Shure ULXD4 Single-Channel Digital Wireless Receiver (G50: 470 to 534 MHz)

The Shure ULXD4=-G50 is a single-channel digital wireless receiver that works in the G50 UHF band, covering 470 to 534 MHz. Designed for stages, lecture halls, houses of worship, and broadcast control rooms, it gives engineers a straightforward way to build reliable wireless systems without compromising audio quality.

The receiver processes audio at 24-bit and 48 kHz, which means it captures every detail of a performance with a dynamic range that exceeds 120 dB. Digital Predictive Switching Diversity constantly evaluates both antenna signals and selects the cleanest path, so dropouts remain rare even in RF-dense environments.

The ULXD4=-G50 can handle up to 60 compatible channels in Standard mode and up to 90 channels when High-Density mode is engaged, making it a practical choice for multiroom conference centers or touring rigs that need many microphones running at once. If security matters, AES-256 encryption protects each transmission, an advantage for corporate events and government venues.

Day-to-day operation is straightforward. A steel chassis that mounts in a half-rack space keeps the unit safe on the road, front-panel meters show RF and audio levels at a glance, and up to 60 dB of gain adjustment is available right on the front knob. Balanced XLR and quarter-inch outputs connect easily to mixers or recording interfaces.

For larger systems, the built-in Ethernet port allows networked control, frequency coordination, and monitoring through Wireless Workbench software or the ShurePlus Channels mobile app. Remote access lets technicians walk the venue with a tablet and make adjustments without returning to the rack.

Whether you manage a rental inventory, run a permanent install, or mix live shows night after night, the ULXD4=-G50 delivers the consistency and control that keep wireless headaches to a minimum.
