Yealink CM20 – AI Beamforming Ceiling Microphone

Product Overview

The Yealink CM20 is an AI-powered beamforming ceiling microphone built for medium to large conference rooms that need clean, hands-free voice capture. Its 80mm low-profile housing and detachable magnetic cover (black or white) keep the ceiling line clean while supporting in-ceiling, on-ceiling, pole, and cable-suspension mounting. With a 16-microphone array, 8 independent pickup zones, and an integrated DSP, the CM20 connects directly to Yealink MVC room systems as a plug-and-play audio source. This makes it a practical pickup solution for AV integrators standardizing on Microsoft Teams Rooms hardware.

Product Description

The CM20 is engineered around a 16-unit omnidirectional microphone array that divides the room into 8 independent pickup zones, delivering even voice capture across the space rather than favoring participants closest to the table. It provides up to a 4m nominal coverage radius, with a 3m radius rated for premium full-duplex audio, covering roughly 30 square meters of effective pickup area. The EQ tuning is tailored to human vocals, so speech stays intelligible across the table.

AI Dynamic Noise Reduction and AI Reverberation Suppression run continuously, adapting to the acoustic conditions of each room to minimize background noise and echo. The CM20 also includes AI acoustic echo cancellation (AEC) for stable full-duplex calls. Because the DSP is built into the microphone, integrators can deploy the CM20 with Yealink MVC systems without adding an external audio processor, which simplifies the bill of materials and the rack. The magnetic snap-on cover speeds installation and service while preserving the integrity of the ceiling surface.

For buyers building out conference rooms, the CM20 pairs naturally with Yealink room kits and accessories. Browse the full range in our Yealink collection, and add the Yealink CTP25 touch console for in-room meeting control. The CM20 is a strong fit anywhere a clean ceiling-mounted microphone is preferred over tabletop units.
