Shure Beta58A Supercardioid Dynamic Vocal Microphone

The Shure Beta 58A is a handheld supercardioid dynamic microphone offering enhanced midrange and controlled proximity effect for optimal reproduction of vocals, speech, and instruments in concerts, public address, houses of worship, and live stage applications. Its dynamic capsule utilizes a neodymium magnet for high signal-to-noise levels and is shock-mounted to reduce handling noise. It requires no power source and delivers a frequency response of 50 Hz to 16 kHz with a gentle boost above 3 kHz.

The supercardioid polar pattern is maintained across the mic's frequency range, allowing it to consistently reject sound at its off-axis points and deliver high immunity to feedback. The XLR 3-pin output ensures compatibility with most microphone preamps, mixer inputs, and portable PA systems.
