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.
