Shure ULXD4Q Quad-Channel Digital Wireless Receiver — V50 (174–216 MHz)
ULXD4Q Overview
The Shure ULXD4Q is a professional quad-channel digital wireless receiver built for demanding sound reinforcement environments where channel density and spectral efficiency are critical. Designed around the ULX-D Digital Wireless platform, it delivers four independent channels of uncompressed digital audio in a single 1U rack space, making it an efficient solution for large-scale live production, broadcast, and installed sound applications. The V50 band covers 174–216 MHz, with wide tuning bandwidth up to 166 MHz depending on region, providing substantial frequency coordination flexibility. Audio engineers, system integrators, and touring companies requiring reliable multi-channel wireless operation will find the ULXD4Q a capable and scalable platform.
The ULXD4Q supports advanced antenna and spectrum management options alongside AES256 encryption, addressing both RF coordination complexity and secure audio transmission requirements in a single chassis.
