It is now 10pm. I have been on since 6pm trying to get this reciever to setup. My problem appears to be my rear speakers. A very silly question.. Do I connect them on the reciever to Surround Speakers OR Surround Back speakers? This is doing my head in as I have little space to work in. Also as my rears are 4 ohms and the rest is 8 ohms would this be why I get an error reading?
