The Shure UR2-G1 is a professional handheld wireless transmitter operating in the 470-530 MHz UHF band, forming a core component of the Shure UHF-R series wireless microphone systems. It is engineered to provide exceptionally reliable, high-fidelity wireless audio transmission for the most demanding live performance, broadcast, and installed sound applications. This transmitter integrates a high-quality microphone capsule—the specific model varies (e.g., it can house a KSM9 condenser capsule or others depending on configuration)—directly into a robust metal body, delivering the sonic performance of a premium wired microphone with the freedom of wireless operation. Its advanced design focuses on maximizing RF stability, battery efficiency, and user control in complex wireless environments.

Key to its performance is the UHF-R system's sophisticated feature set, which includes automatic frequency scanning and selection to avoid interference, along with user-adjustable RF power output to optimize range and battery life for the specific venue. The transmitter features an intuitive backlit LCD screen that displays critical information such as operating frequency, selected channel, RF and audio levels, and detailed battery status. It is powered by two AA batteries, offering extended runtime, and supports compatibility with Shure's rechargeable battery systems. Advanced networking capabilities allow the transmitter to be remotely monitored, controlled, and grouped with other UHF-R components via system management software, a crucial feature for large, multi-channel wireless setups.

Built to the rugged standards required for touring, the UR2-G1 transmitter is designed to withstand the physical demands of nightly use. It represents the professional benchmark for wireless handheld transmitters, trusted by audio engineers for major concert tours, television broadcasts, and high-profile corporate events. By combining premium acoustic performance with bulletproof wireless technology and comprehensive system control, it ensures that vocal performances are captured with clarity and transmitted with unwavering reliability, free from dropouts and interference.
