I have searched all the media and can find NO block diagram or explanation for this question. I will try and see if I can get clarification tomorrow when the gangs all here, but I would like to know why this is important? I mean it's pretty typical audio device configuration... I have to assume its got > Mic input >preamp> line input > preamp (buffer) then it usually branches out to the buss, and the feeds. Devices at this level don't offer the I/O for different devices like those costing many thousands more... but with features...
