Introduction Yealink CP50 is a professional-grade conference room speaker that integrates noise reduction, echo cancellation, and reverberation removal. It features Yealink's audio solutions and is equipped with an upgraded 8-unit omnidirectional microphone array for 360 ° pickup. It effectively eliminates conference room noises, including reverberation, echo, air conditioning vibration, and keyboard typing. Paired with high-quality full-frequency speakers, it delivers a clearer and more natural human voice. It supports daisy-chaining for expanded conference spaces and flexible deployment, ensuring stable calls and clear video conferences, providing an immersive audio communication experience. Key Features and Benefits High-quality sound, smooth callsEquipped with Yealink audio algorithms and an 8-unit omnidirectional microphone array, CP50 provides 360° sound pickup and effectively eliminates environmental noise. The high-quality full-frequency speakers make the sound clearer and more natural. Full-duplexFull-duplex allows for clear bidirectional communication, ensuring smooth and clear conversations during meetings. Multi-unit cascading for distributed scenariosUp to 8 devices can be cascaded via POE cable, meeting the pickup and amplification needs of different sizes of conference rooms, effectively avoiding sudden changes in sound volume and ensuring smooth communication (When cascading 4 or more CP50 devices with CPE40, it is necessary to choose the optional DC 48V/2A power adapter). Integrated meeting controlFeatures integrated mute, volume +, volume -, and Bluetooth physical buttons, synchronizing with meeting software status for easy control of the meeting. Multiple connectivity optionsUSB port for connecting to PC; internet port for connecting to video conferencing endpoint hosts; Bluetooth for connecting to mobile devices. Wired content sharing/BYODWhen used with MeetingEye 500 and other devices, it can directly connect to a PC via Type-C for instant content sharing. When used UVC85 and other devices, it can directly connect to a PC via Type-C for utilizing conference room audio-visual peripherals during computer-based meetings.
