The D7714 is a high-end ceiling array conference microphone featuring up to 104 high-performance digital microphones and hundreds of beamforming microphone arrays, delivering highly precise and crystal-clear voice pickup. Certified under the Tencent Tianlai technical standard and fully compatible with Tencent Meeting, the D7714 works within the Tencent ecosystem to create a consistent smart conferencing experience across various meeting scenarios. It supports one-touch functions such as joining Tencent Meetings, leaving meetings, and microphone mute control. Different Tencent Meeting statuses are intuitively indicated through LED lighting effects for easier and more convenient operation by users and participants.
It supports ultra-long-distance voice pickup and highly effective reverberation suppression. Equipped with advanced AI audio algorithms, the system can effectively eliminate more than 300 types of non-human noise and interference, creating a stable, quiet, and immersive conferencing environment.
The D7714 ceiling array conference microphone adopts low-latency IP digital audio technology, supporting PoE network power supply and IP cascading with up to 8 units. With its distributed cascading architecture, two or more ceiling microphones can be directly interconnected without requiring additional audio processors or mixers. This distributed solution offers greater cost efficiency, simplified deployment, and enhanced convenience. Using distributed voice pickup technology, the microphone maintains clear and natural speech reproduction whether operating as a single unit or in a multi-unit cascaded system, effectively avoiding hollow or muddy sound. In network transmission applications, it ensures stable audio transmission and broad compatibility. PoE technology further simplifies system cabling, while embedded, suspension cable, and suspension rod mounting options make it suitable for various high-end conference environments.
When multiple D7714 units are cascaded together, they automatically communicate and collaborate to accurately determine the speaker’s position. The optimal microphone beam is then intelligently directed toward the speaker for precise voice pickup, resulting in cleaner sound quality and extended pickup distance. This advanced distributed cascading technology enables multiple ceiling array microphones to function as one unified intelligent microphone system, delivering more accurate sound source localization, improved automation, and consistent voice pickup performance. Compared with conventional ceiling microphone solutions that rely on external mixers and audio processors for cascading, the D7714 provides clearer and more natural speech reproduction while effectively reducing reverberation and audio degradation in multi-microphone deployments.
The D7714 features highly adaptive AI noise reduction technology capable of suppressing more than 300 types of environmental noise. It effectively minimizes common background disturbances in conference rooms, classrooms, and factories, including air conditioning noise, fan noise, keyboard typing, table tapping, chair movement, touchscreen tapping, cup placement, and page turning. This ensures clean, comfortable, and distraction-free voice communication.
In addition, the D7714 includes an advanced AI Acoustic Fence function that allows users to define specific pickup zones while blocking sounds outside the designated area. Users can freely configure pickup regions according to different meeting spaces and scenarios. Four preset pickup modes are available and can be switched in real time via remote controller to quickly adapt to different applications within the same meeting room.
The D7714 ceiling array conference microphone integrates 104 high-performance microphones with an optimal voice pickup distance of up to 8 meters. It supports AI voice pickup, AI reverberation suppression, and full-duplex acoustic echo cancellation.
A single D7714 ceiling array microphone is ideal for medium-sized business and executive conference rooms, as well as classrooms. Through IP cascading technology, multiple D7714 units can be interconnected to accommodate larger application environments.
