Instrument 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 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.
