There are a few things that I can think of that may help. You haven't mentioned anything about speaker placement.How do you have them placed in your room? Are they placed on stands or on furniture/the floor? What is the size of your room? When you say you get no surround effects is this with certain movies or with all of them? If I'm not mistaken, your receiver is a 7.2 channel unit. Have you confirmed that your surrounds are connected to surround left and right rather than surround back? The Klipsch 500 is a 5.1 package, so if you are running 5.1 with the surrounds connected to surround back, you wouldn't get sound from the surrounds.Are you getting sound through the fronts, sub, and center appropriately? You may also want to research the YPAO setup and confirm that you are
doing the setup properly. I have a Pioneer with MCACC and after
researching a bit, I found that I'd missed a few steps. I'd also
recommend using a tripod to place the mic on during the setup. The mic
should be placed in the sitting position at about ear height. I'm new to this forum, but I've had experience setting things up and I've done quite a bit of research for my own system. I'd be happy to help however I can.
