Shure BETA 87C Vocal Microphone

About: Shure BETA 87C Vocal Microphone

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.

Features:

• Smooth, wide frequency response with slight presence rise
• Uniform cardioid polar pattern for maximum isolation
• Minimum off-axis tone coloration
• Low-frequency roll-off compensates for proximity effect
• Three-stage pop filter minimizes breath pop and noise
• Break-resistant stand adapter
• Frequency response: 50 - 20,000 Hz

Specifications:

Transducer Type

Condenser (electret bias)

 

Frequency Response

50 to 20,000 Hz

 

Polar Pattern

Cardioid

 

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)

 

Self-Noise

22 dB typical, A-weighted

24 dB typical, weighted per DIN 45 405

(equivalent sound pressure level; measured with true rms voltmeter)

 

Dynamic Range

117 dB (maximum SPL to A-weighted noise level)

 

Hum Sensitivity

-5 dB equivalent SPL, maximum, in a 1 mOe field (60 Hz)

 

Signal-to-Noise Ratio

72 dB at 94 dB SPL (IEC 651)*

*S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted.

 

Polarity

Positive pressure on diaphragm produces positive voltage on pin 2 relative to pin 3 of the output connector.
