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.
★ High confidentiality with function to avoid outer disturbing and bugging.
★ Fit for small, medium and large international meeting or outdoor activities.
★ ALC function.
★ Ultra ability to resist disturbing, disregarding to light and wireless communication equipment.
★ Simple connection to lower the project cost.
★ The most advance Phase-locked Loop technology.
★ Equipped with many channels of interpretation output for recording.
★ Equipped with many channels of audio input, max of four languages could be transmitting at the same time.
★ Input level indication.
