Description

Kick drum microphone provides a strong low-end response and maximum gain-before-feedback due to its half-cardioid polar pattern. It features a two-position contour switch to maximize attack and clarity and a low-profile design.

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).

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
Premier live performance microphone with Shure quality, ruggedness, and reliability
Uniform half-cardioid polar pattern (in the hemisphere above mounting surface) for maximum gain before feedback and rejection of off-axis sound
Tailored frequency response for kick drums and bass-heavy instruments
Wide dynamic range for use in high SPL environments
Two-position contour switch enhances attack and clarity
Integrated preamp and XLR connector reduce stage clutter and provide a quick, secure setup
Low profile design requires no external mounting hardware
Steel grille and die-cast metal construction resist wear and abuse
