The Shure Beta 27 side-address condenser instrument microphone is precision engineered for professional sound reinforcement and project studio recording applications. Its flat frequency response and low self-noise provide unerring performance in demanding environments. A tight supercardioid pattern ensures high gain-before-feedback and maximum isolation from other sound sources.Shure Beta 27 Features:Supercardioid polar pattern specifically targets the sound source consistently with greatly minimized bleed from off-axis sound sourcesTailored for superior transient response from a low-mass, 1 externally-biased, ultra-thin 24 Karat gold-layered Mylar diaphragmFlat, neutral frequency response for natural reproduction on stage or in the studio3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect for consistent, extended low end-15 dB switchable attenuator handles extremely high SPLs with easePremium electronic components and gold-plated internal and external connectorsInternal pop filter with three separate mesh layers reduces wind and breath noise
