OVERVIEW

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.

Combines superior attack and punch for studio-quality sound.

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

    Comments about Shure Beta 91A Kick-Drum Mic:

    I'm very pleased with the sound quality of my base drum while using the Beta 91A. I get a nice tone with the punchy attack thats needed to help strengthen the grooves and drive of the band. Even when using a smaller PA system without subs, it preforms very well.

        Comments about Shure Beta 91A Kick-Drum Mic:

        This is for sure a must have mic for drummers. I have a beta 52, and the 91A is a nice addition because it really gives the punch of the kick.

            So much better than the "All Powerful" Subkick.

            Comments about Shure Beta 91A Kick-Drum Mic:

            One of the best purchases you could make to mic your drum kit, also would work great with a bass cab! You would just have to buy a special mount.
            Great look, built extremely well, only thing you have to watch is the thin cord that hooks up to the adapter.
            This is at a GREAT value if you want some extra punch to your bass drum, and it is $150 cheaper than the Yamaha Subkick, and it fits inside the bass drum easily ontop of a pillow so you don't have this weird looking drum,that is actually a microphonem outside of your bassdrum.

            Incredible Thump and Punch

            By 

            from Undisclosed

            Comments about Shure Beta 91A Kick-Drum Mic:

            This mic is truly amazing in a kick drum. It has great low end along with a clear, high, punch. I typically use it by itself, but I have paired it with a Beta 52, Audix D6, and AKG D112 and all the results where different, yet amazing. Try running your EQ flat with a 5k boost for nice punch and plenty of low-end. This mic is excellent and I highly suggest it.
