The AKG CK 63-ULS High Quality Hyper-Cardioid Microphone Capsule is designed for use with the AKG C 480 powering module. The capsule features a hyper-cardioid polar pattern, resulting in maximum pick up directly in front of the capsule, while providing adequate off-axis signal rejection. This results in high gain-before-feedback response and minimal noise due to ambiance. Wide frequency and sensitivity response ensures pristine audio reproduction. A maximum sound pressure level rating of 144dB enables the CK 63 to reproduce peaking audio levels without distortion and noise.
