Product Description

Shure Beta 91A

Condenser Boundary Microphone with Contour Switch for Miking Kick Drums and Low-frequency Instruments

Shure's outstanding Beta 91A half-cardioid condenser boundary microphone lets you capture a kick drum's true punch, without taking up a lot of real estate onstage. In fact, the Beta 91A excels at picking up all kinds of low-frequency-intensive instruments; its response is tailored for bass frequencies. The Beta 91A's integrated preamp makes it a very convenient condenser, and its ability to handle high SPLs means worry-free use in any environment (even with the loudest live drummers). A 2-position contour switch lets you choose between a flat response or a low-mid-scooped punchy response. You'll love what the Beta 91 does for your live sound!
