Installed Sound Microphones
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.
