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).
The Beta 91A features a two-position contour switch to maximize attack and clarity depending on application: select the flat response setting for natural sound in most applications or the “low-mid scoop” setting for a strong low frequency “punch” with plenty of higher frequency attack.
Shure Beta 91A main features include:
- Uniform half-cardioid polar pattern for maximum gain-before-feedback and rejection of off-axis sound
- Precision-engineered low-profile design features integrated preamplifier and XLR connector to maximize setup efficiency while minimizing stage clutter
- Frequency response tailored for kick drum/low frequency applications with a wide dynamic range for use in high SPL environments
- Requires no external mounting or accessories for ease of use and storage
- Furnished with zipper pouch
- 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
