[quote user="richardjlarby"]I was just wondering if I could have my receivers set up so that one was powering hi end and the other low end. They are Sony STR-DB 930 and 940. Both have pre-outs and 5.1 ins.[/quote]
Sorry, my brain's still boggling at the question, but at least I've stopped staring at your post and muttering 'why???'.
Yes, I guess you could, if they both have similar output power, and at least one enables you to turn off all signal processing and get as near to a five-channel pass-through as possible.
Just remember that the one acting as a 'slave' - ie the one being fed via its inputs, and thus only acting as a power amp, should have all its speaker distances and levels set the same - and that means distances set to the smallest possible value - and all speakers set to large, with subwoofer output off, so that full-range audio is passed.
Let's put it this way: provided you wire it all up correctly you can't do any damage, and if it sounds horrid, as I suspect it may, what have you lost?
