I got a cheap subwoofer for XMAS ... what "gain" should I set it at? I could tell it would get louder the more I turned it up. Am I looking for a blend with the other speakers? Another thing ... is there any way to get the middle channel (dialouge) to be louder in comparison to the rest of the soundtrack? When I watch action movies, I'm constantly turning the volume up during "talking" scenes and down during action scenes. I have a Denon AVR1602 receiver. Couldn't find anything in the manual. Seems like on my old receiver you could set the volume of the middle (or rears) in relationship to the mains. Any suggestions?
