ROUTING ADAT SIGNALS

i had a few issues getting my mr816x to route into my project mix i/o controller/interface. This seems to be resolved now. i don’t know how i fixed it i think it was by reducing my buffer size in PT. my problem is this all the preamps seem to be connected to each adat channel. if i talk into a mic on any preamp then all the adat channels pick up a signal*. any one know haw to route to specific adat channels with the mr816x.

*the corresponding stereo channel doesn’t pick up any thing
ie
if im plugged into 8 there is no signal on 7
if im plugged into 7 there is no signal on 8

figured it out i just panned and muted. thanks any way.
