The Shure ULXD4D-GV is a high-performance, dual-channel digital wireless receiver engineered for professional applications that demand exceptional audio quality, robust RF management, and uncompromising signal security. Operating in the GV frequency band, which is optimized for specific regional spectrum allocations, this receiver simultaneously manages two independent wireless microphone channels within a compact half-rack width unit, making it an efficient choice for installations where space is at a premium. It leverages Shure's advanced digital transmission technology to deliver audio with a wide dynamic range, ultra-low latency, and crystal-clear fidelity, ensuring perfect synchronization with other audio sources in broadcast, live sound, and corporate AV environments. A critical, non-negotiable feature is its always-on 256-bit AES encryption, which secures the audio signal from the paired transmitters to the receiver, providing essential protection against eavesdropping and unauthorized interception for sensitive governmental, corporate, and broadcast communications.

The receiver is designed with a comprehensive suite of RF coordination and monitoring tools to ensure reliable operation in challenging wireless landscapes. It is fully compatible with Shure's Wireless Workbench software, enabling system-wide frequency planning, remote monitoring of RF and audio levels, and detailed diagnostics from a central computer. The front panel features a bright, high-resolution color display and intuitive navigation controls, providing real-time visibility into both channels' status, battery life of linked transmitters, and RF signal strength. Each channel can be quickly and accurately linked to ULXD1 or ULXD2 series transmitters via infrared synchronization, and the unit supports automatic frequency selection to find the clearest available channels. As a standard feature, it includes Dante digital audio networking, allowing for seamless, multi-channel digital audio distribution over an Ethernet network and straightforward integration into modern digital audio workstations and routing systems.

Built for reliability in mission-critical settings, the ULXD4D-GV features true diversity reception with dual antenna inputs, robust metal construction, and an efficient design that minimizes heat output. Its half-rack form factor allows two units to be mounted side-by-side in a single 1U rack space, offering high channel density. By combining secure, encrypted digital audio, sophisticated RF intelligence, and professional networking capabilities in a space-efficient design, the Shure ULXD4D-GV provides audio professionals with a powerful, secure, and future-proof foundation for building critical wireless microphone systems where audio integrity and security cannot be compromised.
