Shure Beta 91A | Kick Drum Mic
$249.00
Half-Cardioid Condenser Kick Drum Mic with Integrated Preamp and XLR Connector
The Shure Beta 91A is a half-cardioid condenser microphone 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 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 zippered pouch
