The Shure ADX2FD/SM58 is a professional handheld wireless microphone system that pairs the iconic SM58 dynamic capsule with the high-redundancy dual-channel transmission of the Axient Digital platform. This product is engineered for applications where legendary vocal durability and absolute wireless reliability are demanded in equal measure. The SM58 capsule is renowned worldwide for its rugged construction, tailored vocal response with a pronounced presence boost, and exceptional ability to reject handling noise and control feedback. This makes it a perennial favorite for live vocal performance across countless genres and environments.

The transmitter body incorporates the advanced ADX2FD electronics, which provide true dual-channel wireless transmission. This means the microphone broadcasts the same audio signal on two separate radio frequencies simultaneously to a compatible dual-channel receiver. This system creates a seamless redundancy; if interference degrades the primary signal, the receiver can switch to the backup transmission instantly and without any audible dropout. This level of fail-safe operation is critical for high-profile live broadcasts, stadium tours, and major events where a wireless failure would be catastrophic. The system also supports full Axient Digital features like remote ShowLink control and sophisticated spectrum management.

Built to the highest professional standards, the transmitter features a durable metal body, a legendary steel grille, and a clear OLED display. It is powered by a high-capacity rechargeable lithium-ion battery. The ADX2FD/SM58 represents the culmination of Shure's legacy in transducer design and wireless innovation, offering performers the trusted, road-proven sound of the SM58 with the peace of mind provided by the most robust and intelligent wireless transmission technology available for live sound.
