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).

A 2-position contour switch maximizes 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. Requires phantom power. Comes with zippered pouch.

  • 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
  • Wide dynamic range for use in high SPL environments
  • Two-position contour switch to maximize attack and clarity
  • 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

Cajon Mic


from Arizona

Comments about Shure Beta 91A Kick-Drum Mic:

I bought this mic in hopes to find an easy way to mic a Cajon. It works great, I mount it inside on the bottom of the Cajon with some Velcro. I had to use an XLR with a 90 degree bend so I could run the cord out the sound hole without kinking it. Now I don't have to mess with mics and stands behind me... The sound is amazing, picks up the highs and lows for the Cajon.
