The Shure Beta 27 Supercardioid Microphone stands out as the only side-address, supercardioid condenser microphone designed for professional sound reinforcement. It features a switchable low-frequency filter and a 3-layer internal pop filter to reduce background noise.

The Shure Beta 27 Supercardioid Microphone is ideal for a wide variety of acoustic, wind and electric instruments, such as guitar and bass amplifiers, drum, percussion and piano. The tight supercardioid polar pattern ensures high gain-before-feedback and provides maximum isolation from other sound sources making it perfect for live stage applications. The Shure Beta 27 is tailored for superior transient response from a low-mass, externally-biased ultra-thin Mylar diaphragm. It has a flat, neutral frequency response for natural reproduction. The Shure Beta 27 uses premium electronic components and gold-plated internal and external connectors. It includes a 3-position switchable low-frequency filter which helps reduce unwanted background noise or counteract the proximity effect and the -15 db switchable attenuator handles extremely high SPLs with ease. The internal pop filter with three separate mesh layers reduces wind and breath noise.

    Solid build, flat frequency response

    I've been a fan of Shure's KSM LDC's for years, and I was curious to see how this LDC from their BETA line would work out. For acoustic instruments, it delivers a detailed, accurate representation of the instrument while adequately rejecting off-axis sound. Even the sources that bleed in the mic are relatively flat and can blend well with additional mics. I eventually plan to purchase a second BETA27.
