Shure B58 Microphone Dynamic Supercardioid Beta 58
The Beta 58 is a premium quality, supercardioid, dynamic vocal microphone. A superefficient magnetic circuit design utilizing a neodymium magnet provides maximum output voltage for improved signal-to-noise ratio in stage monitor and sound reinforcement applications. Unlike many other supercardioid microphones, the Beta 58 retains a true supercardioid pattern throughout its frequency range. This insures minimum tone coloration when the performer moves off axis, and produces maximum isolation from other vocalists or instruments.
Features:
- Humbucking coil permits use even in strong hum fields due to lighting and power equipment
- Advanced electro-pneumatic shock mount design effectively minimizes transmission of handling or stand noise
- Extremely strong and durable; carefully balanced for handheld use
- Excellent performance for demanding live vocal applications
- Legendary Shure reliability for years of trouble-free performance
