--------------------- Description ---------------------
The Shure Beta91 microphone is designed specifically for surface-mounted applications. It is a professional-quality permanently-biased condenser microphone with a half-cardioid directional pattern (cardioid in the hemi-sphere above the mounting surface.) Because of its half-cardioid polar pattern, the Beta91 surface-mounted microphone discriminates against sounds originating from the rear, suiting the Beta91 for conditions where an omnidirectional pattern makes other surface-mounted microphones impractical.
  
--------------------- Specifications ---------------------
 
Type:         Condenser (electret bias)
Frequency Response:         20 Hz to 20 kHz
Polar Pattern:         Half-cardioid (cardioid in hemisphere above mounting surface),
    uniform with frequency, symmetrical around axis
Impedance:         150 ohm (actual)
Sensitivity (at 1 kHz):         Open Circuit Voltage -59.0 dBV/Pa (1.1 mV); 1 Pascal = 94 dB SPL
Phasing:         Positive pressure on the diaphragm produces positive voltage on
    pin 2 with respect to pin 3
Connector:         TA3M 3-pin mini male XLR
Case:         Matte-black, painted, die-cast, zinc-alloy case with
    matte-black steel grille
Maximum SPL (at 1 kHz):         156 dB (20 Hz to 20 kHz, less than 1% THD)
Phantom Supply Requirement:         48 VDC +/- 4 VDC, positive pins 2 and 3
