Hello gang, I finally have follow-up questions to the above. I sourced some 3-pin and 8-pin DIN plugs and a length of original MCL cable, and utilising this wet Sunday afternoon I have just about managed to solder all three plugs on to the cable. My soldering is pretty shocking but there seems to be connection between all the right pins. So, 8-pin plug into the BL3500 and the 3-pin plugs into the 3-pin MCL sockets on the BC9500, and I have sound! But... as soon as I plug the right 3-pin in, the sound from the powerlink-connected main speakers cuts out. I can control volume and source through the BL3500 with my Beolink 1000 remote, but the controls on the BC9500 appear to be disabled. It is as if the BL3500 over-rides the BC9500 completely. As an incidental if I plug some passive speakers into the speakerlink sockets on the BC9500 they work fine, and do not mute, but I still cannot control them directly via the Beocenter. Any ideas? Could it be a wiring problem with my hamfisted cable? Additionally I'd like to try the different L.Opt settings on the BL3500, but I can only find how to change them with a Beo4 remote. Does anyone know the right button sequence with a Beolink 1000? Thanks in advance,   Dave  

Hi again Regarding option settings, try that first. Reading your first post it sounds like the BL3500 is in another room than the BC9500, so opt. 6 would be right. Beolink 1000: Link + 6 + Store, the BL3500 should show option 6 in the display Regarding wirering the first thing I would check is if you are using the speaker 2 sockets for the MCL plugs, and that you have the correct left/right polarity (I do not suspect that as you can control the music)

Another thing that comes to mind that might not be a thing, but wont hurt to do is to check if Masterlink (ML) is set to off on the BL3500 as that is not needed in this setup. with the remote press Menu + 0 + 0 + Play ( If your BL1000 doesn’t have menu use shift + text). If the display show ML ON use the arrows to change it to ML OFF

Hi Mads,   Thanks very much for that, some useful things to try there. I'm away for a few days but will try when I get back. There was a cut-off ML plug in the back of the Beolab when I bought it so it may well be set to use the Masterlink at the moment, As you suspect the plan is for the BL3500 to go in a different room eventually so Opt 6 sounds right, but at the moment it is in my lounge attached to the BC9500 by a fairly short MCL cable.
