Bob, I think my budget will allow this, so I've been doing my due diligence. Since the Behringer SCR2496 can send an AES/EBU signal out of any of the digital outs, wouldn't the best (and cheapest, of course) route be to send the AES/EBU signal out of the RCA digital out (75 ohms, and unbalanced--just what the ATEM calls for) via a RCA to BNC cable like this one?

Or am I missing some part of the equation?
