Sample toooo low

I know this question was already asked a few times but I didn't found the answer yet...so, when I sample (or resample the main out) in my 2500 the sample sounds waaaaay more quiet then the source, I mean my input signal is loud and clear, it's close to 0db sometimes even louder. Master level is set at -6 or 0 but the outcome is VERY low...I coulc normalize the samples but then the noise will become too loud! Any help? Thanks...

If master level is set to 0 in options and your sample is normalised the output should be sufficiently loud (probably too loud) when the master volume is maxed.
