Description
The Shure ULXD4Q Quad-Channel Digital Wireless Receiver delivers enterprise-grade wireless audio performance for demanding A/V environments, large venues, and mission-critical installations. Designed to house four independent receivers in a single rack unit, this system provides exceptional spectrum efficiency, scalability, and reliability.
Operating within the G57 frequency band (470 to 608 MHz), the ULXD4Q features an ultrawide 138 MHz tuning range, enabling deployment of up to 60 channels in a single location. With Digital Predictive Switching Diversity, the system ensures stable RF performance and minimizes dropouts even in congested environments.
Dual Ethernet ports support Dante digital audio networking for seamless integration into modern AV-over-IP workflows, while RF cascade ports allow efficient antenna distribution across multiple units. Built-in AES-256 encryption secures transmissions, making it ideal for corporate, government, and high-security applications.
With pristine 24-bit/48 kHz audio, wide dynamic range, and low latency, the ULXD4Q delivers clear, natural sound reproduction. Intelligent features such as automatic frequency scanning, gain optimization, and remote control via ShurePlus Channels simplify deployment and system management at scale.
