Shure Beta 91A overview

  • 1Description

The Shure Beta 91A is a boundary microphone that can double as a kick drum mic, as it can capture the punch and attack of low-frequency instruments such as kick (bass) drums. It features a wide frequency response well suited for capturing a variety of audio signals such as organ and piano. The flat, boundary design also aides in producing a strong, solid low-end response, as well as make it easy to mount inside of a bass drum. The Beta 91A is ideal for both recording and sound reinforcement alike.

Uniform half-cardioid polar pattern for maximum gain-before-feedback and rejection of off-axis sound
Low-profile design features integrated preamplifier and XLR connector to facilitate 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
Furnished with zipper pouch

    Shure Beta 91A reviews

    Beta 91A Boundary Microphone is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from The best application for pianos Never could get a full rich natural sound until we installed this mic. It is used for live worship. Really allows for clear separation of tones without losing the natural sound of the piano.
