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
