The Shure Beta 58A dynamic microphone is precision-engineered for vocals in professional live sound reinforcement and studio recording applications. A tailored frequency response accentuates the clarity of vocals, and a tight, supercardioid pickup pattern ensures high gain before feedback, maximum sound isolation, and minimum off-axis tone coloration.
The Beta 58A is ideal for close-up lead and background vocals, especially in high sound pressure level (SPL) environments. A proven shock mount system, hardened steel-mesh grille, and superior build quality withstand the rigors of daily sound reinforcement.
On stage or in the studio, the Beta 58A is made for refined voice. The brightened midrange and bass roll-off give lead and background vocals a mighty presence in the mix. And the supercardioid pattern works harder to isolate your sound from every other source in the air.
