The Shure BETA®91A stands as the definitive microphone for capturing the full power and precision of kick drums and low-frequency instruments like piano. This specialised microphone features an updated capsule design with integrated preamplifier and XLR connection, engineered specifically to handle bass frequency applications with exceptional clarity and punch, even under extreme sound pressure levels.
Built with a uniform half-cardioid polar pattern, the BETA 91A maximises gain-before-feedback while effectively rejecting unwanted off-axis sound. Its precision-engineered low-profile design incorporates the preamplifier and XLR connector directly into the unit, streamlining your setup process and reducing stage clutter. The wide dynamic range makes it perfectly suited for high SPL environments where other microphones might struggle.
The microphone includes a two-position contour switch that allows you to tailor the sound to your specific application. Choose the flat response setting for natural reproduction in most situations, or engage the “low-mid scoop” setting to achieve that coveted low-frequency punch combined with crisp higher frequency attack. Requiring no external mounting hardware or accessories, the BETA 91A offers exceptional ease of use and storage, and comes complete with a protective zipper pouch.
