Shure ULXD4Q-G57

The Shure ULXD4Q is a professional-grade quad-channel digital wireless receiver designed for high-demand environments such as large venues, houses of worship, and corporate AV installations. With four independent receivers in a single 1RU chassis, it delivers powerful wireless performance while conserving rack space. Operating in the G57 UHF band (470 to 608 MHz) with an expansive 138 MHz tuning range, it supports up to 60 channels per band in Standard or High-Density modes.

The ULXD4Q integrates Dante digital audio networking, audio summing, and RF cascade ports, making it an ideal solution for networked audio systems. Built-in features like Digital Predictive Switching Diversity, AES-256 encryption, and automatic frequency coordination ensure reliable, interference-free operation. Each channel includes independent gain control, XLR outputs, and a clear backlit LCD for easy monitoring and adjustments.

Engineered for seamless system integration, the receiver supports control via Shure Wireless Workbench, SystemOn, and mobile apps, with compatibility for external control systems like AMX and Crestron. This makes the ULXD4Q a robust, scalable choice for complex installations requiring pristine digital sound and maximum channel density.
