Yealink CM20 SkySound AI-Powered Beamforming Ceiling Microphone (1303095)
The CM20 is a beamforming ceiling microphone built for medium to large conference rooms, using an array of 16 omnidirectional microphones to capture full-duplex audio across 8 independent pickup zones. It delivers high-quality capture at up to a 3.2 m radius, with effective coverage extending to roughly 4.5 m depending on room acoustics, and its integrated DSP supports plug-and-play operation with Yealink MVC systems without needing a separate audio processor.
As a beamforming array, the CM20 tracks speakers through 8 beam outputs and can integrate with room cameras to enhance camera-based speaker tracking, adapting automatically to changing conditions through AI Dynamic Noise Reduction and AI Reverberation Suppression. It is PoE-enabled for single-cable installation and supports AES67 for integration into audio networks. Before ordering, confirm the room's ceiling type and plan the installation method (in-ceiling, pendant, or on-ceiling), since a separate CM20 Mount Kit is available for specific deployment methods, and confirm the network switch supplies PoE.

Certifications and Compatibility
- Yealink MVC systems: plug-and-play compatible, with the integrated DSP removing the need for external audio processing.
- Yealink 4th-gen MVC Series and all-in-one video conferencing devices: seamless integration per Yealink's published compatibility.
- Yealink SkySound audio solution: pairs with the CS10 ceiling speaker as a complete ceiling audio system.
- RCH40 E2: Yealink specifies the RCH40 E2 room cable hub (Energy Efficient Ethernet disabled) for CM20 connectivity, rather than the standard RCH40.
- Camera integration: beam-tracking data can enhance speaker tracking on compatible room cameras.
- AES67: supported for integration into broader audio networks.
- Compatibility is limited to Yealink-published systems. Confirm current compatibility against Yealink's device compatibility lists for your specific MVC system and firmware.
Design Considerations
- Confirm the room's ceiling type and choose the installation method (in-ceiling, pendant, or on-ceiling), using the separately available CM20 Mount Kit where the deployment calls for it.
- Confirm the network switch or hub supplies PoE, and specify the RCH40 E2 where Yealink's room cable hub is used.
- Plan microphone placement and coverage against the room's size, using the 3.2 m high-quality and roughly 4.5 m effective coverage radii as planning references.
- Coordinate with the CS10 ceiling speaker and connected room camera for a complete SkySound audio and tracking system.
- For multi-room standardization, specify a consistent CM20 configuration and mount method so every room's ceiling audio performs the same way.
Licensing, Warranty & Support
No license or subscription applies to the CM20. It is covered by a two-year hardware warranty, with terms available from Yealink or an authorized reseller at the time of purchase.
VideoConferenceGear.com Assistance
We can confirm the CM20 is the right ceiling microphone for your room size and Yealink MVC system, and help plan installation method and mount kit selection for your ceiling type. We can advise on coverage planning using the high-quality and effective pickup radii, coordinate the CM20 with a CS10 ceiling speaker and room camera for integrated speaker tracking, and confirm your network switch supplies the PoE the microphone requires. For multi-room and multi-site programs we can help standardize the ceiling audio configuration across every space.
Common Questions
