The manual on the Harman Kardon avr-525 has all the instructions for hooking up 5.1 & 7.1 speakers. However it doesn't say anything about 6.1 in the entire manual. Would I just hook up my center surround to one of the two rear surround terminals? And if I do would I be loosing any sound information that I would have gotten by using both speakers? Any help would be appreciated. Thank you guys in advance! I'm a bit new to HT, I had a sony HTIB that only had Prologic. I've broken down and have purchased a 6.1 Axiom speaker set up and a Harman Kardon AVR-525, I'll be using my onld sony DVD player along with a 61" (i think) Hitachi big screen (non-HD). I can't wait to get it all going!!!!
