Wrager, you might want to try this. I just received my Balanced MiniDSP and were in the same boat as you. I tried to run the MiniDSP with my system calibrated the way that it was but I was barely getting any sound out of my subs with the current setup. I have a Samson S-Convert that I was just using but wanted to eliminate anything I could in the chain so I decided to test out a theory that I had.
First, make sure that the jumpers are set to .9v. Mine came set to 2v on each input.
Second, I originally calibrated my system with my main levels at 0 and adjust my center and surrounds accordingly.
Here was my originaly level setting:
Mains: 0 dB
Center: -4 dB
Surrounds: -2.5 dB
Subwoofer: 0 dB (I previously didn't have a sub)
At these levels with my Onkyo Processor at -20 dB my speakers were very loud but the sub was nonexistant.
Third, lower all your speaker levels at the same rate EXCEPT
for the sub. You might need to bump the sub up a little bit if needed. I kept on adjusting it until it was how I wanted it. I adjust all my levels down -8 dB except for the sub which is now at +3 dB. I had my Crown XLS 2500 amp dial 2 notches from max (just under clipping).
Here is my new level settings:
Mains: -8 dB
Center: -12 dB (The lowest setting possible for me)
Surrounds: -10.5 dB
Subwoofer: +3 dB
Four, which these new settings the levels of all your speakers remain the same but you'll notice that at the same volume setting as before (-20 dB for me) it won't be nearly as loud and you'll have to crank the volume knob up however much you lowered your levels. Since I dialed everything down -8 dB I had to crank my volume to -12 dB to get the same volume as before out of my speakers but what this did was give my sub out signal more power which is what my amp needed to be driven to its max. With this method and just a +3 dB increase in the sub I was able to clip my Crown (with it dial at max) at loud action scenes! Of course I dialed the crown back a little bit to prevent it from clipping.
I don't know what youre settings are but if you're able to give what I did a try it might work out for you. My onkyo sub level can go up to +15 dB or something like that. I didn't want to push it that high so that I didn't clip the signal going out. I instead decided to try to lower all my other gains to compensate. I don't know if it's psychological or not but by doing this the sound comming out of my speakers seemed to be a little fuller and my surrounds seemed to be a little more noticable than before. Overall, I'm pleased with the test and will adjust some more when I get done with my dual ported 10's build as it's going to be a lot louder than my sealed 10's that I'm running now.
