The Shure BETA 57A is a high-output supercardioid dynamic microphone engineered for professional live sound reinforcement and studio recording of instruments and vocals. Introduced in 1996 as part of Shure’s premium BETA series (building on the original Beta 57 from 1989), it features a neodymium magnet, tailored midrange presence, and exceptional isolation—making it the go-to choice for close-miking guitar amps, snare drums, brass, woodwinds, and percussion. Its rugged, compact design and uniform supercardioid pattern deliver clean, detailed sound with minimal bleed, even on the loudest stages.
