Thanks MM,
The USB adapter is great for audio sources, but unfortunately Beomaster 5 cannot work directly with a non-B&O TV.
If you connect a TV to Beomaster 5 via the USB adapter, there will be a delay to the audio from the TV, so that it will not match the picture (this delay occurs within the Beomaster 5 and it is a known issue with B&O). The only solution to this is to buy a Beolink Converter from Bang & Olufsen (type 1161166) and connect this to the Beomaster 5 with a Masterlink cable:

In the BS5 menu, there is an “AudioMaster” submenu that needs to be selected as ON. There is also another menu just below it called “AM”, please set this to AM: 2 or AM: 6.
I can then help with a cable from the converter to the TV, depending on the audio outputs fitted to the TV.
Kind regards, Steve.
