    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 Condenser Microphone 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 with a wide dynamic range for use in high SPL environments
    • 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
    • Requires no external mounting or accessories for ease of use and storage
    • Furnished with zipper pouch

    Best Mic for internal Kick drum mic'ing

    I use Shure Beta 91A Mics in all of my Kick drums. Mounted with the Kelly Shu suspension system. This mic needs very little help in the way of EQ.

    Greatest mic for kick drum

    I know some people would like to do to use 2 mics in the drum kick, but I’m telling you if you only use this one, it’s more than enough
