Description
The Shure ULXD4Q Quad-Channel Digital Wireless Receiver delivers enterprise-grade wireless audio performance for large-scale A/V installations, live venues, and mission-critical environments. Designed as part of the ULX-D digital wireless ecosystem, this rackmount receiver integrates four independent channels into a single 1RU chassis, enabling high-density deployments with exceptional RF stability and audio clarity.
Operating in the J50A frequency band (572 to 608 MHz and 614 to 616 MHz), the ULXD4Q supports up to 60 simultaneous channels with a wide 44 MHz tuning range, making it ideal for complex multi-system setups. Advanced Digital Predictive Switching Diversity ensures reliable signal integrity by proactively avoiding interference and dropouts.
With AES-256 encryption, Dante digital audio networking, and dual Ethernet ports, this receiver is built for secure, scalable, and networked audio environments. Each channel features independent gain control, XLR outputs, and real-time RF/audio metering, while audio summing allows the unit to function as a 4-channel mixer when needed.
Engineered for professional workflows, the ULXD4Q simplifies system coordination, monitoring, and control through network integration and intuitive front-panel operation, delivering pristine 24-bit/48 kHz audio performance across demanding applications.
