In Emote, set CLOCK SOURCE to “Exp A (Dante)”.
Below, for Galaxy64, deselect “Enable Sync To External” and select “Preferred Leader”. For EVT-H9K, select “Enable Sync To External” and deselect “Preferred Leader”.
Check steps 4 and 5 on page 47 of the Galaxy manual, and repeat those steps for the EVT-H9K device: https://en.antelopeaudio.com/g64-sc-start/
These settings should sync the H9K to the Galaxy via Dante. Let me know how it goes.
