Overview
The Yealink CP50 is a desktop omnidirectional microphone for video conferences, with an 8-element array that picks up voices across a 360° field over a 6 m range. It includes noise, echo and reverberation cancellation, full-duplex audio and a built-in 4W speaker. Up to eight units can be daisy-chained for larger rooms, making it a fit for Doha boardrooms, government offices and training rooms in Education City.
A desktop microphone and speaker for conference tables
The Yealink CP50 is a desktop unit that captures voices from around a meeting table and plays back the remote side of the call through a built-in speaker. Its 8-element microphone array provides 360° pickup with a listed range of 6 m, so participants do not have to sit close to a central device to be heard. At 151.8 × 151.8 × 75.3 mm, it takes up little table space.
Audio processing built for live calls
Yealink's second-generation audio algorithms remove environmental noise, echo and reverberation automatically. Full-duplex operation allows both sides of a call to speak at once, and automatic voice gain adjustment helps quieter speakers come through at a similar level to louder ones. The microphone has a listed frequency response of 100 Hz to 12 kHz and samples at 48 kHz with 16-bit depth. The speaker is rated at 4W, with a 100 Hz to 20 kHz frequency response and a 120° emission angle at 2 kHz.
Scaling up with daisy-chaining
- Standard adapter: the 48V 0.7A adapter supports up to three CPE40 units.
- Optional adapter: the 48V 2A adapter supports up to seven CPE40 units.
- Cabling: units are linked by Ethernet cable, and the package includes a 7.5 m cable.
Daisy-chaining relies on Yealink CPE40 units, which extend pickup and amplification across a larger room. A boardroom in West Bay might use one CP50 with the standard adapter and two CPE40 units to cover both sides of the table. A large training room in Lusail that needs more than three CPE40 units would call for the optional 2A adapter.
Connections and environmental limits
The CP50 links to a PC through its Type-C port, and its USB connection serves a computer or a conference display OPS. The current version supports Windows systems. A codec port connects to UVC cameras such as the UVC85 or to VC main units such as the MeetingEye 500. Bluetooth 5.0 pairs with mobile devices across a stated 10 m in an unobstructed environment, and physical buttons handle mute, volume up, volume down and Bluetooth.
Power comes from a DC 48V adapter, since PoE power and USB external power are not supported. Average consumption is 7.2W. The operating range is 0 to 40°C with 10 to 95% humidity, non-condensing. Outdoor summer heat in Qatar can exceed 45°C, so place the CP50 in an air-conditioned room and confirm the room temperature with the SmartRooms Qatar team before installation. Keep it away from windows that receive direct sun.

Questions about CP50
Who is the Yealink CP50 designed for?
The CP50 suits meeting rooms where one table of participants needs clear pickup on a video call, such as a boardroom, a training room or a small lecture space. It combines an 8-element microphone array with a built-in 4W speaker, so it handles capture and playback in one desktop unit. For larger rooms, several units can be chained together, which suits a government office in Doha or a company meeting room in West Bay that hosts calls with teams abroad.
How far can the CP50 pick up a voice?
The datasheet lists a 6 m pickup distance with 360° pickup from its 8-element array. Place the unit near the centre of the table so that seats at both ends fall well within that range. Automatic voice gain adjustment and noise, echo and reverberation cancellation help quieter participants at the far end remain audible. Before ordering for a long room, a free SmartRooms Qatar site survey can check the seating layout against the unit position.
How many units can be daisy-chained, and which power adapter is needed?
With the standard 48V 0.7A adapter, the CP50 can cascade up to three CPE40 units. With the optional 48V 2A adapter, it can cascade up to seven CPE40 units. The 2A adapter is an option and is not in the standard package, so specify it at quotation stage if a room needs more than three CPE40 units. Daisy-chaining depends on CPE40 units, so plan the count of those units along with the CP50 itself.
Does the CP50 power over PoE?
No. The datasheet lists PoE power and USB external power as not supported, so the CP50 runs from its DC 48V adapter. Average power consumption is 7.2W. The package includes a 7.5 m Ethernet cable for linking units and a 1.2 m dual-head USB-C cable for the computer connection. Plan a power socket near the table for the adapter before the unit is installed in a boardroom or training room.
Which computers and systems does the CP50 work with?
The CP50 connects to a PC through its Type-C port, and its USB connection serves a computer or a conference display OPS. The manufacturer notes that the current version supports Windows systems, so confirm the operating system of your meeting PCs before ordering. Bluetooth 5.0 connects the unit to mobile devices, with a stated range of 10 m in an unobstructed environment.
Can the CP50 be used with a UVC85 camera for a BYOD setup?
Yes. The datasheet describes pairing the CP50 with the UVC85 for a BYOD setup. A laptop connects to the CP50 by Type-C, and the UVC85 can project the computer's content to a monitor wirelessly. Yealink conference terminals can be added for wired screen projection. This suits a research group in Education City or a consultancy in Lusail that brings its own laptop into a room without a fixed AV system.
Does the CP50 work with the MeetingEye 500?
Yes. The codec port connects the CP50 to UVC cameras such as the UVC85 or to VC main units such as the MeetingEye 500. The datasheet also describes instant content sharing from a PC through Type-C when the CP50 is used with the MeetingEye 500. Confirm the full set of devices in your room before ordering, since the CP50 is the audio unit in that chain.
Can the CP50 run in a hot room in Doha during summer?
The operating temperature is 0 to 40°C, with humidity of 10 to 95% non-condensing. Outdoor summer temperatures in Qatar can exceed 45°C, so the CP50 should be used only in air-conditioned meeting rooms where the temperature stays within this range. Do not place it near windows that receive direct sun or in a glazed lobby. Confirm the room environment with the SmartRooms Qatar team before installation.
Where does a CP50 sit in a boardroom, and how are cables managed?
It is a desktop unit measuring 151.8 × 151.8 × 75.3 mm, so it sits on the table without a separate frame. The package includes a 7.5 m Ethernet cable, two cable ties, a cable cover and two screws. Route cables along the table edge and use the cover to keep the surface tidy. A SmartRooms Qatar site survey can confirm the cable path for a large boardroom before installation.
What does a training room in Education City need from the CP50?
Training rooms need pickup from a mixed group that moves between tables. The CP50's 360° array and 6 m range suit a seminar room with several rows of seats, and daisy-chaining can extend coverage when one unit is not enough. Count the CPE40 units first, then choose the 2A adapter if more than three units are needed. Request a quote with your room layout and seat count so the quotation matches the room.
Can a school in Qatar order several CP50 units on an LPO?
Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tender submissions, and payment can be made by bank transfer, cheque or purchase order. For a school fitting out several classrooms with the CP50, send the room list and seat counts so the quotation covers the CPE40 units and adapters each room needs. Quotations are usually issued within one working day.
