Shure ULXD4Q G57 Description
The Shure ULXD4Q G57 is part of the ULX-D digital wireless system, offering four independent receiver channels in a rugged, space-efficient rackmount design. Its wide 470 to 608 MHz tuning range provides flexibility for complex wireless installations, while Digital Predictive Switching Diversity and automatic frequency scanning help maintain dependable RF performance. The system supports compatible ULX-D handheld, bodypack, boundary, and gooseneck transmitters, making it suitable for conferences, presentations, theatrical productions, and live sound reinforcement.
Designed for demanding audio applications, the receiver delivers 24-bit/48 kHz digital audio with more than 120 dB of dynamic range and latency below 2.9 milliseconds. Each channel includes independent gain control, RF and audio metering, and a balanced XLR output with selectable microphone or line level. Shure's Gain Ranging technology optimizes system dynamic range, while internal limiting helps prevent digital clipping. AES-256 encryption adds security for applications where wireless audio privacy is essential.
For networked production environments, dual Ethernet ports provide Dante digital audio connectivity and advanced control integration. Multiple ULX-D receivers can be coordinated through Shure Wireless Workbench software, allowing technicians to manage frequencies, monitor RF conditions, and respond to interference alerts. Two RF cascade ports simplify antenna signal distribution to another compatible receiver, while audio summing enables multiple receiver channels to be routed through selected outputs. High-Density mode also allows greater channel density in compatible short-range wireless deployments.
Constructed with a rugged steel and aluminum chassis, the ULXD4Q G57 is built for dependable operation in touring racks, installed sound systems, and professional A/V environments. Its intuitive backlit LCD, front-panel controls, channel-specific LED meters, and internal AC power supply simplify setup and daily operation. With flexible networking, precise wireless management, and support for extensive multi-channel systems, it is well suited for sound engineers, production companies, educational facilities, houses of worship, and corporate installations requiring reliable digital wireless audio.
