Shure ULXD4Q Quad-Channel Digital Wireless Receiver (H50: 534 to 598 MHz)

The Shure ULXD4Q=-H50 is a quad channel digital wireless receiver that brings four independent RF channels into one rugged 1U rack unit. Built for demanding tours, corporate AV teams, and fixed installations in houses of worship, it operates in the H50 band between 534 and 598 MHz and pairs seamlessly with Shure handheld or bodypack transmitters.

Each channel lives on its own front-panel display with individual gain control, RF and audio metering, and a balanced XLR output on the rear panel. This layout lets an engineer route each microphone to separate mixers, recorders, or loudspeaker zones without extra hardware. Internal limiting protects against sudden peaks, so speeches stay clear and musical passages remain distortion-free.

For networked sound systems, the built-in Dante ports carry all four channels as low-latency, 24-bit and 48 kHz audio straight to a digital console or software recorder over a single Ethernet cable. An additional network port supports monitoring and control through Wireless Workbench or third-party systems, making frequency coordination and remote gain adjustments quick, even from the back of a large auditorium.

When security matters, such as in government meetings or corporate boardrooms, AES-256 encryption keeps every transmission private. A 64 MHz tuning range and efficient RF performance allow up to 60 compatible channels in Standard mode, while RF cascade ports simplify antenna distribution so a pair of directional antennas can serve multiple racks.

Whether you are deploying a small speech setup or a full band’s worth of microphones, the ULXD4Q=-H50 delivers transparent sound, flexible networking, and solid RF reliability that stays consistent show after show.
