Shure 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. 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.
Beta 58A vs SM58 - What's the difference?
Firstly, the polar pattern. The SM58 has a cardioid polar pattern, whilst the Beta 58A's is supercardioid. This gives the Beta better side-rejection, and the SM better rear-rejection. However, supercardioid also gives more directionality, and is much-less susceptible to feedback when positioned correctly. The Beta 58A also features a Neodymium magnet, providing higher sensitivity and an output that is 4dB hotter than the SM58.
There's also a difference in frequency response. The Beta boasts a slightly extended low and high-end, which provides extra detail and definition to the SM. And with a new advanced pneumatic shock-mount system, the Beta 58A also offers lower handling and mechanical noise.
