The Shure Beta 91A is designed for use with kick drums, piano and other traditional low frequency applications.

For over two decades Beta Microphones have been the choice of top touring and recording professionals seeking reliable, application-specific performance in demanding live and studio environments.  With superior construction, low handling noise and high gain before feedback, Beta Microphones redefine sensitivity and control for expert sound reinforcement.  

The Beta 91A is a precision-engineered Half-Caridoid Condenser Boundary Microphone.  It's two position contour switch maximizes attack and clairty depending on the application.  This low-profile microphone with integrated XLR preamplifier is perfect for kick drum and other low frequency applications.  The Beta 91A requires no external mounting or accessories for improved control, simple set-up and storage.

An updated microphone capsule is tailored for bass-heavy environments to produce a powerful low frequency response, and a new design integrates the preamplifier and XLR connection for easy setup and minimal stage clutter. The Beta 91A combines superior attack and punch for studio-quality sound, even at extremely high sound pressure levels (SPLs).

  • Premier live performance microphone with Shure quality, ruggedness, and reliability
  • Uniform half-cardioid polar pattern (in the hemisphere above mounting surface) for maximum gain before feedback and rejection of off-axis sound
  • Tailored frequency response for kick drums and bass-heavy instruments
  • Wide dynamic range for use in high SPL environments
  • Two-position contour switch enhances attack and clarity
  • Integrated preamp and XLR connector reduce stage clutter and provide a quick, secure setup
  • Low profile design requires no external mounting hardware
  • Steel grille and die-cast metal construction resist wear and abuse

My favorite kick mic


I love the attack that this gives a kick. Mix it with a good sub kick mic, and you have gold!




A great low frequency mic!


This half cardioid condenser boundary mic will rock your kick. The beta 91a is specifically engineered for low frequency applications. With a built in mic pre-amp it really helps for low volume settings as well. This mic requires no external mounting and can just sit in a kick drum ready to roll. Also works well in some piano applications.

Great for Kick Drum


I use it in my kick drum when I need to be miked. The great thing is the punch I get from my kick drum. The convenience of not needing a small stand in front of my bass drum is another thing I like about it. It is a little pricey but worth the money.
