A Hybrid Monitoring Feature There seems to be a lot of confusion over how you would incorporate a 3 way hybrid (recording, mixing and mastering (finishing) system with one converter You could I suppose but I don't. Specific for the (dangerous music summing) members wondering about those extra analog inputs on the ST or ( I'm guessing) AES inputs on the D-Box: I'm not certain with the D-Box (correct me if I'm wrong?), I don't use it but do use the ST. I hope this helps in respect to converters within your monitoring process. I use 3 independent converters ( AT THE SAME TIME) for these additional inputs because I don't necessarily want the same clock speeds (SR) (recording, mixing, mastering (finishing) within a hybrid system. Typical settings that may include one or all in your workflow: DAW 1< Multitrack tracking and mixing converter (32 channel ADDA) @ 88.2 or higher. Monitor via ST 1-4 analog switch. DAW 2 < The Mixdown DAW Stereo ADDA converter set @ 44.1 /24 . Monitor via ST 1-4 analog switch. The online monitoring DA is 44.1/ 16 Monitor via ST AUX switch. I use AES, FW and USB interfaces . What ever works for you is right. The Orion 32 > USB is a winner in this process. I switch between these all the time (recording, mixing, mastering (finishing) . Its part of the Dangerous Music workflow which has HUGE advantage with hybrid processing and monitoring. You can be tracking and mixing down at different SR at the same time. Analog in the middle going one way < DAW 2, makes this all possible. Monitoring all these areas can be done via a switch of a button.
