The Shure Beta 87A vocal microphone is precision-engineered to deliver an exceptionally smooth frequency response in a supercardiod condenser design. Built to withstand extreme sound pressure levels (SPL), the Beta 87A is ideal for professional sound reinforcement and studio recording applications.


The tailored frequency response, combined with a controlled low-frequency roll-off, makes this microphone ideal for close-up lead and background vocals—especially in high SPL environments. An advanced cartridge shock mount system, hardened steel-mesh grille, and superior build quality withstand the rigors of daily touring and sound reinforcement. The Shure Beta 87A is available to hire from HD Production now.
