The Shure Model BETA 87A is a premium quality supercardioid hand-held electret condenser vocal microphone with exceptionally smooth frequency response and high sound pressure level (SPL) capability. Used for professional sound reinforcement, broadcasting, and studio recording applications, the BETA 87A combines superb performance with the ruggedness needed for touring and field production. The BETA 87A features a controlled low-frequency roll-off that compensates for proximity effect and prevents the boomy sound often associated with close pick-up. The characteristic Shure presence rise brightens the upper midrange. The tight supercardioid pattern, with null points at approximately 125, provides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. The BETA 87A operates on phantom power.FeaturesDurable, and great sounding handheld condenser micTuned for live vocalsGreat noise and feedback rejectionBuilt like a tankLow handling noiseFull-range frequency response (50Hz-20kHz)Requires +48V phantom powerSpecsMicrophone Type: CondenserPolar Pattern: SupercardioidFrequency Response: 50Hz-20kHzMax SPL: 140.5dBOutput Impedance: 150 ohmsSignal to Noise Ratio: 70.5dBSelf Noise: 23.5dB (A weighted)Color: GreyConnector: XLRWeight: 0.48 lbs.Included Accessories: Mic Clip, Carrying Pouch
