Professional Simultaneous Interpretation System for 3 Languages with Full Relay Capabilities

The Enersound TSP12-25 Professional System is designed to work when more than two target languages and full relay capabilities are needed.


The Enersound TSP12 Professional System is designed to work when more than two target languages and full relay capabilities are needed. This Professional Wireless Simultaneous Translation System provides superior sound quality and excellent coverage range, combining multiple-channel transmitter and receivers, as well as multichannel interpreter consoles with full relay capabilities. 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, console and headset per additional target language.

This system is equipped with the IC-12 Interpreter Console, a 12-channel dual interpreter console with full relay capabilities. Each console allows two interpreters to work together. Interpreters can choose either floor channel to listen to the speaker and perform direct interpretation or choose the relay mode (when the interpreter does not understand the floor language) and listen to the interpretation from a different booth in a language that this interpreter can understand. Unlike other interpreter consoles in the market, this relay mode is a true channel selectable relay function with audio level buster that allows the interpreter to select any of the 11 languages as their source language for the relay interpretation.

This system also incorporates the T-500 Transmitter, specially designed for language interpretation, with 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.

This system is ideal for multilingual conferences, meetings, court proceedings, and more, when two way interpretation is required.

This is system is sold in two different configurations: including 25 receivers or 50 receivers,

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