Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems AC12

I received my 861v6 upgrade this weekend along with 4 AC12 units for my DSP speakers and I will be posting about the 861 in another thread about my thoughts on a full M speaker setup with it by the end of the week.
I spent the weekend trying to get the comms to work and finally figured it all out (learned alot about comms along with it).
So as to try and save fellow HH'ers with a full nonspeakerlink DSP speaker system alot of frustration this is what I found in a system with no speakerlink speakers (not sure about a mixed system):
1) The master speaker(s) will work with an M lead comms cable and anything connected to it will also work (daisy chaining off of it).
2) A slave pair of speakers connected to the AC12 unit feeding an M lead cable will only work the first speaker it is connected to ( the second speaker connected by an S lead will not get comms). The reason is that the S connector on the M lead cable is different than one on an S lead cable-- it has one less wire lead soldered to it ( check the pictures on the wiki board) so it will not send a signal to the second speaker in the chain.
So the solutions are as follows:
1) Use a 511 slave patch ( best for me as all my cabling is in wall) and easy to implement.
2) Use an S lead cable and cut off one end and solder a phono jack and use a phono to BNC connector to connect to the master BNC on the AC12 ( I didn't try this but others have said it works).
3) Daisy chain comms around the room (not practical for me).
I hope this is helpful and saves hours of frustration for someone as the Manual doesn't show a full nonspeakerlink setup and seems to indicate that M leads will work - which they don't.
Anyway back to setting up the new 861 and enjoying the music.
Regards
Joe
