I got back surgery. The MS-8 tells you to set the gains at the presumed 2v position. I think I might have misinterpreted that position because I misinterpreted my input range. I read a article from DD that said where 2v was but that article based off 6v max.
No DSP likes the be ran at full power, it will always introduce processor noise. I think I had to max mine out because I've been setting the amps 2v shy of the amps 2v position.
Basically I thought my amps where 6v so gains would be about 1/2 way. Well they are 8v. I still got a 1/4 turn to reach 2v. So I can add a good bit of gain and back the DSP off about 6db. That should lower the noise floor a lot and bring it just under audible.
All this is tricky with a stock HU. There is a fine line that has to be meet with DSP volume, HU volume, and gain.
I got a buddy coming by later to help me out. If this was my noise issue all this time I'm going to lose my **** mind.
I got the DSP backed off since you do it with the remote. It's good on CD but USB is not near as hot of a source. And I'm normally using USB. Typically playing a CD my master volume is about 6 clicks down from my USB volume.
