Hi guys. I have a soundcard M-Audio 1010LT. My mixer's output are at +4db. Should I put all inputs at +4dBu on my M-Audio Control Panel ? Also, any particular care for the inputs 1 and 2 on the 1010LT ? I know that these XLR inputs have preamps, so to my understanding they provide phantom power. It it safe to input directly from the mixer ? Thanks !
