SKU: TSB Categories: ,

This Professional-grade Wireless Simultaneous Translation System provides superior sound quality and excellent coverage range, combining multiple-channel transmitter and receivers, as well as improved reliability and versatility. It can be expanded by adding an unlimited number of additional receivers. More foreign languages can be added for a maximum of 6 in the same room by purchasing 1 additional transmitter and microphone per language.

Specially designed for language interpretation, it has a unique integrated interpreter monitoring function. This feature allows interpreters to select an external incoming audio source and utilize a headset with microphone to listen to the source language without the need of an interpreter console or external headphone amplifier. Through the headphones’ volume control, interpreters can set the desired incoming audio level and the mute button allows them to momentarily silence their microphone for coughing or sneezing.  

The system is sold in different configuration to accommodate most needs. The bundles include options for 5, 10, 25, 50, 75 and 100 people. This is done by increasing the numbers of the included FM receivers.

This system is ideal for houses of worship, conference rooms, courtrooms, and auditoriums.

Note: This system requires a human language interpreter, it does not translate automatically.
