When I select a knob in any of the console emulations, and press "F1" I get all the info I need.
Which is where I got this:
Mode. Selects the desired console emulation mode. For each mode, the Console Emulator module closely resembles the hardware it is modeled after.
S-Type. Emulates a clean and transparent British console that is popular among mixing engineers in rock and pop genres. This console has potentially been used on more platinum selling albums than all other consoles combined.
N-Type. Emulates a British console that is used in legendary recording studios, including Abbey Road, The Village, Ocean Way, and Skywalker Sound. This console is warm and has a rich low end.
A-Type. Emulates a revolutionary British console, of which only 13 consoles were ever built. This console was made famous at Trident Studios and Cherokee Studios. This console has a brighter top and less lows than the N-Type console. Some consider this best sounding console of all time.
