MODEL BETA 57A SUPERCARDIOID DYNAMIC MICROPHONE DESCRIPTION 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 ensures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration. A completely new grille design lets you take better advantage of proximity effect. The BETA 57A is an exceptionally versatile microphone. Typical applications include drums, guitar amplifiers, brass, woodwinds and vocals. Features Tailored frequency response with a studio-quality sound for drums, guitars, vocals, and horns 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 SPECIFICATIONS Type Dynamic (moving coil) Frequency Response 50 to 16,000 Hz (see Frequency Response, page 2) Polar Pattern Supercardioid, rotationally symmetrical about microphone axis, uniform with frequency (see Polar Patterns, page 2)
