Function Extension Box


In 2015, TAIDEN introduced its worldwide pioneering digital infrared technology into the field of multimedia teaching and released the world’s first digital infrared wireless classroom audio system. The system provides an ideal solution for teaching environment owing to its various advanced features such as great immunity to interferences, reliable privacy assurance, convenient management and excellent audio clarity.

Not stopping there, TAIDEN developed Interactive Recording and Webcasting Audio System dedicated to recording teacher’s instruction and students’ interaction in class by integrating digital infrared technology, DSP technology with array microphone. The system ensures broadcast level audio quality by picking up teachers’ sound with IR microphone, and the sound can be separately routed to the classroom reinforcement system. A 360-degree array microphone is used to pick up students’ interactive activities; the sound will be further processed by the “3A” algorithm (ANC, AEC, AGC) and then mixed with the teacher’s audio to be fed into a third-party recording system. The Interactive Recording and Webcasting Audio System makes a perfect audio solution for class recording and reinforcement by offering crystal-clear reproduction class activities and facilitating automatic video tracking.
