Shure Beta 91A Boundary Condenser Microphone

Useful in a variety of applications, the Beta 91A is a half-cardioid boundary mic that will give you a natural, ambient sound in the studio. It also makes a great kick drum mic in live applications.

The Beta 91A is optimised for kick drums, as well as traditional low end applications including piano. It uses a half-cardioid condenser boundary microphone with an integrated XLR preamplifier that is tailored for a strong low-end response. It has a two-position contour switch for optimised sound signature depending on application.


  • 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
