The AD2/B58 comes equipped with a Beta 58A dynamic capsule designed for close-up vocals, with brightened midrange and bass roll-off to control proximity effect. The capsule features a supercardioid polar pattern that ensures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration
- Standard and High Density transmission modes
- Encryption-enabled, secure transmission
- Backlit LCD with easy-to-navigate menu/controls
- Low-profile, lockable power switch
- AA or SB900A lithium-ion rechargable batteries for convenient power options
- Audio Frequency Response: 50 - 16,000 Hz
- Optimized frequency response controls proximity effect and adds extraclarity to speech or vocals
- High-efficiency magnetic circuit using neodymimu-rion-boron magnetincreases output, maximizes signal-to-noise ratio with any amplifier
- True supercardioid pattern remains uniform and symmetrical throughtout thevocal range to reduce feedback, off-axis coloration, and unwanted backgroundnoise
- Effective ball-type filter of extremely rugged construction reduces pop(explosive breath sounds) when used close to the mouth, and wind noise whenused outdoors
- Humbucking coil permits use even in strong hum fields due to lighting andpower equipment
- Advanced electro-pneumatic shock mount design effectively miminizestransmission of handling or stand noise
- Excellent performance for demanding live vocal applications
