Follow up on this after more research.

From reading the H9000 with the Optional cards can act as a digital bridge between various digital protocols?

I have 2 independent sets of converters that ideally would pass signal digitally through the Eventide as a bridge.  I see optional cards are limited to 32 channels at 96k.  This would work for me.

Converter set 1:  Antelope Orion 4:  64 analog I/O to the console.  Will primarily use for D/A.  Thunderbolt to Mac Studio port connection.  Madi digital connection.  Orion can transmit both analog and digital simultaneously.  (Mac Studio).

Converter set 2:  IZ Radar Ultranquist:  16 I/O analog to the “print” mix tracks/rig.  Dante connection only.  (Mac Mini).

Is it possible to pass the converter digital signals back and forth through the H9000 bridge?
