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

superior rejection of offaxis sound
Neodymium magnet for high signaltonoise output
Hardened steel mesh grille that resists wear and abuse
Advanced pneumatic shock mount system that minimizes transmission
of mechanical noise and vibration
