Good, they are all connected via ML.
TV: V.Option 2
BS9000: A.Option 0
On the BS5/BM5, there is an option to say that it is not an audio master (The BS9000 will be).
When using the remote the TV will send the Audio commands to the BS9000. For N.MUSIC and N.RADIO commands, the BS9000 will then call the BS5/BM5.
Options may vary if you decide to place these elements in different rooms.
This is not official from B&O but has been mentionned several times on this forum by some partcipants that are B&O dealers.
