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.)
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.
Installation
- 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.
- Place the microphone onto the screws and slide backwards to lock into place.
- 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. |

[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.
