SHURE SM57A BETA MICROPHONE.
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 guitar amps and speaker cabinets.
The extremely versatile Beta 57A dynamic microphone provides optimal
warmth and presence.
FEATURES:
- 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
