i just received some yamaha speakers for my birthday, last night i was hooking them up to my sony ns-de1075 receiver and i couldn't figure out if i should set it at 4ohms or 8ohms. the speakers claim an impedence of 6ohms. unfortunately sony's manual for the receiver appears to be written in a dialect similar to swahilli. who writes their manuels?? but i digress, what would you do in this situation?? from what i could deduce from the manuel setting the receiver to 4ohms seemed correct but i want to make sure before i forget about it and melt my receiver. any suggestions for a newbie?
