Shure Beta 58A

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.

Features
•	Frequency response tailored for vocals, with brightened midrange and bass rolloff to control proximity effect
•	Uniform supercardioid pattern for high gain before feedback and superior rejection of off–axis sound
