The Shure BETA91A is designed for use with kick drums, as well as other traditional low-frequency applications including piano. Featuring an updated microphone capsule, integrated preamplifier, and XLR connection, Beta 91A offers a strong low-frequency response and is specifically tailored for bass frequency applications. The Beta 91A combines superior attack and punch for studio-quality sound, even at extremely high sound pressure levels (SPL).

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

What is the Beta 91A best suited to?

The primary use of the Beta 91A is kick drums. It can also be used for other low frequency applications including piano.

What are the characteristics of the Beta 91A?

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).

What is the difference between the Beta 91A and the Beta 91?

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.

Are there any other Shure Kick Drum microphones?

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.

Load Impedance:

Maximum SPL capability, output clipping level, and dynamic range vary with the input load impedance of the preamplifier to which you connect the microphone. Shure recommends a minimum input load impedance of 1000. Most modern microphone preamplifiers meet this requirement. Higher impedance results in better performance for these specifications.

Power Requirements:

This microphone requires phantom power and performs best with a 48 Vdc supply (IEC-61938). However, it will operate with slightly decreased headroom and sensitivity with supplies as low as 11 Vdc. Most modern mixers provide phantom power. You must use a balanced microphone cable: XLR-to-XLR or XLR-to-TRS.
