I agree why the drawing board this is more a lab or brewery question.
I am trying to understand the question. But I will answer. There are various ways to tell if a console is analog(good) or digital(not like analog). It's simple. usually a digital console will have a smaller footprint, have one group of controls which would control the channel strip when accessed, processes all audio digitally I.E. gets converted on the way in and is a digital siginal till possiblely the way out, Has digital inputs and outputs, Usually will have a fairly small power supply which may or may not be external and lastly has switchable inputs I.E. MIc input one can show up on any channel without patch cable.. As for Analog, Well It processes audio in the analog world and will usually not convert it to a digital signal, Has Analog Connections, Has controls(EQ, Pre, etc, etc,etc) on each channel strip, Has set inputs that unlesses patched via patchbay will always be connected I.E. Mic input one will always show up on input channel one unless patched around, USually has external Power Supplies/supply, Has large Footprint,etc,etc,etc. You get the idea. SOme COnsoles are a hybreed console that is analog and digital LIke the Otari Concepts which is digital control of analog circuit so it looks analog and sounds analog but has digital control so routing(busses, auxes) is done in the master section and each channel must be access. Neevee did that with the horrible 8*1*0*8 series. Is there a reason you ask? Is there a board you are looking to buy?
