Get to know them!

Thanks to its ultra-powerful low-end response, the Shure Beta 91A excels in every low-frequency situation. While kick drums are the obvious application, that’s not all this boundary condenser microphone can do. It’s also an effective way to capture pianos or any other bass-intensive source you can think of. Benefit from maximum gain before feedback, by virtue of a custom-tailored half-cardioid polar pattern, while impressive SPL handling effortlessly tackles extra-loud sources. A high-quality mic capsule design and integrated preamp yield superior attack and punch for studio-quality sound reproduction. The Beta 91A includes a 2-position contour switch to maximize clarity, as well as a low-profile design that enables it to fit anywhere.

Tailored frequency response offers high-quality low-frequency sound reproduction

The Beta 91A’s tailored frequency response makes it a top choice for loud, bass-heavy sources. Its uniform half-cardioid design all but rejects feedback, while supplying superior off-axis rejection. Its wide dynamic range ensures that it performs admirably in high-SPL environments. This boundary condenser mic has excelled in every situation we’ve encountered here at Sweetwater — kick drums and pianos in particular.

Intelligent design reduces stage clutter and resists abuse

Ask any live sound tech, and they’ll tell you — stage clutter is a serious thorn in their side. That’s one of the reasons why the Shure Beta 91A is a top choice amongst engineers. Its integrated preamp and XLR connector reduce stage clutter and ensure a quick, secure setup. Beyond that, its low-profile design requires no external mounting hardware and takes up little space. It’s also near bulletproof, thanks to its steel grille and die-cast metal construction.

2-position contour switch enhances clarity and attack

A 2-position contour switch on the bottom of the Beta 91A enables you to selectively filter its low-mid frequency response without necessitating any external gear. Set it for a flat response for natural-sounding audio reproduction, or flip it to the low-mid scoop setting for heightened attack and added low-frequency punch. This switch is perfect for situations where your signal needs a bit more clarity.
