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.FeaturesTailored frequency response provides drums, guitars, vocals, and horns with studio quality soundUniform supercardioid pattern for high gain-before-feedback and superior rejection of offaxis soundHardened steel mesh grille that facilitates use of proximity effect and resists wear and abuseNeodymium magnet for high signaltonoise ratio outputMinimally affected by varying load impedanceAdvanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibrationLegendary Shure quality and reliabilitySpecsMicrophone Type: DynamicPolar Pattern: SupercardioidFrequency Response: 50Hz-16kHzOutput Impedance: 150 ohmsColor: Dark GreyConnector: XLRWeight: 0.6 lbs.
