Normalized Recording and Broadcasting Classroom Terminal

The TCN107 smart education terminal features an upgraded high-performance processing chip that combines several functions into one intelligent device. It integrates a digital audio processor, video matrix, central control for teaching, media processing, video interaction, IoT management, automated recording and broadcasting capabilities, a POE switch, and other functional modules. The terminal is equipped with various input and output interfaces, including RS-232, RS-485, RELAY, I/O, infrared (I/R), USB, an amplifier terminal, MIC/LINE IN (with support for phantom power), LINE OUT with Phoenix connectors, HDMI, LAN, and WAN ports. This extensive array of connections allows it to interface seamlessly with different audio and video equipment, as well as environmental control systems, fulfilling the requirements for digitalized teaching in standardized recording and broadcasting classrooms.
