The Shure Beta 58A is a Supercardioid Dynamic with High Output Neodymium Element for Vocal Applications In the tradition of the SM58, the Shure Beta 58A dynamic microphone has become a top choice among vocalists and touring sound professionals. The Shure Beta 58A is a high-output supercardioid dynamic vocal microphone designed for professional sound reinforcement and project studio recording. It 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 Shure 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. Typical applications for the Beta 58A include lead vocals, backup vocals and speech.
