The Shure SM58
is a professional cardioid dynamic microphone
, commonly used in live vocal applications. Produced since 1966 by Shure Incorporated
, it has built an enviable reputation among musicians for its robust construction and technical performance, and is considered the industry standard for live performance microphones.Live Sound International
, September/October 2002. The SM58 is one of the best-selling microphones in the world. The SM
stands for Studio Microphone.
Like all directional microphones, the SM58 is subject to proximity effect
, a low frequency boost when used close to the source. The cardioid response reduces pickup from the side and rear, helping to avoid feedback onstage. It uses the balanced XLR
three-pin connection. There are wired (with and without on/off switch) and wireless
versions. The microphone has a frequency response extending from 50 Hz to 15 kHz. The SM58 uses an internal shock mount to reduce handling noise.
