How Multilingual Interpretation Works? 1. The main speaker uses a TT117 transmitter to send the floor language on one channel, such as English on Channel 01. 2. Interpreters use TT118 receivers tuned to that channel to monitor the original speech in real time. 3. Each interpreter then uses a separate TT117 transmitter to broadcast their translated language on a different channel, such as Spanish on Channel 02 or French on Channel 03. 4. Listeners simply wear TT118 receivers and select the channel for the language they need. 5. Channel assignments are flexible, so you can set different languages to different channels according to your event requirements.
