Shure Beta 58A Handheld Supercardioid Dynamic Microphone - BETA 58A

Product Overview

The Shure Beta 58A is a professional-grade supercardioid dynamic vocal microphone designed for live sound reinforcement and studio recording. With a frequency response tailored for close-miked vocals—featuring a brightened midrange and bass rolloff to control proximity effect—and a uniform supercardioid polar pattern for high gain before feedback, it has become a standard professional vocal microphone on stages and in installed sound systems worldwide. Its hardened steel mesh grille, neodymium magnet capsule, and advanced shock mount system deliver the durability and performance that commercial AV integrators and live sound professionals require.

Product Description

The Beta 58A supercardioid pattern provides tighter off-axis rejection than a standard cardioid microphone, reducing pickup of monitors, adjacent sources, and room reflections—a practical advantage in live sound environments where feedback control and source isolation are priorities. The neodymium magnet delivers a high signal-to-noise output level, ensuring strong input signal to PA systems and mixers without excessive preamp gain. The pneumatic shock mount system attenuates mechanical noise and vibration transmitted through the mic stand, keeping handling artifacts out of the signal chain. The hardened steel mesh grille maintains structural integrity through consistent professional use in live event environments. Includes a 25D adjustable stand adapter, a 5/8-to-3/8-inch thread adapter, and a storage bag.

Key Features

• Supercardioid Polar Pattern — Provides tighter off-axis rejection than cardioid designs, delivering higher gain before feedback and better isolation from monitors and adjacent sources in live sound environments.
• Brightened Midrange with Bass Rolloff — Frequency response tailored for close-miked vocal reinforcement, adding presence and clarity while controlling proximity effect as the vocalist works near the capsule.
• Neodymium Magnet Capsule — Provides a high signal-to-noise output level for a dynamic microphone, reducing the preamp gain required from mixing consoles and installed DSP systems.
• Hardened Steel Mesh Grille — Resists wear, deformation, and abuse from regular use in live performance and rental environments without compromising acoustic performance.
• Advanced Pneumatic Shock Mount — Minimizes transmission of mechanical noise and vibration from mic stands and handling, maintaining clean signal in live and installed sound applications.
• Frequency Response: 50–16,000 Hz — Optimized for vocal reinforcement with a presence boost that helps cut through a live mix without requiring excessive EQ correction at the console.
• Uniform Supercardioid Pattern Across Frequency Range — Consistent polar response regardless of frequency simplifies positioning and ensures predictable behavior in live and reinforced environments.
• Includes Stand Adapter and Storage Bag — Ships with an A25D adjustable stand adapter, a 5/8-to-3/8-inch thread adapter, and a 26A21 storage bag for professional deployment readiness out of the box.
