Shure ADX2/SM58 Wireless Handheld Microphone Transmitter

The Shure ADX2/SM58=-G57 is a microphone transmitter that offers handheld operation with digital wireless connectivity and delivers the familiar sound of the SM58 dynamic capsule. By working seamlessly with Axient Digital receivers, it gives singers, presenters, and audio engineers a tool they can trust when clarity and consistency matter most.

The unit provides a tuning range of 146 MHz, allowing production teams to find open frequencies even in congested RF environments. ShowLink technology keeps the signal stable by monitoring interference in real time and letting technicians adjust settings remotely, so the performer can stay focused on the show. When additional reach is required, users can choose 2, 10, or 40 mW of RF power to strike the right balance between range and battery life.

Power comes from the included SB920 rechargeable battery, which supports up to nine hours of continuous use. An aluminum housing that is both rugged and resistant to moisture handles the bumps, sweat, and weather that often accompany live events. The backlit LCD makes it easy to confirm battery status, frequency, and gain settings on a dark stage, and infrared sync speeds up pairing with a receiver during quick changeovers.

Whether it is a small club gig, a touring festival, a place of worship, or a corporate keynote, the ADX2/SM58=-G57 fits right in. Vocalists appreciate the cardioid pickup pattern that focuses on their voice while rejecting crowd noise, and front-of-house engineers value the automatic gain adjustment that keeps levels consistent from song to song.
