I have finally managed to scan the MCL2 System Manual! Some of it has been seen on Beotech before as I scanned the wiring diagrams ages ago, but it is all in one bit now. Looks in Service and User Manuals/Music Systems/Beolink Products/Master Control Link2 - MCL2. It is under System Manual. There are actually a little collection of manuals for MCL2 - should deal with most questions - though always happy to give a personal answer if necessary!

Thanks - I have been studying all these manuals with care, trying to figure out how to connect everything (multiple 2As and 2AVs!).

I note that this latest user manual talks about the early MCL2AV panel with an aerial cable.  Is there a later manual that includes the 2AV but without the aerial cable?

 

Probably! But these are dealer only manuals and I bought this one some time ago. It is actually an American one I believe.
