You've been in enough Zoom calls where the person on the far side of the table sounds like they're speaking through a cardboard box. Everyone else hears you fine. That's the ceiling mic problem, and it's costing you credibility in every client meeting.
This kit kills that. One CM20 beamforming ceiling microphone locks onto active speakers and tracks them as they move. Two CS10 coaxial ceiling speakers push speech-tuned audio back across the room so nobody has to lean in. The RCH40 E2 switch (90 W PoE budget, four Gigabit ports) powers it all from a single run of cable.
You get install accessories for every component and two years of Yealink AMS support included. No separate service contract to chase down later.
If you're fitting out a boardroom or a 10-to-20-seat meeting space and want the audio sorted before the first call, this is the one box that does the job. Four units on the shelf in our warehouse now
