Meets all the Needs
From Medium to Large Meetings
The Yealink CPE40, leveraging Yealink's advanced audio and AI algorithms, is a professional-grade omnidirectional microphone designed for video conferencing.It offers powerful sound pickup, lossless playback, noise cancellation, echo reduction, and full-duplex communication.
The device features three physical buttons—mute, volume up, and volume down—that sync with meeting software for easy control. The CPE40 should be paired with the Yealink CP50 for daisy-chaining, to meet the audio extension needs of medium to large conference rooms.
Crystal-Clear Natural Voice Reproduction
The CPE40 features an 8-element omnidirectional microphone array, supporting 360° audio pickup and a 6-meter range. Its high sensitivity and wide frequency response ensure superior audio capture. Equipped with high-quality full-range speakers, it reproduces natural voice, making video conferences immersive and allowing for clear, comfortable communication.
Intelligent Noise and Echo Cancellation
Full-Duplex Communication for Smooth Conversations
Utilizing Yealink's second-generation audio algorithms, the CPE40 automatically eliminates environmental noises, as well as echoes and reverberation from the meeting room. It supports full-duplex communication, providing clear audio pickup and output for seamless two-way conversations. The microphone also features automatic voice gain adjustment, ensuring that all voices are clearly heard regardless of volume.
Easy Deployment with 8-Device Daisy-Chaining
Focused Communication Without Constraints
Once connect to CP50, CPE40 can use a single POE network cable, up to 8 microphones can be daisy-chained*, to meet the audio pickup and amplification needs of small, medium, and large conference rooms while maintaining smooth and clear call quality. The POE cable simplifies deployment by eliminating complex wiring and keeping the meeting space neat and organized.
