Product Code: Beta 87A

The Shure Beta 87A is a premium quality supercardioid hand-held electret condenser vocal microphone with exceptionally smooth frequency response and high sound pressure level capability. Used for professional sound reinforcement, broadcasting, and studio recording applications, the Beta 87A combines superb performance with the ruggedness needed for touring and field production.

The Beta 87A features a controlled low-frequency roll-off that compensates for proximity effect and prevents the "boomy" sound often associated with close pick-up. The characteristic Shure presence rise brightens the upper midrange. The tight supercardioid pattern, with null points at approximately 125 degrees, provides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. The Beta 87A operates on phantom power.


  • 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
  • Minimally affected by varying load impedance
  • Very low susceptibility to RFI and electromagnetic hum
  • Advanced cartridge shockmount system absorbs mechanical shocks and reduces handling noise
  • Cartridge Type: Electret Condenser
  • Polar Pattern: Supercardioid
  • Frequency Response: 50 to 20,000 Hz
  • Sensitivity (at 1 kHz Open Circuit Voltage): -52.5 dBV/Pa (2 mV)
    1 Pa = 94 dB SPL
  • Output Impedance: 150 ohms
  • Maximum SPL ((1 kHz at 1% THD, 1k ohms load)): 140.5 dB
  • Signal-to-Noise Ratio ((referenced at 94 dB SPL at 1 kHz)): 70.5 dB
    S/N ratio is diff erence between 94 dB SPL and equivalent SPL of self noise, A-weighted
  • Dynamic Range (at 1 kHz, 1 k ohms load): 117 dB
  • Clipping Level (1 kHz at 0.25% THD, 1k ohms load): -6 dBV (0.5 V)
  • Self Noise (typical, equivalent SPL, A-weighted): 23.5 dB typical
  • Polarity: Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3
