Shure Beta 58A Microphone

Shure Beta 58A Dynamic Vocal Microphone (Supercardioid)

The Shure Beta 58A is a high-output dynamic microphone designed for professional sound reinforcement and studio recording. This model has become the first choice for lead and backup vocalists worldwide. Unlike the standard SM58, the Beta 58A features a supercardioid polar pattern, which ensures maximum isolation from other stage sounds and allows for higher gain-before-feedback.

The microphone features a specially shaped frequency response that emphasizes vocal clarity and adds brightness, while a low-frequency roll-off controls the proximity effect. Thanks to its neodymium magnet, the microphone offers high sensitivity and an excellent signal-to-noise ratio. The robust metal construction and hardened steel mesh grille protect the capsule from damage, while the advanced pneumatic shock mount system minimizes mechanical noise when holding the microphone.
