+1 to Andy's comment this is NOT a good mixer, look into A+H ML or GL series, APB, Midas, or Soundcraft.
Heck, look for a used PM4000 before the m3000a. Unfortunately, there are not many mixers that are 56mono channels out of the box, if that is a requirement, then heavily consider and APB or A+H that make linking two desks together for channel count easily.
Personally, the no sound check really has no bearing on digital vs analog for me, heck that just makes me want a digital desk more, save the channel strip into a library and recall a channel where ever it needs to be loaded.
FASTER than analog by the second go round.
