Description
The Shure Beta 91A 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).
Did You Know!…… that while boundary mics are widely utilized in conference rooms and training applications many Audio Engineers use them as drum recording mics. It’s true! Musicians and Audio Engineers can benefit from a pair of boundary mics by placing them on the floor on both sides of a kick drum, on the walls or even inside the kick drum. Have fun experimenting to find your killer drum sound.
Features:
- Uniform half-cardioid polar pattern for maximum gain-before-feedback and rejection of off-axis sound
- Precision-engineered low-profile design features integrated preamplifier and XLR connector to maximize setup efficiency while minimizing stage clutter
- Frequency response tailored for kick drum/low frequency applications with a wide dynamic range for use in high SPL environments

Really impressed overall. The Shure Beta 91A Half-Cardioid Condenser Kick Drum Microphone arrived quickly and works great. One star off because the setup was a bit complicated.

Not satisfied at all. The product failed to meet even basic expectations.

Recently bought this for about a month and this product does its job well. Minor issues don’t detract from the overall quality.

Using this for myself and would not recommend. Complete waste of money in my opinion. Had to return the Shure Beta 91A Half-Cardioid Condenser Kick Drum Microphone.
