About the Yealink CM20 Ceiling Microphone
The CM20 is Yealink's beamforming ceiling microphone. Sixteen omnidirectional capsules form 8 pickup beams, covering about 30 m² at full-duplex quality and up to 60 m² in total, so the table stays clear of mics.
It powers over a single PoE cable, has a built-in DSP with echo cancellation, and supports AES67 for networked audio. The beam data can also drive camera speaker tracking on Yealink systems.
Use it with the MeetingBar A40, SmartVision 40 or MVC kits in medium and large rooms. Pair it with CS10 ceiling speakers, because a connected CM20 turns off the A40's built-in speaker.
Good to know
Can I use the A40's built-in speaker with a CM20?
No. When a CM20 is connected to the MeetingBar A40, the bar's built-in speaker is disabled; Yealink recommends pairing the CM20 with CS10 ceiling speakers.
Does it need an external DSP?
No. It has a built-in DSP with echo cancellation and works plug-and-play with Yealink MVC systems.
Can it go in a plenum ceiling?
Yes, it is plenum rated to UL 2043. A multi-ceiling mount kit (CM-MountKit) is sold separately.
