Simultaneous interpreting host QT-TC701M

      The working principle of infrared language distribution system is to use infrared transmission for language distribution. It has strong confidentiality and is highly praised. It is an advanced transmission mode in the infrared simultaneous interpretation system on the market at present. It is suitable for all kinds of small, medium and large conference rooms and outdoor places with high confidentiality requirements. The system can modulate and transmit up to 12 languages at the same time. Participants only need to have a light receiver, and they can listen to the speech content by selecting the channel.
