Description
The Shure Beta 91A is a premium boundary microphone designed specifically for kick drums, piano, and other low-frequency sound sources. Offering a blend of powerful attack and deep bass response, the Beta 91A delivers high-impact sound with studio-grade clarity—even at extremely high sound pressure levels.
Ideal for stage, studio, and broadcast use, this microphone provides engineers and performers with a reliable, low-profile solution for capturing every detail of low-end instruments. Available for hire in Melbourne, Sydney, and Brisbane, our Beta 91A mics are ready to elevate your sound on tour, in session, or at your next event.
Optimised for Bass Frequency Performance
The Beta 91A features a tailored frequency response that emphasizes the low-end punch and percussive attack essential in bass-heavy instruments. It captures frequencies from 20 Hz to 20 kHz with a smooth and powerful curve that enhances kick drums, floor toms, and grand piano soundboards.
With a full-bodied response and sharp transient detail, it allows sound engineers to achieve a tight, focused low-end without excessive EQ adjustments. Whether you’re looking to create a thumping kick in a rock mix or a smooth bass presence in a jazz ensemble, the Beta 91A is built to deliver.
Advanced Capsule and Integrated Preamplifier
The Beta 91A incorporates an updated electret condenser capsule with an integrated preamp and balanced XLR output. This design provides high output with low self-noise, making it ideal for both live and recording environments. The onboard preamp ensures a clean signal path, reducing the need for additional processing or gain stages.
Half-Cardioid Polar Pattern
The Beta 91A features a half-cardioid pickup pattern, designed to focus on sound sources directly above the mounting surface while minimizing background noise and bleed from other instruments. This makes it particularly effective for use inside a kick drum, where isolation from stage wash and cymbal spill is crucial.
Durable Low-Profile Design
Engineered for simplicity and durability, the Beta 91A’s flat, low-profile design allows it to be placed directly inside the kick drum without additional mounting hardware. Just position it on a folded towel or soft mat, and it’s ready to go. The metal housing is built for touring and live use, providing long-lasting reliability in demanding performance conditions.
