Connections and Usage
Ceiling Microphone
PeopleLink CM is a high-per formance full-coverage pickup microphone developed by PeopleLink for classroom normalized recording & playback and remote interactive scenarios. A single PeopleLink CM has a pickup radius of 8 meters, and two CM’s can cover a classroom or conference room with an area of more than 120 square meters. Lecturers or conference speakers can speak anywhere within 2-8 meters from the omnidirectional microphone without affecting the pickup effect.
PeopleLink CM adopts large-size and professional-grade acoustic transducers to capture a wide dynamic range and can pick up a rich and full-bodied sound. The unique enclosure design effectively suppresses large space reverberation and can capture clear, undistorted, and omnidirectional sound.
PeopleLink CM is widely used in classrooms and conference rooms, and it is a model product of omnidirectional microphone in the industry.
