The
Shure SM58 microphone
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 more than four decades later it is still considered the industry standard for live vocal performance microphones.[1] The SM58 is one of the best-selling microphones in the world. The SM stands for Studio Microphone.[2]
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 SM58 uses an internal shock mount to reduce handling noise.
