I never touch that one (input gain). I always adjust my input gain on my audio interface. Isn’t that an option for you?
@Mizmiz This button is only used if your audio interface does not have an input gain control (as explained on page 2 of the MG2 built-in help, and as @LoFileiF says ).
Sorry, I think I got confused
The first day I used MG2, I did not try to understand anything and I put this knob almost to the maximum as well as the one of my audio interface since I had to have a good input signal… I had forgotten the proverb “Think before you leap”.
You, at least, are asking the question.
