Shure ULXD4 Single-Channel Digital Wireless Receiver (J50A: 572 to 608 + 614 to 616 MHz)

The Shure ULXD4=-J50A is a single-channel digital wireless receiver that gives sound engineers the confidence of pristine, 24-bit/48 kHz audio while operating in the J50A band from 572 to 608 MHz and 614 to 616 MHz. Designed for venues where the show has to run without surprises, it provides the fidelity artists expect and the control technicians need.

In spaces such as corporate conference halls, houses of worship, theaters, or outdoor stages, reliable radio performance matters as much as sonic quality. The ULXD4 tackles both challenges through Digital Predictive Switching Diversity, a technology that evaluates signal paths in advance and selects the cleanest one before interference can be heard. A wide 72 MHz tuning window and operating range up to 330 feet make frequency coordination straightforward, even in busy RF environments.

When privacy is essential, such as during confidential meetings or live broadcasts, the built-in AES-256 encryption keeps every word protected from eavesdropping. Pair the receiver with any compatible ULX-D handheld or bodypack transmitter and lock in settings instantly with the front-panel sync function.

Integration into modern audio systems is simple. Balanced XLR along with unbalanced 1/4-inch outputs connect directly to mixers, recorders, or monitor rigs. An Ethernet port lets you place the ULXD4 on the same network as other Shure devices, opening access to the free ShurePlus Channels app for iOS. From a tablet or phone you can monitor RF strength, audio levels, and battery status without leaving the mix position.

Whether you are installing a permanent system in a sanctuary, building a rental inventory for corporate AV, or running a touring rig that changes cities nightly, the ULXD4=-J50A delivers consistent performance you can count on.
