Shure Beta 27 Condenser Microphone




zZounds Gear Experts Say...
Acoustically isolate drums, amp cabinets, and instruments with the Beta 27's tight supercardioid pattern. It's ideal for "live in the studio" recordings.
Overview
The Shure Beta 27 is a side-address condenser microphone that 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 insures high gain before feedback, and maximum isolation from other sound sources.
- Tailored for superior transient response from a low-mass, 1 inch 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 low-end
- -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.
