High-End Ceiling Microphone

The D7702 Ceiling Array Conference System is an innovative conferencing solution that simultaneously supports seamless on-site sound reinforcement, remote conferencing, and AI-powered meetings. It is designed to deliver clear, natural, and pleasant speech for a wide range of venues, including conference halls, meeting rooms, auditoriums, command and dispatch centers, lecture halls, and training centers. Built on an IP-based intelligent network architecture, the system is highly integrated, with all components powered by advanced AI voice processing and AI-powered seamless sound reinforcement technologies.

Unlike traditional public address systems, this system delivers an immersive and highly realistic audio experience. With ultra-low latency (<22ms), it ensures perfectly synchronized audio transmission, eliminating any perceptible delay that could distract participants. The system provides outstanding sound reinforcement gain (over 20 dB for local amplification), ensuring every word is heard clearly throughout the venue. Its microphone array captures sound from a distance with exceptional clarity, enabling highly detailed voice transmission both on-site and in remote meetings.

The D7702 Smart Conference System is designed for full-scenario adaptability. It easily accommodates a wide range of medium to large venues while effectively handling varying background noise conditions. With the ability to suppress and eliminate over 300 types of background noise, the system delivers rich, dynamic, and highly intelligible sound. With its full-bodied and natural sound reproduction, the system creates an experience as if the speaker were standing right beside you.
