The core of TAIDEN infrared wireless conference system – dirATC (Digital Infrared Audio Transmitting and Control Technologies) - is a new technology originated by TAIDEN. It digitally encodes and modulates audio and data signals for transmission via infrared light, achieving both multi-channel audio signals and bidirectional data transmission and control. Digitalization combined with wireless transmission via infrared technology is an ideal solution for a wireless conference system. TAIDEN digital infrared wireless conference system is composed of a main unit, one or more transceivers and conference units.
