The Shure Beta 57A has a tailored frequency response providing warmth and presence whilst maintaining 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. The hardened shell mesh grille facilitates use of proximity effect as well as resisting wear and abuse. 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 Specifications Transducer Type: Dynamic Polar Pattern: Supercardioid Frequency Response: 50 Hz - 16 kHz Sensitivity (1 kHz): -51 dBV/Pa / 2,8 mV/Pa Weight: 275 g
