I assume it has some in-built analog-style driveable stuff as it doesn’t clip? So in a sense it doesn’t matter about whether any channels except the master channel go over 0db then?
Also does it matter that my metering is set to +3db digital and yet my projects are set to +6db volume max (which is the minimum value?)
If I understand what you’re talking about correctly the number “+6” is the maximum amount of positive fader ‘travel’ above zero. So you can only increase the signal by 6dB using the fader. I believe the other number is +12, correct? So that’s all that that is. It really has nothing to do with metering.
