So I'm selling one of these in the yard sale and I got a question from Dean as to whether it can accept an input and feed an output at the same time. I think the intention is to take an optical input from a ua-5 and send it to a D8, then pass it to a JB3. I never tried to do this, so I don't know if it can be done and haven't found anything about it when searching around. I'd try it out, but I only have one optical unit in my house, so I can't accept from that and pass to something else.
Does anyone have a definitive answer? Thanks!
