Beta 58A Vocal Microphone



The Shure Beta 58A is a high-output supercardioid dynamic vocal microphone designed for professional sound reinforcement and project studio recording. It has become a leading choice among vocalists and touring professionals worldwide.



The Beta 58A maintains a true supercardioid pattern throughout its frequency range. This insures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration. The Beta 58A has a shaped frequency response that is ideal for close up vocals. The superb performance of this microphone is not affected by rough handling because of its rugged construction, proven shock mount system, and hardened steel mesh grille.
