Re: Expected signal voltage levels?(Long winded response) Hi Carl,     Thanks for the input. It helps a lot.     >You'll also want to have your equalization after   >all the preamp distortion.

Your gain calculations may be a litte off.   >You can't have gain at 0 Hz! Think about it for a   >few minutes.     The portion of the onboard preamp I was looking at(just a op-amp follower and a frequency dependant inverting op-amp) doesn't have a capacitor to block dc input. So I figured that if a dc signal came along it would be amplified. I now see however that there there is actually a capacitor in front of the onboard preamp and that no dc component would ever make it to the preamp section. Does this sound better?     Thanks again,   Peter
