After passing the test tone thru the mixer and recording the result in soundforge, i played it again to listen about the noise levels. At the silent passages (floor noise only) i run the statistics in soundforge, and these were the results:
Min sample value: -3 -80,77 db L & R
Max sample value: 2 -84,29 db L & R
RMS POWER: -90,36 db L , -90,23 db R
I know this is not a full compliant lab audio test, but may be useful to say if this unit is on the right track, regarding noise.
