You can use 4 in, 2 out 48khz 24 bit 2 in, 4 out 2 in, 2 out 94 khz 24 bit I think I am running up against this with my latest attempts. It may be that the quattro cannot do all 8 channels because of a hardware switch maybe for power consumption or something. They do run awfully hot and I can imagine that it would be possible to melt something if their is too much power running through them. -- Patrick Shirkey - Boost Hardware Ltd.
