CVB

Centraverse Boundary
Microphone

The Shure Centraverse CVB is a professional boundary
electret condenser microphone for use in desktop installed
sound reinforcement applications. Available in cardioid and
omnidirectional polar patterns and black or white color op­tions, its low-profile design fits seamlessly within any design
aesthetic.

Features

• Superior Shure design and rugged, dependable
construction

• Available in cardioid or omnidirectional polar patterns

• Attached 12 ft XLR cable

• Mounting holes for secure installation

• Commshield® technology guards against unwanted
RF interference from portable wireless devices
(smartphones, etc.)

Installation

1. Install two screws into the mounting surface, exactly 24 mm
(15/16 in.) apart. Leave a 5 mm (3/16 in.) gap between the
screw head and the mounting surface. Only use screws with
a flat-bottom head.

2. Place the microphone onto the screws and slide backwards
to lock into place.

3. Connect the XLR cable to a mixer or P.A. system.

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

Microphone Placement

Use the following information to achieve the best results for
each model variation.

① Cardioid

The cardioid model captures sound in front of the microphone
and rejects off-axis sounds. It is best suited to capture one
person or a small group in close proximity to one another.

② Omnidirectional

The omnidirectional model captures sound from all angles. It
is ideal for capturing larger groups and sounds coming from
multiple directions.

Model Variations

CVB-B/C: Black, Cardioid

CVB-B/O: Black, Omnidirectional

CVB-W/C: White, Cardioid

CVB-W/O: White, Omnidirectional

Note: Model availability depends on region. See your

local Shure dealer or distributor for details.
