Shure BETA 57A — Supercardioid Dynamic Instrument Microphone
BETA 57A Overview
The Shure BETA 57A is a supercardioid dynamic instrument microphone built for professional use on stage and in the studio. Designed specifically for close-miking amplified and acoustic instruments, it delivers high gain before feedback in demanding live environments where precise pattern control is critical. A neodymium magnet provides an elevated signal-to-noise ratio, ensuring clean, detailed reproduction even at high SPL. The BETA 57A is well suited for audio engineers, touring companies, houses of worship, and venue installations requiring a reliable, consistent instrument mic.
The compact grille design allows placement in tight miking positions, and the integrated shock mount minimizes the transmission of mechanical noise and stand vibration into the signal path.
Key Features
- Supercardioid Polar Pattern — Tight pickup pattern maximizes gain before feedback and reduces bleed from adjacent sources on crowded stages
- Neodymium Magnet — Provides a high signal-to-noise ratio for clean, detailed instrument reproduction
- High Gain Before Feedback — Engineered for demanding live environments where monitor levels and stage volume are elevated
- Steel Mesh Grille — Hardened construction resists denting and deformation under heavy touring conditions
- Integrated Shock Mount — Minimizes transmission of handling noise and stand vibration into the audio signal
- Compact Grille Design — Enables precise placement on amplifier grilles, drum kits, and acoustic instruments where space is limited
- Amplified and Acoustic Instrument Optimized — Voiced to handle the transient response and SPL demands of guitar cabinets, brass, woodwinds, and percussion
