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
