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

Break-resistant stand adapter

Transducer Type

Condenser (electret bias)


Frequency Response

50 to 20,000 Hz


Polar Pattern



Output Impedance

Rated at 150 ohms (100 Ohms actual +/- 20%)

Recommended minimum load impedance: 800 ohms


Sensitivity (at 1,000 Hz)

Open Circuit Voltage: -51 dBV/Pa (2 mV)

(1 Pa = 94 dB SPL)>


Output Clipping Level

1000 Ohm Load at 1,000 Hz: -6 dBV (0.5 V)


Maximum SPL

139 dB at 1,000 Hz (0.25% THD, 1000 Ohm load)



22 dB typical, A-weighted
