can I replace the MCL2A one at a time. for a MCL2AV on the same wire with active speakers. wil that room than be individualy from the others
That is a possible solution yes. The IR eyes are the same so you can replace wires 1 to 1. However the MCL2AV will need an external power adapter so you will need an outlet near the placement.
Beolab 3500 MK1 also has MCL integrated so also an option for individual volume control
The MCL2AV’s might not be that easy to find, so another option as suggested by Guy is to replace the MCL2A’s with Beolink passives (you allready have two and just need the newer IR eye) or Beolink Actives if you go for active speakers. Also the dedicated link room speakers Beolab 3500 and 2000 can be used here.
This will call for new cabeling for masterlink of course but you could do the conversion in sections
