yealink CM20 – AI-Powered Beamforming Ceiling Microphone

Overview

The yealink CM20 is an enterprise-grade, low-profile ceiling microphone array engineered for high-fidelity audio capture in medium to large corporate conference rooms, executive boardrooms, and distance learning facilities. Designed to replace cluttered tabletop boundary microphones, this advanced ceiling endpoint solves the acoustic problems of multi-speaker overlap, ambient room echo, and uneven audio dropouts across expansive physical zones. The unit integrates natively with digital signal architectures to deliver clean, uncompromised full-duplex communication paths.

At the technical core of the hardware is a specialized 16-microphone omnidirectional matrix capable of executing 360-degree acoustic tracking. The internal firmware segments the room into 8 independent audio pickup zones, automatically identifying, isolating, and tracking active human speakers within a maximum radius of 4.5 meters (14.8 feet). Integrated AI-driven algorithms run real-time processing operations for Dynamic Noise Cancellation, Acoustic Echo Cancellation (AEC), and Reverberation Suppression, eliminating background HVAC or structural vibration rumble without clipping human speech parameters.

Deployment infrastructure is heavily streamlined by a built-in Digital Signal Processor (DSP), enabling direct plug-and-play functionality via standard network architecture. The device supports the AES67 protocol for straightforward interoperability with networked audio components and routes both administrative communication data and system power over a single Power over Ethernet connection. Designed to meet strict commercial architectural safety baselines, the chassis features a UL 2043 plenum rating for safe permanent installation inside building air handling spaces.

For physical deployment, the chassis features an ultra-flat 83mm profile that sits flush against tile drop systems or plasterboard finishes, enclosed by a detachable magnetic mesh grille. It can also be deployed via specialized pendant suspensions or surface-mounted ceiling brackets depending on structural height variations and aesthetic constraints. Do not deploy this endpoint in wet environments, outdoor locations, or spaces utilizing manual legacy analog mixing systems lacking PoE (IEEE 802.3af Class 3) infrastructure or compatible networked software switches.
