Can someone advise me on a brand new HDX setup?

That only works for inserts. Not general input.

To correct delay on an input track (which only applies when delay comp is on), in the mix window, adjust the user offset delay. (in samples or milliseconds depending on what is selected in Preferences)

But a reminder, by default, when a track is input enabled or in record, delay compensation is disabled for that track until it is out of input enabled/record. You can put it in "blue mode" (Auto Low Latency off) to keep delay compensation active when in input enabled/record. (but of course, that means you will be hearing latency during recording)

(Also, a note from personal use: I usually just have the nudge value written and adjust after a pass vs using user offsets. User offsets fix the audio output but the clip/waveform will always look in the wrong place. Nudging fixes that. Otherwise you can end up in a situation where you are trying to align audio on two different tracks but it sounds off due to the user offset still being applied to one of those tracks)
