Professional lavalier microphone

The CK77 WR is an extremely small, omnidirectional professional lavalier microphone. The patented dual-diaphragm capsule has been designed to protect the transducer from moisture and perspiration.

The CK77 WR uses two vertical diaphragms mounted back to back to cancel out mechanical and cable noise by mixing the signals of both capsules out of phase. Its ruggedness and superior sound quality make it an excellent tool for theater and broadcast applications. The screw-on module capsule allows quick and easy service of the microphone.
