    Installation

    1. Drill a 22 mm (7/8 in.) hole in the mounting surface for the flange and three additional holes for the screws.
    2. Screw the flange into place, and then set the microphone into the center hole.
    3. Connect the microphone to a mixer or P.A. system using an XLR cable.

      Note: This microphone requires +48V phantom power to operate.

    Mute Button Operation

    Press the button on the microphone body to turn the mute on/off. The standard model does not feature a mute button.

    1. CVG12S: Mute is indicated by an LED on the microphone body:
      • Green = Microphone is on
      • Red = Microphone is muted
    2. CVG12RS: Mute is indicated by a light ring on the microphone head:
      • Red = Microphone is on
      • Off = Microphone is muted

    Guidelines For Use

    1. Maintain a distance of approximately 15 - 30 cm (6 - 12 in.) between the sound source and the microphone.
    2. Always use the supplied windscreen to control plosives and wind noise.
