The Shure BETA 27 Instrument Microphone is a professional side-address supercardioid condenser microphone designed for demanding live sound reinforcement and studio recording applications. Built for engineers and musicians who require precise sound capture with excellent isolation, the BETA 27 delivers a natural, detailed response for instruments such as acoustic guitars, guitar cabinets, piano, percussion, brass, and other amplified sources. Its flat frequency response and low self-noise make it suitable for critical recording environments as well as high-performance stages.

Featuring a 1-inch externally biased ultra-thin 24-karat gold-layered Mylar® diaphragm, the BETA 27 provides fast transient response and accurate reproduction of complex musical details. The tight supercardioid polar pattern focuses on the intended sound source while reducing unwanted bleed from surrounding instruments, helping achieve higher gain-before-feedback in live applications.

The microphone includes integrated tone-shaping controls with a three-position low-frequency filter and a switchable -15 dB attenuator, allowing engineers to adapt the microphone for different sound sources and high-SPL environments. Its Class A, transformerless preamplifier design provides clean signal handling with minimal distortion, making it a versatile choice for both stage and studio use.

Designed with professional durability in mind, the BETA 27 features premium electronic components, gold-plated connectors, and a rugged construction suitable for touring and fixed installations. With its combination of clarity, isolation, and flexible control options, the Shure BETA 27 remains a reliable microphone solution for professional instrument recording and reinforcement.
