Hello, I just bought this setup in the title. This is literally my first home theater set up. I bought the receiver for $75 and it works great so far, just no manual and no microphone. I really need help with setting up my system. I can figure how to make setting changes if necessary, but can you guys help me on what settings are recommended? Also, I don't understand the ratings on the receiver that well 20hz to 20khz at 90Watts and 1khz at 130 Watts? So far, I can only set up the 2 front speakers with the subwoofer, not enough space right now. Any suggestions would be really helpful. Thank you very much.
