to prevent clipping.

The Ethernet port allows multiple receivers to be easily networked together for simplified frequency coordination and deployment via Shure's Wireless Workbench (WWB) software.
