AKG CK31 Capsule
High-Performance Cardioid Condenser Microphone Capsule - DAM Series
The CK31 is a high-performance condenser microphone capsule with a wide cardioid polar pattern, especially designed for inexperienced speakers and applications where more than one person uses the microphone in turn. The CK31 capsule is integrated in a rugged metal housing and fits any mounting module of the DAM Series. To prevent contact problems, the capsule is equipped with large-area, self-cleaning, gold-plated contacts with deep threads to prevent misalignment and ensure extra-long life. The package includes a special two-part windscreen, which efficiently reduces wind and pop noise.
