Looking at the instruction manual
http://www.widex.co.u...200130%20001%2001.pdf
shows that the device takes its audio signal from the phono sockets on a TV. If there are no phono sockets, you need to use a Scart output and a Scart-to-phono lead.
The device has no way of knowing what it's attached to, so it will work just as well with any other input source (such a DVD player, BluRay player, etc) which also has phono sockets for the audio output, or which can be connected via a Scart-to-phono lead.
