I've had my Elite 45tx for a few weeks now, and have been trying to read through the manual to get full benefit out of it, but I have one key question that I need some serious help with. If I only have a 5.1 surround setup, what should I use for the audio inputs (for SACD and DVD-A from a Elite 45A) - Surrounds L/R OR Rear Surround L/R. Same question goes for the speaker outputs for listening to multichannel audio and watching DVD's. I know that with a 7.1 system it is pretty self explanatory, but I'm a little confused here. My speakers are placed behind the main listening position a few feet on the sides. Any help would be greatly appreciated.
