Yealink CMKit-121 ceiling audio kit
Overview

Yealink CMKit-121

The Yealink CMKit-121 is a complete ceiling audio kit for medium-to-large meeting rooms, bundling one CM20 AI beamforming ceiling microphone, two CS10 ceiling speakers and an RCH40 E2 PoE switch into a single deployable system rated for rooms up to roughly 5m x 8m, expandable to 6m x 10m by pairing two kits together.

The CM20 microphone uses a 16-element omnidirectional array split into 8 independent pickup zones, capturing speech up to 4 metres away (3 metres at full-duplex quality) through a built-in DSP that applies dynamic noise reduction and reverberation suppression without needing an external processor. Audio is reproduced through 2-way ceiling speakers tuned for speech and video conferencing, with Dante/AES67 network audio support and a PoE+ managed switch included.
