The Shure UR2 is a professional handheld wireless transmitter, a core component of the high-end UHF-R series wireless microphone systems, designed for mission-critical applications in live performance, broadcast, and installed sound. It integrates a high-quality microphone capsule—the specific model varies depending on configuration (such as the SM58, Beta 58, or KSM9)—into a robust metal body, delivering the sonic performance of a premium wired microphone with the freedom of wireless operation. The transmitter operates on user-selectable UHF frequencies within its designated band, providing a stable, interference-resistant link to compatible UHF-R receivers. It is engineered with advanced RF circuitry and companded audio transmission to ensure clear, reliable audio with minimal latency.

A key feature of the UR2 is its sophisticated user interface and integration into the UHF-R system ecosystem. It includes a backlit LCD screen that displays critical information such as operating frequency, RF and audio levels, battery status, and system alerts. The transmitter offers adjustable RF output power to optimize range and battery life for the specific venue. It is powered by two AA batteries, providing extended runtime, and supports compatibility with Shure's rechargeable battery systems. The transmitter can be remotely monitored, controlled, and grouped with other system components via Shure's Wireless Workbench software when used with a networked UHF-R system, offering unprecedented control for large-scale productions.

Built to the rugged standards required for touring, the UR2 transmitter is designed for continuous, reliable operation. It is trusted by major sound companies, broadcasters, and theatrical productions worldwide for its bulletproof performance and comprehensive feature set. When paired with a UHF-R series receiver, it forms a complete, professional-grade wireless link that delivers crystal-clear audio with the reliability and system management features needed for applications where wireless failure is not an option.
