Mixing OTB


boom box recordings
I have recently just started mixing otb. Is there a rule of thumb on setting the level before it goes out? Since I am using a Mackie VLZ Pro, I would like to think It would be better to keep the gain at unity on each channel on the board while maintaining a particular level through the RME converter.

I know that the final mix going back in should be around -12 digital db peaking.
