Shure SLXD4 Digital Wireless Receiver (J52: 558 to 602 + 614 to 616 MHz)

The Shure SLXD4=-J52 is a digital wireless receiver designed for single-channel operation in the J52 UHF band, covering 558 to 602 and 614 to 616 MHz. It pairs with any SLX-D Series transmitter and passes 24-bit audio with a wide 120 dB dynamic range. Musicians, presenters, and worship leaders will notice the 3.2 ms latency that keeps in-ear monitors and stage wedges in tight sync with live performance.

Inside a steel half-rack chassis, the unit uses predictive antenna switching to hold a clean signal, and the two BNC antennas can be removed for remote placement when needed. An LCD screen with backlighting shows RF strength, battery life, and audio meters, so you can make quick adjustments even in low-light racks. Balanced XLR and 1/4 inch outputs feed mixers, recorders, or powered speakers without additional adapters.

For multi-mic setups, an Ethernet port links several receivers, enabling coordinated scans and frequency assignment. With 1,840 selectable frequencies and support for up to 32 compatible systems per band, production teams can build reliable wireless rigs in conference centers, theaters, houses of worship, and small to mid-sized music venues. Included rackmount hardware and a 15 V DC power supply let you move from the box to a working install in minutes, yet the compact size also suits portable fly racks and road cases.
