Sorry for my noobishness, but I really have no idea what the hell ADAT is, and my MOTU 8pre has it/uses it. Normally I wouldn't care because I just use the 8Pre as a straight-up audio interface/preamp for mics when recording. BUT I just realized that if I want to get some better preamps (which I might), I obviously don't want the signal form the external pre to also go through the MOTU pre, which is what would happen if you just connected the analog output of the external pre to the input on the MOTU (I already checked - both the XLR and TRS inputs go through the preamp on the MOTU). I think the solution lies in something called ADAT, but I really have no idea what this means and all I know is that it has something to do with the fact that the MOTU can act as an "optical converter" (??). Please give me a nutshell explaination or direct me to some guide or something. I swear one of the most frustrating things in music is trying to figure out recording technology when all you know about it is what a mic is (that was me 2 years ago). It took me so long to even understand stuff like why mics need to go through preamps, what MIDI is, what a "condesner mic" is, etc. thank you!
