Product Specifications
Beta 58A Supercardioid Dynamic Vocal Microphone

Overview

The Shure Beta 58A dynamic vocal microphone is precision-engineered for professional live sound reinforcement and studio recording applications. A tailored frequency response accentuates clarity of vocals and a tight supercardioid pattern insures high gain-before-feedback, maximum isolation from other sound sources and minimum off-axis tone coloration.

Features

Premier live performance microphone with Shure quality, ruggedness, and reliability Uniform supercardioid pick-up pattern for maximum gain before feedback and superior rejection of off-axis sound Tailored frequency response specifically shaped for vocals, with brightened midrange and bass roll off to control proximity effect Neodymium magnet for greater sensitivity and higher output Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration Dent-resistant steel mesh grille and enamel coated die-cast metal construction resist wear and abuse Effective built-in pop filter reduces undesirable wind and breath noise
