It uses 16 omnidirectional microphone units across 8 independent pickup zones, with AI noise reduction and reverberation suppression, and an integrated DSP that works plug-and-play with Yealink MVC video systems. It runs on PoE over one RJ-45 cable and suits medium to large meeting rooms in Doha, Lusail and West Bay. Request a quote.

What the Yealink CM20 does in a meeting room

The Yealink CM20 is a ceiling-mounted microphone array built for conference rooms where people speak from several seats at once. Instead of a single capsule, it uses 16 omnidirectional microphone units arranged to cover 8 independent pickup zones, so a speaker at the far end of a table is captured as clearly as someone sitting beneath the unit.

Its beamforming design sets it apart from a standard ceiling mic. The CM20 provides 8 beam outputs for speaker tracking and integrates with room cameras for camera tracking, which helps when a meeting needs clear audio and a picture that follows whoever is talking.

Audio performance and the figures behind it

Coverage is quoted at two distances, each tied to a measured STIPA value. At 3.2 metres the CM20 reaches a STIPA of 0.78 for full-duplex capture, and at 4.5 metres the figure is 0.72. These results were recorded with an RT60 of 408 ms at 1 kHz, a noise level of 40 dBA and a deployment height of 2.8 metres, so use those conditions as your reference when comparing rooms.

Frequency response: 120 Hz to 16 kHz
Maximum SPL: 122 dBSPL
Signal-to-noise ratio: 86 dB at below 1% THD
Sensitivity: 0 dBV/Pa, 94 dBSPL at 1 kHz
Echo control: 1 internal AEC channel

AI Dynamic Noise Reduction and AI Reverberation Suppression adjust to changing room conditions, reducing background noise and echo before the sound reaches the far end. The EQ is tuned to bring out human voices.

Installation, power and network planning

The CM20 is powered over Ethernet under IEEE 802.3af, Class 3, through a single RJ-45 port, so one cable carries both power and audio. Typical consumption is 5.7 W and rated consumption is 9 W. It supports AES67 for integration into audio networks. Check that the PoE switch port meets the 802.3af standard and has enough power budget before installation.

It can be installed in-ceiling, pendant or on-ceiling. The body measures Φ223 × H83 mm with the mesh cover fitted and weighs 615 g. It is plenum rated to UL 2043 for air handling spaces. The package includes an assembly fixing bracket, bracing bridges, expansion bolts, self-tapping screws, machine screws and a dust cover, while a length-adjustable pole and suspend pole adapter are optional. A site survey helps confirm the ceiling type and the void before fixing.

Where the CM20 fits in Qatar

Ministry meeting rooms in Doha: internal reviews and calls with teams in other cities or abroad, where noise and echo reduction keeps remote participants clear.
Schools in Al Wakrah or Education City: staff training rooms and seminar spaces where teachers and presenters move around the room and need consistent pickup.
Corporate offices in Lusail or The Pearl: hybrid meetings that combine ceiling audio with a room camera that follows the active speaker.

What to plan before you order

Measure each room and record the ceiling height and the expected microphone height, since the performance figures assume 2.8 metres. Check the environment as well: the CM20 is rated for operation from 0 to 50 °C, storage from 0 to 70 °C and humidity from 5% to 90%. Summer temperatures in Qatar can exceed 45 °C, so confirm the ceiling void and room cooling with the SmartRooms Qatar team before installation. Multi-room projects can be quoted under a single purchase order.

Questions about CM20

What is the Yealink CM20 designed for?

The CM20 is a ceiling microphone for conference rooms that need reliable voice pickup across medium to large spaces. It offers a 3.2 metre pickup radius at a STIPA value of 0.78 and a 4.5 metre radius at 0.72, measured at a 2.8 metre deployment height. It suits a boardroom in West Bay or a government meeting room in Msheireb where several people speak from different seats.

How many microphones and pickup zones does the CM20 have?

The CM20 contains 16 omnidirectional microphone units that cover 8 independent pickup zones, and it provides 8 beam outputs for precise speaker tracking. Because the array sits in the ceiling, a person at the far end of a table is picked up without a microphone placed in front of them. This keeps the table clear for documents and laptops in a meeting room in Doha.

