The Shure Beta 91A is a half-cardioid condenser boundary microphone designed specifically for kick drums and other low-frequency applications. It features a precision-engineered low-profile design with an integrated preamplifier and XLR connector, allowing for efficient setup and minimal stage clutter. The microphone is tailored to provide strong low-end response and maximum gain-before-feedback, making it suitable for high SPL environments.
The Shure Beta 91A utilises a uniform half-cardioid polar pattern to maximise gain-before-feedback and reject off-axis sound. Its frequency response is tailored for kick drum and low-frequency applications, offering a wide dynamic range that supports use in high sound pressure level (SPL) environments. The microphone is a condenser boundary type, providing a strong low-end response and superior attack and punch for studio-quality sound.
A two-position contour switch allows users to adjust the tonal character depending on the application. The flat response setting provides natural sound for most uses, while the ‘low-mid scoop’ setting delivers a strong low-frequency punch with increased higher-frequency attack. The device requires no external mounting and includes a storage bag in the box.
The Shure Beta 91A features an updated microphone capsule compared to the Beta 91, resulting in a more natural high-frequency response. While primarily suited for kick drums, it can also be used for other low-frequency sources such as pianos. It is distinct from the Beta 52A, which is a super-cardioid microphone offering even more low-end response.
