Great to see you are still hanging around this old 950 forum Gonk. I'm sure you'll have an answer for this one, and i'm sure its been asked before !

I'm starting to hook up all my components again and i've come across a stumbling block. When i last had my system running, it was a 5.1 system. My new system is 7.1 and the 950's outputs in this regard are where my confusion starts.
I have always run the 950's amp outs through an ICBM before the amplifiers and there the issue starts.
The ICBM wants me to combine these inputs and outputs with extra Y adapters which will combine to give 2 mono signals (essentially 6.1).
So if the 950's rear surrounds outputs are discrete, i surely would not want to do this, right? Unless of course the 950 does NOT treat these discretely.
I'm thinking that although I've always left analog bass management off in the 950, and let the ICBM handle it, I may have to engage it and use it to control these two speakers.
