Microfon Vocal Beta 87A

Smooth frequency response with gradual presence rise
Highly consistent supercardioid polar pattern provides superior gain-before-feedback
Electronic low-frequency roll-off compensates for proximity effect
Wide dynamic range (117 dB) and low distortion characteristics
Very low susceptibility to RFI and electromagnetic hum
Advanced cartridge shock-mount system absorbs mechanical shocks and reduces handling noise
Built-in pop filter reduces undesirable wind and breath sounds
Legendary Shure quality and reliability

Cartridge Type: Condenser (electret bias)
Frequency Response: 50 to 20,000 Hz
Polar Pattern: Supercardioid
Output Impedance: Rated at 150 ohms (100 ohms actual +/- 20%); Recommended minimum load impedance: 800 ohms
Sensitivity (at 1,000 Hz): Open Circuit Voltage -52.5 dBV/Pa (2 mV); (1 Pa = 94 dB SPL)
Clipping Level (at 1,000 Hz): 1000 ohm Load: -6 dBV (0.5 V)
Maximum SPL (at 1,000 Hz): 140.5 dB (0.25% THD, 1000 ohm load)
Self-Noise: (equivalent sound pressure level; measured with true rms voltmeter); 23.5 dB typical, A-weighted; 25.5 dB typical, weighted per DIN 45 405
Dynamic Range: 117 dB (maximum SPL to A-weighted noise level)
Signal-to-Noise Ratio: 70.5 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
Power: Phantom Supply Requirement: 11 to 52 Vdc, positive at both pins 2 and 3; Current Drain: 1.0 to 1.2 mA
Connector: Three-pin (XLR) professional audio
Case: Aluminum construction with blue metallic finish, and hardened steel grille with nickel satin chrome plating
