I mostly watch movies. I have a projector w a full set of klipsch surround sound speakers: two towers, two rears surrounds, a center and a sub, but for some reason I seem to always end up setting the Yamaha receiver on 7 channel stereo instead of surround because it makes it so much louder in the rear speakers. I know this isn’t how it was recorded to be heard, and that surround separates everything but I just can’t hear it as well. Do I just need to turn it up more? I’m in an apartment so this is hard to do. What is the absolute best setting on the receiver for movies?
