CK 77 WR

Common name: AKG CK 77 WR

Production Status: Discontinued / Vintage

The CK 77 WR (A version of the C 577 WR for use with wireless systems) is a professional miniature condenser clip-on microphone with an omnidirectional polar pattern. With its wide frequency range from 20 Hz to 20 kHz, low distortion at high sound pressure levels, small size, and versatile accessories, the microphone is an ideal choice for miking up musical instruments, lecturers, actors, preachers, etc. Other applications include TV and broadcast work as well as inconspicuous spot miking in live recording. The microphone features a dual-diaphragm transducer for efficient suppression of cable noise and mechanical noise that may occur when the microphone is used directly on an instrument. The two diaphragms are electrically connected out of phase. Impacts will move both diaphragms in the same direction so unwanted noise will be canceled out. Sound will move the diaphragms in opposite directions so the two output signals will add in phase.
