High directivity and wide frequency response in a relatively short package make the C 568 B an ideal microphone for theater, sound reinforcement and film/video recording. Thanks to its compact size and light-weight design, the C 568 B is also ideal for camera mount applications. The C 568 B is an electret condenser design which operates on both pressure gradient and interference principles. Below 500 Hz it functions as a hypercardioid microphone; above 500 Hz, the acoustic interference tube increases its directivity for extremely accurate pickup of distant sound. A switch-selectable 12 dB-per-octave, 150 Hz roll-off filter effectively suppresses rumble and wind noise. The robust all-metal housing contains the built-in preamp and impedance converter and phantom power adaptor. The C 568 B comes with a foam windscreen and stand adaptor and does a beautiful job of capturing sound.
