Thanks for the clearification - that explains a lot!
The Quantum-4848 is indeed an interesting device but would leed into the wrong direction (because it´s basically a computer audio interface which I exactly want to avoid).
"One last question":
Is there any difference between the Studiolive32SC and its predecessor Studiolive 16 regarding the maximum channels "at once". My question comes just because of the name "Studiolive16" to be honest ;-)
