The Shure Beta 87A is a supercardioid condenser vocal microphone designed to deliver smooth, detailed, and consistent vocal reproduction in professional live sound, broadcast, and studio environments. It features an extended 50 Hz–20 kHz frequency response with a gentle presence rise that helps vocals cut through a mix without harshness, and an electronically controlled low‑frequency roll‑off that prevents the boominess associated with close‑miking. Its tight supercardioid pattern provides excellent isolation from nearby instruments and stage noise, offering strong gain before feedback and minimal off‑axis coloration. Built to handle high sound‑pressure levels up to about 140 dB, the Beta 87A maintains low distortion and a wide dynamic range around 117 dB, while its internal shock mount and steel mesh grille reduces handling noise. With a sensitivity of roughly –52.5 dBV/Pa, 150‑ohm output impedance, and phantom‑power operation (11–52 V), it delivers the clarity of a studio condenser in a rugged handheld form ideal for lead and background vocalists.
