Excellent for touring professionals, the Beta 87C premium vocal microphone delivers studio-grade performance and a smooth, extended high-end frequency response in a cardioid condenser design.
The microphone adds warmth to the frequency response and creates an ideal environment for in ear personal monitoring. And its highly consistent cardioid pattern offers excellent rear rejection.
Vocalists who use earphone monitor systems such as Shure PSM™ will appreciate how effectively the BETA 87C rejects ambient sound from the rear of the microphone.
Leading the field for studio-quality sound in live performance, the Beta 87A and 87C have a smooth, tailored response for warm, accurate sound.
Smooth, wide frequency response, slight presence rise
Low-frequency roll-off compensates for proximity effect
Uniform cardioid polar pattern for maximum isolation
Minimum off-axis tone coloration
Three-stage pop filter minimizes breath pop and noise
