Shure BETA 57 Dynamic Supercardioid Microphone
Shure BETA 57 Dynamic Supercardioid Microphone
The Beta 57 is a premium quality supercardioid, dynamic microphone, ideal for musical instrument applications. A superefficient magnetic circuit design utilizing a neoÂdymium magnet provides maximum output voltage for improved signal-to-noise ratio in recording and sound reinforcement applications. Unlike many other superÂcardioid microphones, the Beta 57 retains a true superÂcardioid -(unidirectional) pickup pattern throughout its frequency range.
Features:
- Wide and smooth frequency response adds extra clarÂity and naturalness to microphone pickup
- High efficiency magnetic circuit using neodymiumÂiron-boron magnet increases output, maximizes signalÂto-noise ratio with any amplifier
- Supercardioid pattern remains uniform and symmetriÂcal throughout the microphone’s frequency range to reduce off-axis coloration and feedback, while improvÂing separation from other sound sources
- Improved pop protection compared to other instrument microphones
- Unique and stylish grille of extra-rugged chrome-plated steel
- Humbucking coil permits use even in strong hum fields produced by lighting and power equipment
- Advanced electro-pneumatic shock mount design effec-tively minimizes transmission of handling or stand noise
- Extremely rugged and durable
- Admirable performance in the studio or on stage
- Legendary Shure reliability for years of trouble-free performance
