Hello Fil
Yes, The BeoVision3 32" DOES have Masterlink as standard. I think that on some of the early 28" versions it was an optional extra. The 32" version is the same chassis as the Avant and ALL avants have Masterlink. The 28" BeoVision3 is the same chassis as Bcen1.
Of the current range of televisions, all have Masterlink EXCEPT BeoVision8. You have to order a "Sytem module" if you want to incorporate BeoVision8 into a link set up.
