## Summary description

The Yealink CMKit-121 is a ceiling microphone designed for high-quality audio capture. It features an omnidirectional pickup pattern, a frequency range of 100 to 20000 Hz, and a sensitivity of 94 dB. The microphone connects via RJ-45 and is powered through PoE, making it ideal for conference rooms and professional audio setups.

## Long description

The Yealink CMKit-121 combines the CM20 ceiling microphone, two CS10 ceiling speakers and the RCH40 PoE+ switch into a single solution for medium to large conference rooms. The CM20 ceiling microphone uses a 16-element omnidirectional array and integrated DSP to capture clear 360° audio and works plug-and-play with Yealink MVC systems. The CS10 low-profile coaxial speakers deliver balanced audio for conferencing and support PoE installation with options for various ceiling types. The RCH40 E2 Gigabit PoE+ switch provides four Gigabit downlink ports and one Gigabit uplink, supporting 802.3af/at and up to 30 W per port with a total PoE budget of up to 90 W. The kit is supplied with installation accessories and includes a 2-year AMS service. Connection is via RJ-45 and the devices are intended for ceiling placement.
Advantages
The kit integrates ceiling microphone, speakers and PoE+ switching in a single package to simplify procurement and installation. The CM20's 16-omnidirectional microphone array and onboard DSP reduce the need for external audio processing while ensuring full-room coverage. CS10 speakers feature a discreet low-profile design that blends into modern meeting rooms while supporting PoE for simplified cabling. The RCH40 E2 switch supplies sufficient PoE power for the included devices and other room equipment, enabling a compact, networked AV setup.

Integrate the CM20 with Yealink MVC systems for plug-and-play audio processing; configure the RCH40 switch as required for VLANs or network quality-of-service if needed. Verify microphone pickup and speaker output, then adjust levels in the conferencing system or controller to obtain balanced audio for participants in the room.
Usage recommendations
For reliable voice pickup and even sound distribution, place the CM20 centrally or at evenly spaced positions depending on room shape, and mount CS10 speakers to avoid direct obstructions. Ensure the RCH40 E2 has adequate PoE budget for all connected devices and follow Yealink installation guides for optimal microphone array configuration and system firmware updates.
