General Description

The Shure Centraverse CVG is a professional gooseneck electret condenser microphone for use in general installed sound reinforcement applications. With dual gooseneck sections for full articulation, the CVG12/18 provides scalable, best-in-class performance in a wide variety of locations, including podiums and desktops.


  • Cardioid polar pattern with tailored response for speech
  • Dual-section gooseneck enables ease of positioning and placement options
  • Three model variations with inline preamps: standard, mute switch, and light ring indicator
  • Available in 12” (30.4 cm) and 18” (45.7 cm) gooseneck lengths
  • Commshield® technology guards against unwanted RF interference from portable wireless devices (smartphones, etc.)
  • Included flange mount and snap-fit windscreen

  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.

[1]1 Pa=94 dB SPL

[2]THD of microphone preamplifier when applied input signal level is equivalent to cartridge output at specified SPL

[3]S/N ratio is the difference between 94 dB SPL and equivalent SPL of self-noise, A-weighted

[4]All specifications measured with a 48 Vdc phantom power supply. The microphone operates at lower voltages, but with slightly decreased headroom and sensitivity.
