PRODUCT DETAILS

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.
