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.

Features

• Cardioid polar pattern with tailored response for speech

• Dual-section gooseneck enables ease of positioning and placement op-

tions

• 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

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.
