Essential Information About the Shure Beta 57A Supercardioid Dynamic Microphone



  • Constant supercardioid directivity for high gain before feedback and excellent isolation of nearby sources.

  • Stage/studio versatility: ideal for drums, electric guitars, wind instruments, and vocals.

  • Professional durability: hardened steel grille and pneumatic shock mount system to reduce mechanical noise and vibrations.

  • Neodymium magnet capsule offering a high signal-to-noise ratio and low sensitivity to load impedance variations.



A Beta Series Reference for Both Stage and Studio


Designed for professional sound reinforcement and recording, the Shure Beta 57A follows the line of "Beta" microphones renowned for their precision and durability. Its true supercardioid pattern is maintained across the entire useful frequency range, reducing off-axis coloration and facilitating demanding placements on dense stages.

Who Is It For and What Are Its Uses?


The Beta 57A is aimed at sound engineers, musicians, and touring technicians seeking a compact dynamic microphone capable of switching from a tom to a snare drum, from a guitar cabinet to a saxophone, while delivering clear vocal reproduction. Its isolation and resistance to feedback make it a reliable ally on noisy stages as well as in booths.

Design and Key Performance Features



Controlled Directivity and Proximity Effect Management


The newly designed grille optimizes the use of the proximity effect to thicken the low end without excess. The tight supercardioid pattern improves source focus and side rejection, contributing to a cleaner mix.

Shure Durability and Reliability


The silver-blue enameled die-cast body and matte spherical hardened steel grille withstand the rigors of touring. The pneumatic shock mount limits the transmission of handling noise, while low sensitivity to impedance variations ensures stable performance across different systems.
