{"product_id":"shure-adx-hh-470-616-mhz","title":"Shure ADX2\/SM58 – Handheld Wireless Transmitter, 470-616 MHz (G57)","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe Shure ADX2\/SM58 is a handheld wireless microphone transmitter built for commercial AV, broadcast, and live-event deployments that require dependable RF performance in the 470-616 MHz (G57) band. Pairing the industry-standard SM58 cardioid dynamic capsule with Shure's Axient Digital wireless platform, this transmitter is the right choice for integrators specifying a commercial AV wireless microphone system for regions or installations governed by the G57 frequency allocation. ShowLink remote control and AES 256-bit encrypted digital transmission make it suitable for conference room, house of worship, and broadcast environments where signal security and mid-show adjustability matter. This specific 470-616 MHz variant is a distinct SKU from the 606-663 MHz and 941-960 MHz Axient Digital handheld transmitter options, so integrators should confirm regional frequency compliance before specifying.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe ADX2\/SM58 extends Shure's Axient Digital wireless microphone lineup with a handheld transmitter tuned to the 470-616 MHz (G57) band, giving system designers a frequency-compliant option for markets and venues where this range is licensed for wireless audio use. Built around the SM58 cardioid dynamic capsule, the transmitter delivers the vocal clarity and off-axis rejection AV integrators expect from this microphone in corporate and institutional settings. The cast aluminum housing and internal helical antenna are engineered for daily use in commercial meeting spaces, training rooms, and broadcast studios where equipment gets moved, passed between presenters, and stored between events. ShowLink technology allows a technician to adjust gain, RF power, and other transmitter parameters remotely, without walking on stage or interrupting a presentation. Two transmission modes, Standard and High Density, let integrators tune coordination between maximum operating range and channel count depending on how many wireless mics are running in the same room. Infrared sync speeds up channel assignment during setup and teardown for multi-purpose rooms and rental\/staging applications. The transmitter charges on contacts compatible with Shure's SBC240 and SBM920 charging accessories, supporting rack-mounted charging stations in AV equipment racks. Because this SKU is fixed to the 470-616 MHz band, it should be paired with an Axient Digital receiver and other system components tuned to the same G57 frequency range for proper RF coordination. Typical buyers include AV integrators outfitting boardrooms and all-hands rooms, broadcast facilities standardizing on Axient Digital, and government or institutional procurement teams sourcing frequency-compliant wireless microphone systems for a defined region.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSM58 Cardioid

the ADX2\/SM58 (470-616 MHz) compatible with other Axient Digital components?\u003c\/strong\u003e\u003cbr\u003eYes, but the receiver and any other paired transmitters must be tuned to the same 470-616 MHz (G57) frequency band.
