Not an expert and not familiar with the LinkConverter ( yet ) but as far as i know almost all ML products can put sound on to the ML but only from one component at a time since there is only one "soundbus" on the ML. 

Only one unit is allowed to supply power to databus on the ML and sense is used to detect this.

Sorry but I do not understand your question, can you explain your setup (or future setup) a bit more.

 p.

The question is vil there be a conflict on the masterlink databus if both the TV (and link converter) and the Overture is on (see picture)

Wil there be a conflict when 

The TV/Linkconverter is trying to put TV sound on the Masterlink bus

The BS Overture trying to put audio sound on the Masterlink bus

Or can the conflict be handled by the BS ouverture and Linkconverter e.g by the Linkconverter will stop the sound from the TV when the Master put an audio sources on the masterlink bus ??????????????????

And you do not need a Beolink converter if your link room devices are Master Link compatible.

 Note that you will be able to listen to you TV from link rooms and from the main room, by pressing A.AUX. This will stop the CD or Radio in both cases.

 p.

The reason for the LinkConverter is easy use, almost B&O style friendliness (to a lower price).

Press <TV> and TV sound comes out of the speaker

Press <SAT> and the SAT sound comes out of the speakers

Press <DVD> and the DVD sound comes out of the speakers

Press <CD> and the CD sound comes out of the speakers

Try to tell my wife that she has to press A.AUX if she want to hear the television

So it make sense with the LinkConverter in the curent setup ! 

My question is can a LinkConverter and BS Ouverture control what is put on the MasterLink, or is a B&O TV needed for that ?
