Shure AD2/B87A Digital Handheld Wireless Microphone Transmitter

The Shure AD2/B87A=-G57 is a handheld digital transmitter that pairs with Axient Digital receivers to deliver dependable, studio-grade wireless audio. Shure fits it with the Beta 87A supercardioid condenser capsule, so vocals cut through a busy mix while unwanted stage noise stays out of the signal. Whether you are fronting a band, presenting on a conference stage, or hosting a live broadcast, the capsule’s smooth response and strong rejection help every word land with clarity.

A wide 146 MHz UHF tuning range, along with selectable RF power levels of 2, 10, or 35 mW, gives engineers room to find clean frequencies even in crowded arenas. With a clear line of sight, performers can move up to 330 feet from the receiver without dropouts, making the system comfortable for large stages, worship platforms, and event venues that require long throw coverage.

Security has become as important as sound quality. The AD2/B87A meets that need with AES 256-bit encryption, so corporate meetings, worship services, and broadcasts stay private from start to finish. Power management is equally forward-thinking: add the optional SB900A lithium-ion battery to enjoy up to nine hours of run time and real-time charge readouts on the backlit LCD.

Tour-ready construction rounds out the package. A moisture-resistant aluminum body stands up to travel, weather changes, and quick hand-offs between performers. The capsule bay accepts any Shure interchangeable handheld capsule, so you can tailor the sound for different voices or genres without changing transmitters. Intuitive menu navigation and a bright display make last-minute tweaks easy, even under low stage light.
