MTG-100 Wireless Tour Guide & Language Interpretation System

MTG100 is a portable short-range wireless system used to transmit an audio message from a presenter to an audience. The presenter speaks into a radio microphone transmitter and the audience use lightweight receivers to hear the message.


The interpreter sits or stands on the periphery of the group, wears a battery-operated portable transmitter, listens to the proceedings and whispers the interpretation into a microphone (head-worn or lapel). This signal is transmitted to delegates who listen on wireless receivers within a range of about 100 m, depending on the model.

The receivers are multi-channel and each language requires a separate transmitter. Interpreters working together as a team for a single language must share a single transmitter and microphone.
