Hi! new here...

i bought my self an behringer 8000mic+xenyx802 mixer/mic amp
now from what i read in the roomeq manual when doing the measure after soundcard cal.+ still in loop mode...it states:
"it should be flat to better than 0.1dB"
my isn't flat to 0.1dB.. mine is something like +/-0.1 to - 0.6dB over freq range?
i'm running the loop like:
behringer uca202 usb soundcard->mixer->uca202
why isn't it perfectly flat?...shouldn't rew calibrate it flat?
