HMM, what kind of outs does the ad-20 have? If it has both coax and optical, then yes. Otherwise, if it is just coax, a splitter should do the track. I plan on running mine with a splitter out of the mini-me like so:
split->nomad, split->m1.
Let me know and I will help you some more. And no, you are not a retard, just a person desiring to learn more!
