The Shure ULXD4D Dual Channel Digital Wireless Receiver delivers uncompromising digital audio quality, rock-solid RF performance, and advanced networked control in a rugged 1RU all-metal chassis. Designed for professional sound reinforcement, broadcast, corporate AV, and mission-critical applications, the ULXD4D combines two fully independent digital receivers into a compact and efficient rack-mount solution.
Each channel offers independent gain control, audio and RF metering, and balanced XLR outputs with switchable mic/line level, allowing flexible signal routing or summed outputs. With Digital Predictive Switching Diversity, bodypack frequency diversity, and support for High Density mode, the ULXD4D ensures reliable performance even in crowded RF environments.
For modern networked systems, the ULXD4D features Dante™ digital audio over Ethernet, dual Ethernet ports for simplified system deployment, and full integration with Wireless Workbench® 6 for advanced frequency coordination, monitoring, and control. AES 256-bit encryption provides secure transmission for corporate, government, and broadcast use.
