The D7712 Ceiling Array Microphone is certified to Tencent Tianlai technical standards and fully compatible with Tencent Meeting. Featuring a built-in Tencent Tianlai network protocol support and USB audio compatibility with Tencent Meeting audio processing, it delivers an exceptional conferencing audio experience. Through Tencent ecosystem integration, the D7712 enables a seamless and intelligent meeting experience across various application scenarios. It supports direct control of Tencent Meeting functions, including joining meetings, exiting meetings, and microphone mute control via physical buttons, while integrated lighting indicators clearly display different meeting statuses for more intuitive and convenient operation.
The D7712 supports IP audio technology, PoE power supply, and IP cascading with support for up to 8 units. Multiple ceiling microphones can be cascaded directly without requiring external mixers or audio processors, providing a more cost-effective, simplified, and convenient deployment solution.
Equipped with advanced distributed cascading technology, two or more D7712 ceiling microphones can work together through direct cascading without additional audio processors or mixers. When multiple D7712 units are deployed in a cascaded network, they automatically coordinate and collaborate to intelligently determine the speaker’s position, enabling the optimal microphone beam to precisely track and capture the speaker’s voice. This delivers clearer speech reproduction and extended voice pickup range. The distributed cascading architecture effectively combines multiple ceiling microphones into one larger intelligent array microphone system, delivering higher automation, more precise sound source localization, and superior voice clarity. Compared with conventional ceiling microphone solutions that rely on mixers and audio processors for mixer-based cascading, the D7712 avoids excessive reverberation and degraded audio quality commonly associated with large-scale system deployments. With distributed voice pickup technology, whether used individually or in cascaded deployment, the D7712 consistently maintains clear and natural voice reproduction while eliminating hollow or muddy sound.
The D7712 features highly adaptive intelligent noise reduction technology capable of suppressing over 300 types of environmental noise. It effectively removes various meeting, classroom, and factory noises such as air conditioning noise, fan noise, keyboard typing, desk tapping, chair movement, pen tapping, placing cups, and paper-turning sounds. This ensures clean and comfortable voice communication while minimizing distractions during meetings.
The D7712 ceiling array microphone integrates 20 built-in microphones with an optimal voice pickup distance of up to 8 meters. It supports AI-powered voice pickup, AI dereverberation, and full-duplex acoustic echo cancellation for enhanced speech intelligibility and conferencing performance.
A single D7712 ceiling array microphone is ideal for small and medium-sized business meeting rooms, executive conference rooms, and classrooms. Through IP cascading technology, the D7712 can be easily expanded for larger-scale applications.
