The Shure Beta 91A is designed for use with bass drums, as well as other low-frequency instruments, including the piano. Featuring an upgraded microphone capsule, built-in preamplifier, and XLR connection, the Beta 91A offers strong low-frequency response and combines superior attack and punch for studio sound, even at extremely high sound pressure levels (SPLs).
Features:
Type: condenser
Frequency Response: 20 – 20,000 Hz
Polar Pattern: Semi-cardioid (cardioid in the hemisphere above the mounting surface)
Impedance: 146 Ohm
Sensitivity (at 1 kHz, open circuit voltage): – 48.5 dBV / Pa (3.8mV), 1 Pascal = 94 dB SPL
Maximum SPL (1 kHz at 1% THD): 1000 Ohm load => 151 dB, 2500 Ohm load => 155 dB
S/N ratio (referred to 94 dB SPL at 1 kHz): 64 dB
Dynamic range (at 1 kHz): 1000 Ohm load => 121.5 dB, 2500 Ohm load => 125.5 dB
Common Mode Rejection (20 Hz to 20 kHz): > 55 dB
Clipping Level (20 Hz-20 kHz at 1% THD): load of 1000 Ohm => 7.50 dBV, 2500 Ohm => 12.5 dBV, Self Noise (typical, A-weighted equivalent SPL): 29.5 dB SPL-A
Polarity: A positive pressure on the diaphragm produces a positive voltage on pin 2 with respect to pin 3
