Thank you for your quick response.
Are you sure the distortion caused by the card? I mean as the uTrack-X32 card has no DAC inside it takes the input digital signal then record in digital way it very unlikely is that distortion caused by the card. I don’t say it is not possible but very strange. We have never received any similar feedback from the users.
Do you you have enough headroom on the input gain of the console?
Could you please try to reproduce this if you have a really safe input headroom on each channels?
