Before I can understand what you want to do (and the setup in general) – and maybe make a suggestion – I’ll have to ask where your MCL2 devices are connected?
Normally the MCL bus is connected to an old audiomaster e.g. Beomaster 4500/6500….
The MCL2A does not need any power – it merely provides an extra set of speakers connected to the audiomaster with the option of muting/unmuting and controlling volume and changing sources of the audiomaster.
Only the 2AV version needs power (and active speakers connected).
It also has an option to act like a 2A (then without local sources).
