Model ：TC-7108

Product Description:

The working theory of Infrared language distribution system is to use infrared transmission to distribute the language, with ultra confidentiality. It is the most advanced transmission style of infrared interpretation in the market. It is fit for small, medium and large size of meeting for requirement of confidentiality. The system can transmit max of twelve languages at the same time and the attendants only need to equipped with one small light transmitter to have the meeting content by choosing frequency.
