Shure SM58
From Wikipedia, the free encyclopedia
The Shure SM58 is a professional cardioid dynamic microphone, commonly used in live vocal applications. It has a legendary reputation for its ruggedness. Introduced in 1966, the SM58 remains one of the best selling microphones in the world today. The SM58 has a mid-bass frequency boost common to all cardioid microphone designs. It has, like almost every professional microphone, an XLR connector. There are wired (with and without on/off switch) and wireless versions. The microphone has a frequency response from 50 Hz to 15 kHz. The MSRP for this model is $188. The SM58 capsule is also available with many Shure wireless systems.
The SM58 uses an internal shock mount to reduce handling noise.
While the look and intended applications are similar, the Beta 58 and Beta 58A have little in common with the SM58. The Beta series utilizes a different capsule and transformer to the SM series. The Beta 58A has an extended frequency response and it is also super cardioid instead of cardioid giving improved side rejection.
