Shure Beta 87A Handheld Vocal Microphone

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

N/A

Cartridge Type
Condenser (electret bias)
Frequency Response
50 to 20000 Hz
Polar Pattern
Supercardioid
Output Impedance
Rated at 150 ohms (100 ohms actual +/- 20%)
Recommended minimum load impedance: 800 ohms
Sensitivity (at 1000 Hz)
Open Circuit Voltage -52.5 dBV/Pa (2 mV)
(1 Pa = 94 dB SPL)
Clipping Level (at 1000 Hz)
1000 ohm Load: -6 dBV (0.5 V)
Maximum SPL (at 1000 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)
