George,

Thanks for the advise.
I went through all the connection again today(done that many times last night) and finally found out that the cable is plugged at the right place but on the 808.3 instead of the 861 v6, LOL.... amateurish mistake.

Robert,

Decided to take the ID40 at the 861 as well since in the future I may use the 808.3 in the living room while keeping the rest in a dedicated music/av room.

I still have problems with comm (not uniform response on L front and the other 4 speakers) and still having problem with getting RC completed as after L and R measurement, the center and the rears wont receive proper comm and remain at 50 db instead of 87 db like the LR. My DSP 8000 does not have SpeakerLink so I am using AC12 for LR with L speaker set as master. Connection is as exactly The AC12 manual. Going thru the AC12 blues thread now to try find the solution. will post there if can;t solve it.

808.3, Control 10/twinstore, OPPO BD 83, 621, 861 V6, DSP 8000, DSP 7200HC, DSP 7200
