The Shure Beta 57A® is a high output supercardioid dynamic microphone designed for professional sound reinforcement and project studio recording. It maintains a true supercardioid pattern throughout its frequency range. This insures high gain-before-feedback, maximum isolation from other sound sources, and minimum off–axis tone coloration.
Excellent for acoustic and electric instruments as well as for vocals, the extremely versatile Beta 57A dynamic microphone provides optimal warmth and presence. Typical applications include drums, guitar amplifiers, brass, woodwinds and vocals.
Tailored frequency response provides drums, guitars, vocals, and horns with studio quality sound
Uniform supercardioid pattern for high gain-before-feedback and superior rejection of off–axis sound
Hardened steel mesh grille that facilitates use of proximity effect and resists wear and abuse
Neodymium magnet for high signal–to–noise ratio output
Minimally affected by varying load impedance
Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration
Legendary Shure quality and reliability
Dynamic (moving coil)
50 to 16,000 Hz
Supercardioid, rotationally symmetrical about microphone axis, uniform with frequency.
Polar Output Level (at 1,000 Hz)
Open Circuit Voltage -51 dBV/Pa* (2.8 mV) *1 Pa = 94 dB SPL
Rated impedance is 150 ohms (290 ohms actual) for connection to microphone inputs rated low Z.
Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3.
