<b>Beta 91A Microphone</b>
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.
<b>WHAT IS THE BETA 91A BEST SUITED TO?</b>
The primary use of the Beta 91A is kick drums. It can also be used for other low frequency applications including piano.
<b>WHAT ARE THE CHARACTERISTICS OF THE BETA 91A?</b>
The Beta 91A is a half cardioid condenser boundary microphone. You can expect a strong low end response as it is specifically tailored for bass frequency applications, and superior attack and punch for studio quality sound even at extremely high sound pressure levels (SPL).
<b>WHAT IS THE DIFFERENCE BETWEEN THE BETA 91A AND THE BETA 91?</b>
The Beta 91A features a new and updated microphone capsule. The new capsule will result in a more natural high frequency response than the Beta 91.
<b>ARE THERE ANY OTHER SHURE KICK DRUM MICROPHONES?</b>
The Beta 52A is a super cardioid microphone and is also suited to kick drums. With the Beta 52A you can expect even more low end.
