The Beta 27 side-address condenser 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.
FEATURES:
•Supercardioid polar pattern specifically targets the sound source consistently with greatly minimized bleed from off-axis sound sources
•Tailored for superior transient response from a low-mass 1” externally-biased ultra-thin 24 Karat gold-layered Mylar® diaphragm
•Flat neutral frequency response for natural reproduction on stage or in the studio
•3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect for consistent extended lowend
•-15 dB switchable attenuator handles extremely high SPLs with ease
•Premium electronic components and gold-plated internal and external connectors
•Internal pop filter with three separate mesh layers reduces wind and breath noise.
SPECIFICATIONS
Beta 27 Side-Address Microphone
