Yealink CM20 AI-powered beamforming ceiling microphone with 16 omnidirectional microphones, 360° coverage with 3.2m high-quality range (STIPA 0.78) and 4.5m effective range (STIPA 0.72), ideal for medium/large rooms

CM20 is designed for professional conferences, with 16 omnidirectional array microphones for 30㎡ full-duplex premium coverage (RT60=408ms@1kHz, noise 40dBA, height 2.8m), sensitivity 0 dBV/Pa, internal AEC channel, 8 beam outputs for accurate tracking. Removable mesh cover (Ø223 x H83 mm with cover, weight 615g, pearl light gray).
Supports Smart sound processing, camera integration, flexible ceiling mounting, 0-50°C environment, compatible with Teams/Zoom Rooms, Yealink Room Designer (Ø215×H81 mm without cover).
The Yealink CM20 introduces a paradigm shift in bringing professional ceiling microphone technology to a wider range of corporate meeting rooms. While ceiling solutions have traditionally been the preserve of large auditoriums with high costs and complex installation requiring specialized AV engineers, the CM20 breaks this barrier with an intelligent AI-driven design to simplify deployment and configuration while maintaining professional audio quality.
The microphone is based on AI-Powered Beamforming technology that adds an advanced AI layer on top of traditional beamforming technology. Not only does the CM20 create speaker-oriented pickup beams, AI algorithms continuously analyze the room’s acoustic environment and learn from its unique characteristics – including room dimensions, surface type, and recurring noise sources – to automatically improve pickup and isolation performance over time without any manual intervention.
The ceiling-mounted microphone is a slim, sleek design that seamlessly disappears into any modern office environment, freeing up the entire tabletop and giving participants a clean, comfortable space. The built-in microphone array with intelligent Beamforming packages covers the entire area of small and medium-sized rooms without any blind spots, automatically tracking the active speaker and enhancing their voice while filtering out ambient noise and echo.
The CM20 connects directly to Yealink conferencing and unified communications systems via a simplified connection, eliminating the need for a separate external DSP processor in many use cases – a strategic advantage that lowers the overall cost of the solution and significantly accelerates deployment. PoE (Power over Ethernet) operation is supported for a simple one-cable installation.
The microphone is managed via the Yealink Device Management platform with the ability to remotely adjust pickup settings and coverage areas, enabling IT teams to efficiently deploy and manage dozens of microphones across multiple locations from a single control panel.
