Combines superior attack and punch for studio-quality sound.

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.

Shure Beta 91A Kick-Drum Mic Features:

  • 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

  • My first choice for Kick Drums

    As reviewed by Armond on 6/22/2011

    I am a Live Sound Engineer at a venue. I mix roughly 75 different bands a month. I purchased my Shure Beta 91a about a month ago and it quickly became my first choice for kick drums. It has a very full and tight low end. Low mid scoop (switchable) helps tremendously. Mic naturally has quite a bit of attack, only a little spicing up in the 3.15-4k and high shelf required if you desire an extremely clicky kick. Attack isn't at all obnoxious, works well with ANY genre. And that's by itself. Add a D6 or 52a and double your fun. With the integrated preamp you end up with a heavier mic, so it stays where you put it in non-permanent miking scenarios (not to mention no silly proprietary cable to mess with.) Shure really nailed it with this one. It's extremely well built, I'm sure it will last quite a long time. Size allows for it to fit in almost all kick drum holes (I haven't encountered one yet it didn't fit into.) If you are looking for the best kick drum sound possible (at this price point), look no further.

  • Cajon Mic

    As reviewed by KEVIN ENDRESEN on 3/14/2013

    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.
