Bus Tour Guide (BTG). This system is dedicated to use in coaches, melexes and historic trams or trains. It works best as a multilingual tourist guide.

The receiver has built-in 2GB memory and can support multiple languages. Each language can have up to 999 audio files. Listeners can smoothly change the language by pressing a dedicated button.

The controller (transmitter) can control listeners' players. When the guide presses the button on the controller, the receivers will play back the relevant files in the language chosen by the listener.

The transmitter has the ability to connect a microphone, which allows you to send the voice of guide “live”, directly to the receivers when there are no previously prepared audio files.
