Description
The Shure ULXD4Q Quad-Channel Digital Wireless Receiver delivers enterprise-grade wireless audio performance for large venues, broadcast environments, and professional AV installations. Housed in a single 1RU rackmount chassis, this system integrates four independent digital receivers, enabling high-density wireless deployment with exceptional clarity and reliability.
Operating in the H50 UHF band (534–598 MHz), the ULXD4Q provides a wide 64 MHz tuning range and supports up to 60 channels in coordinated environments. Advanced Digital Predictive Switching Diversity ensures stable RF performance by proactively preventing dropouts, while AES-256 encryption safeguards every transmission for secure applications.
Designed for scalability and networked control, the receiver features dual Ethernet ports with Dante digital audio networking, enabling seamless integration into modern AV infrastructures. Audio summing capability allows the unit to function as a 4-channel mixer, reducing the need for additional hardware.
With pristine 24-bit/48 kHz audio quality, flexible gain control, and intuitive front-panel monitoring, the ULXD4Q is engineered for mission-critical applications where performance, scalability, and reliability are non-negotiable.
