Hi Gady,

Welcome to Beoworld!  You do need an optical to co-axial audio converter like this one (as Stuart from B&O Ealing mentioned above):-

Do I order fro amazon the converter and still I can get the speakers to wake up but only one play I did all setup as advise 

Hi Gary, not sure if you got your problem fixed. You need power link mark II cable between the beolab 5 (the thick fully wired one). You can get it from steve.

Make sure you use fully wire power link mark II cable. You can get them from Steve, the best cable in the world.

Hi,

Thanks @alebouthillier, but the converter that is mentioned in the thread above is required, Beolab 5 won't work correctly with a Core unless the setup described above is used.  Fully wired Powerlink cables are also needed, I can supply these but I apologise that I don't stock the converters.

Kind regards, Steve.
