Imported from Germany and can be used with all Bang & Olufsen speakers new & old. There is an RJ45 socket for connecting Loewe televisions with integrated DAL (Digital Audio Link) to the Digital Audio Link output of the TV. The RJ45 patch cable (CAT7) required for this can be bought anywhere for the required length. The unit is also compatible with sonos via the optical in. Full details from the manufacturer below

To connect Bang & Olufsen TVs, three RJ45 Powerlink sockets are available, one for the front speakers, one for the rear speakers and one for the center(R) / subwoofer(L). For newer TVs with RJ45 sockets you can use ordinary RJ45 patch cables (CAT7). For older TVs you need adapter cables (RJ45 Powerlink).

Comes in original box with UK power cable, Optical cable, instructions. Comes with UK figure of 8 plug to 3 pin plug but anyone in Europe can replace it to a Schuko terminator.
