    Stands high and dry

    for theater, house-of-worship and broadcast applications

    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.

    The CK77 WR L is available in three versions, differing in color and connector.

    Dual-diaphragm transducer
    for suppression of cable noise

    Resistant to moisture, perspiration and salt
    withstands sudorific stage performances

    Interchangeable capsule module
    for quick and easy service

    Omnidirectional polar pattern
    for unchanging sound quality in all direction
