An Apple TV is often mounted into a Bang & Olufsen TV. Apple TV needs to have separate 230 volt power.

To make installation easier, BOSSCOM has made an adapter Y-cable so you can put a short Y-adapter into the extension of the supplied 230 volt cable which is included in the TV.
 
The solution is 2 female connectors instead of just one. This allows both Bang & Olufsen TV and Apple TV to be powered only with one cable instead of 2.
