This is not possible for the following reason: the Digital Card on the 192 I/O can sample rate convert on input (AES, TDIF, or ADAT on the digital card), but cannot sample rate convert on output (AES, TDIF, or ADAT).As a workaround, you can go analog out to the effects processor, and return digitally from the effects processor (or just use analog in and out to the effects processor).
