Characteristics
The SM57 uses a capsule similar to that of the popular SM58, but has some mechanical and acoustical differences. Like the SM58, the SM57 is fitted with an XLR connector and features a balanced output, which helps to minimize electrical hum and noise pickup. According to Shure, the frequency response extends from 40 Hertz (Hz) to 15 kHz. The SM57 is manufactured in the USA, Mexico, and China.
The Shure A2WS is an accessory windscreen for the SM57 that attenuates wind noise and plosives ("pop" sounds), and protects the microphone capsule.
