Well, to save from double threads, I'll toss in my certified low end query; as I, too, find myself in a very similar situation. Working around an m/box, want
to put mic/di/trs/ts > pre > adc > m/box (via spidf), and I must get a copied audio signal to the analog input per "low latency monitoring". Yes, a dynamic, condensor, and ribbon mic will be involved. Obviously, prosumer town, thus, no tt patchbay involved. Suggestions?
