General Description
The Set 830-TV is an infra-red stereo TV assistive listening system. The set enables assistive listening anywhere in the room without the need for cables and without disturbing others. Directly connectable to a TV, hi-fi system or radio, the Set 830 guarantees outstanding sound quality, which, for example, thanks to treble emphasis, can be customised to the listener’s hearing.
What’s more, the receiver is extremely lightweight and, with its perfect-fitting ear cushions, offers maximum comfort when worn. Ergonomic controls and visual signals for the individual control processes mean that operation of the Set 830-TV couldn’t be easier.
