My Equipment: - Marantz SR-7000 - Velodyne SPL-1200 - Sound Dynamics RTS-9's (mains)(dual 6.5's) - Sound Dynamics C2 (center)(dual 5.25's) - Paradigm Mini-Monitors (rears) Overally I have been having issues w/ the bass. Never seems quite right. Plus stereo vs DD was never the same. I set everything to small. Internall crossover is fixed at 80hz. I had the sub crossed over at 55hz or so and down. On the advice of someone here I turned off the sub crossover so it gets 80hz and down. My initial reaction is I like it and it sounds smoother overall. Upon doing this I noticed something really interesting. I have a channel level control for surround modes. So I can set the levels for 5-channel stereo independantly of say DD. Cool. So if go to TV which is set to 5-channel stereo I have: Main L: 0 Main R: 0 Center: -2 Sub: -8 Rear L: -6 Rear R: -6 When I go to DVD which is set to DD I have: Main L: 0 Main R: 0 Center: -1 Sub: -5 Rear L: -2 Rear R: -2 But my problem is that when I go to any 2-channel source (radio, cd, tape, etc ...) the channel levels it uses are from DD, so then the bass is rather over-powering. I would have thought 2-channel stereo would assume its own settings .... but just for Main L, Main R, and Sub. Is it just grabbing the mode of the video mode rather than the actual source selected. What I mean is I can watch a DVD source while listening to a CD. Is this affecting it? How then will I ever be able to set the sub level for stereo listening vs DD?
