After updating to v1.3 and reading through this and a few other clocking-related threads, I think I finally have an aggregate audio device working between my UA Apollo TB2 stack and H9000R with USB + ADAT.

I wanted to confirm a setting for Mac OS X.

If I understand it correctly, the H9000 USB audio is clocked independently of the other digital audio. Is this true when synced over ADAT? I am currently clocking the H9000R via ADAT from an Apollo 8P while simultaneously using USB as an aggregate device. The setting I wanted to confirm is “Drift Correction“. Should this be enabled even if the H9000 is clocked over ADAT?

Here are my H9000R clock settings.

Everything sounds fine so far, but I thought I’d ask before I spend too much time testing further.
