Yealink CM20, Beamforming Ceiling Mic, 16 MEMS Microphones, 30-360° Coverage, Dante & PoE, Compact 150mm.
The Yealink SkySound CM20 is a compact, in-ceiling beamforming microphone array featuring 16 omnidirectional MEMS microphones, 30° to 360° adjustable pickup coverage, and integrated AI noise reduction. Supporting both Dante network audio and native Yealink VCH protocol, it provides discreet, cable-free ceiling audio for medium-to-large meeting rooms.
Product Overview
With an ultra-compact 150mm circular architectural profile that blends seamlessly into any ceiling aesthetic, the CM20 captures voices naturally across a 3 to 5-meter radius. Its 16-element beamforming array actively tracks talkers while shielding the meeting from ambient HVAC hum and projector noise. The CM20 supports versatile deployment: it can operate as a native plug-and-play Yealink peripheral via CAT5e VCH port, or as a Dante audio endpoint on enterprise IP networks. Multiple CM20 units can be cascaded to cover elongated conference tables.
Why Buy This Product
Discreet Minimalist Profile
Compact circular form factor mounts flush into gypsum or acoustic ceilings, preserving clean room aesthetics.
Room-Wide 360° Tracking
16 beamforming microphones track active voices across 30 to 40 square meters without blind spots or dropouts.
Onboard AI Noise Filtering
Internal DSP suppresses air conditioning noise, keyboard clicking, and room echo before audio reaches the conference call.
Single-Cable PoE Efficiency
Transmits high-definition digital audio and draws operating power over a single standard Cat5e/Cat6 network cable.
