So is the H9000 MADi config set to “Auto/64” or “64”?
I’ve just set it to “64 ch”. I assume “Auto/64” would work just as well.
I’ve only ever encountered clocking problems with wrongly set up clocking. I know that ADAT doesn’t carry the info about wether or not the signal is S/MUXed or not. So switching between 44,1/48kHz and multiplexed/ higher sample rates might offset your clocked devices. (in ADAT, 96kHz is achieved by combining two 48kHz channels, so the incoming signal is still 48kHz etc.) I don’t know about the Apollo, but you may have to manually enable the S/MUX mode for the incoming signal?
