I'm not sure if my Technics a-10 is hooked up properly into my Onkyo 787. I'm using optical connectors right now. I only get the front left and right channels to respond when I use the test section of the DVD-A demo disc even though I KNOW they're all working properly. Putting the receiver in surround puts sound to the rear channels, but it doesn't seem to be full-range sound. Do I need to use the pre-outs for each channel from my DVD player to the receiver?
