I am running my FX III into a RME Fireface UFX II interface. I am wondering the best/cleanest connection option? I assume digital to digital would be best? The UFX II has ADAT/SPDIF optical and AES/EBU digital inputs. But the ADAT/SPDIF connector is not the RCA type found on the FX III SPDIF output so I assume it needs some kind of adapter. The simplest stereo connection looks to be via AES/EBU with a single AES/EBU 110 ohm XLR cable. Does that make sense and still provide stereo? Output from the UFX II is to my PC/DAW via USB and/or to FRFR monitors via the XLR 1&2 main outputs. Thanks for any suggestions.