What coverage should I expect in my room?

Coverage is quoted at two distances. Full-duplex capture reaches 3.2 metres at STIPA 0.78, and 4.5 metres at STIPA 0.72. These figures were measured with an RT60 of 408 ms at 1 kHz, a noise level of 40 dBA and a 2.8 metre deployment height. Rooms with different acoustics will vary, so send your room dimensions and ceiling height with your quote request.

Does the CM20 need a separate DSP or audio processor?

No. The CM20 has an integrated DSP that works plug-and-play with Yealink MVC systems, so no external audio processor is needed when it is paired with a compatible MVC unit. It also includes AI Dynamic Noise Reduction and AI Reverberation Suppression that adjust to room conditions. Confirm compatibility with your specific MVC model using the manufacturer's device compatibility list, with help from the SmartRooms Qatar team.

How is the CM20 powered and connected?

The CM20 uses one RJ-45 port and draws power over Ethernet under IEEE 802.3af, Class 3, so a single cable carries power and audio. Typical consumption is 5.7 W and rated consumption is 9 W. It supports AES67 for integration into audio networks. Check that the PoE switch port budget and standard match these requirements, especially if the microphone shares a switch with cameras or other ceiling devices.

Can the CM20 be installed in a suspended ceiling?

Yes. The CM20 can be mounted in-ceiling, pendant or on-ceiling. Its body measures Φ223 × H83 mm with the mesh cover fitted and weighs 615 g. The package includes an assembly fixing bracket, bracing bridges, expansion bolts, self-tapping screws and a dust cover, and a length-adjustable pole is optional. A site survey helps confirm the ceiling type and the void before fixing, particularly in a school with suspended tile ceilings.

Is the CM20 suitable for ceiling voids that carry air handling?

The CM20 is plenum rated to UL 2043, which covers installation in air handling spaces. This matters in buildings where the ceiling void carries conditioned air, such as offices in Lusail or a hotel conference floor in The Pearl. Confirm the exact mounting method with the SmartRooms Qatar team before ordering so it matches the ceiling layout and the building services.

What temperature range can the CM20 operate in?

The CM20 is rated for operation from 0 to 50 °C and storage from 0 to 70 °C, with humidity from 5% to 90%. Summer temperatures in Qatar can exceed 45 °C, so the ceiling void and room cooling should be confirmed before installation, especially in a room with limited air conditioning. The SmartRooms Qatar team can help you check site conditions as part of your quotation.

Which colours are available for the CM20?

The CM20 body is Pearl Light Gray and comes with a removable magnetic mesh cover in white or black, so you can match the unit to the ceiling. The cover is detachable and easy to maintain. A white mesh suits a light ceiling in a government office or school, while black suits darker ceiling finishes. Mention your preferred cover colour in your quote request.

Will remote participants hear the room clearly during video calls?

The CM20 includes AI noise reduction and reverberation suppression, plus an integrated DSP tuned for human voices. These features reduce background noise and echo in the room before audio reaches the far end. This suits a Doha head office holding regular calls with teams in other countries, where unclear audio is a common complaint. Room acoustics still matter, so a site survey is worthwhile.

Can the CM20 work with a room camera?

Yes. The CM20 provides 8 beam outputs for speaker tracking and integrates with room cameras for camera tracking. This helps a lecture room in Education City or a training room in Al Sadd keep the speaker in frame during discussions. Confirm the exact camera model with the SmartRooms Qatar team, because camera compatibility depends on the room system you are building.

Can we order several CM20 units for a school or ministry project?

Yes. SmartRooms Qatar supplies the CM20 by quotation and accepts purchase orders (LPOs) and government tenders, including Monaqasat. Payment can be made by bank transfer, cheque or purchase order, and quotations are usually issued within one working day. Delivery covers all eight municipalities of Qatar, and a free site survey can confirm the ceiling layout for each room. The product is covered by the manufacturer's warranty.
