Compatible with Axient® Digital Wireless Systems, the Shure AD2/B58A Handheld Transmitter is a wireless microphone transmitter that equips you with professional-caliber audio and enhanced RF performance—no matter what your application. Boasting a Beta 58A microphone capsule, this transmitter is ideal for capturing vocals. Its design is characterized by a backlit LCD with an intuitive menu and controls as well as a low-profile, lockable power switch.
Choose between two transmission modes: Standard Mode optimizes wireless coverage, while High Density Mode intensifies the coverage and maxes out the system’s channel count. Other features include wide tuning up to 184 MHz, an included detachable ¼-wave antenna, and secure transmission via its encryption enabling. Use the included pair of AA batteries, or opt for the compatible SB900B lithium-ion rechargeable batteries (sold separately). The transmitter’s housing incorporates external contacts for dock charging (dock unit sold separately).
The AD2’s rugged metal construction allows it to take the punishment of the most demanding stages, while its black finish blends seamlessly into virtually any environment. It comes with a zippered bag, a brass adapter, a black swivel adapter, two AA alkaline batteries, and a battery contact cover.
Note: When purchasing separate wireless components, please match their frequency bands to ensure proper system operation.
