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
• Legendary Shure quality and reliability
• 2 year warranty

Specifications:

Type: Condenser (electret bias)

Polar Pattern: Cardioid

Sensitivity (at 1000 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)

Impedance: Rated at 150 ohms (100 Ohms actual +/- 20%). Recommended minimum load impedance: 800 ohms

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

Connector: Three-pin (XLR) professional audio

Case: Aluminum construction with painted blue metallic finish, and hardened steel grille with nickel satin chrome plating

Net Weight: 207g

Environmental Conditions:
Operating: -18 degrees to 60 degrees C (0 degrees to 135 degrees F)(relative humidity <90%)
Storage: -29 degrees to 74 degrees C (-20 degrees to 165 degrees F) (relative humidity <80%)
