The Shure ULXD4-GV is a single-channel digital wireless receiver from the ULX-D series, specifically configured with always-on 256-bit AES encryption for secure audio transmission. This receiver is engineered for environments where the confidentiality of audio content is paramount, such as government, military, corporate boardrooms, legal proceedings, and secure broadcast applications. The encryption is applied at the transmitter and decoded at the receiver, ensuring that the wireless signal cannot be intercepted and understood by unauthorized third parties. Beyond security, it delivers the full audio fidelity and robust performance of the ULX-D platform, with 24-bit digital audio, a wide dynamic range, and very low latency.

The receiver features a bright, high-resolution display for monitoring RF and audio levels, frequency, and encryption status. It is compatible with the full range of ULXD transmitters (handheld and bodypack) that are also configured for encryption. The unit supports remote control and monitoring via Ethernet when integrated with Shure's Wireless Workbench software, allowing for centralized frequency coordination and system management. Its single-channel design is ideal for critical, standalone wireless links or as part of a larger, multi-receiver secure system. The robust metal construction ensures reliability for both touring and installed use.

For security-conscious organizations, the ULXD4-GV provides a turnkey solution for wireless audio that does not compromise on sound quality or operational features. It addresses the growing need for secure wireless communication in sensitive settings, offering peace of mind that private conversations and classified information remain protected while leveraging the industry-leading performance and reliability of Shure's digital wireless technology.
