I don't know that there is a single point on a console that you could say that the console emulator exists at. Here's what I mean: When I mix through a console, I take my stems/tracks and go out of the Auroras into individual channels on a board. At that point there are any number of things that may happen: Trim, effect inserts, pan, and faders come to mind here, and then of course bussing and summing. So the console emulation could be said to occupy the same position as the signal coming into the mixer, and to emulate that you'd put it at the beginning. But it could also be said to be affecting signal that comes from effect loops, or after any gain happens, so to emulate that you'd put it after the insert effect or even post fader.
What that means is that in analog land, console emulation isn't a thing that take place in any particular point...or more accurately, it's many things that take place at lots of points.
