Hello. I'm new to setting up a surround sound experience. What exactly is dynamic range and speaker compression?? My Yamaha HTR-5740 receiver lets me choose a dynamic range setting. It has Max., Std. and Min. The default is Max. Can someone tell me exactly what happens if I switch from Max. to Std. or Min.? I understand some movies have a lot of dynamic range that will cause the volume and subwoofer responses to be greatly increased during certain scenes. If my receiver is set to Max. (compression), does that mean I am supposed to hear the full range of response? What would happen if I put it to Min.? I am a little confused because if Max. and Min. refer to "compression", what exactly is being compressed, and why would "maximum compression" give me the most dynamic range? Thanks for helping me understand these differences. I have searched the Web for information but nothing gives a layman's explanation of what this all means.
