SPECS

The D74 Series Intelligent Digital Conference System is built on a professional ARM platform and integrates advanced DSP audio processing with high-fidelity circuit design. Offering high-quality audio transmission and reliable digital control, it provides an all-in-one solution for modern conference applications. The system includes the D74 Series Conference Host—comprising the digital conference system host and conference units—and supports features such as speech discussion, conference cascading, and seamless AI speech-to-text integration. With hand-in-hand connection via 8-core cables and cross-shaped adapters, the system ensures easy installation, stable performance, and strong anti-interference capability.

The conference unit serves as the essential device for participants to engage in and operate the conference. Conference units are the basic devices used by participants to attend and operate the conference. These units include chairman units, delegate units, and speech-only units. Different participants are assigned different types of units; for example, the chairman is equipped with a chairman unit that holds full control and operational authority over the conference order. All units are powered centrally by the control host and feature built-in speakers, headphone jacks, and LED indicators.

The conference units feature ultra-long pickup, high gain, intelligent noise reduction, and real-time feedback suppression for clear and natural sound. They adopt an electret cardioid condenser microphone with a red indicator light and include AI desktop chairman and delegate models with square or gooseneck microphone rods. Each unit has a unique ID that can be reset via the host, while the chairman unit supports request approval and priority control. Powered by the central controller with a 12V input, the units are easy to install, user-friendly, and designed with a sleek modern style.
