Half-Cardioid Condenser Boundary Microphone

The Shure Beta 91A is a half-cardioid condenser boundary microphone with an integrated XLR preamplifier that is tailored for a strong low-end response.  The Beta 91A optimised for kick drums, as well as traditional low end applications including piano. The Shure Beta 91A 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

Shure Beta 91A Features:

• 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
