The Shure Beta 91A is designed for use with kick drums, as well as other traditional low-frequency applications including piano. Featuring an updated microphone capsule, integrated preamplifier, and XLR connection, Beta 91A offers a strong low-frequency response and is specifically tailored for bass frequency applications. The Beta 91A combines superior attack and punch for studio-quality sound, even at extremely high sound pressure levels (SPL).

Shure Beta 91A Cardioid Condenser Kick Drum Microphone, Includes RPM626 Preamplifier.

Type: Electret Condenser
Frequency Response: 20 to 20,000 Hz
Polar Pattern: Half-cardioid (cardioid in hemisphere above mounting surface)
Impedance: 146 Ohms
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
Signal-to-Noise Ratio (referenced at 94 dB SPL at 1 kHz): 64 dB; S/N ratio is difference between 94 dB SPL and equivalent SPL of self noise, A-weighted
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 (20Hz-20 kHz at 1% THD): 1000 Ohm load: 7.50 dBV, 2500 Ohm load: 12.5 dBV; THD of microphone preamplifier when applied input signal is equivalent to cartridge output at specified SPL
Self Noise (typical, equivalent SPL, A-weighted): 29.5 dB SPL-A
Polarity: Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3
Weight: Net: 470 g (16.6 oz.)
Frequency Contour Switch: 7 dB of attenuation centered at 400 kHz
Connector: Three-pin professional audio (XLR), male, balanced
Power Requirements: 11-52 Vdc phantom power, 5.6 mA
