The scarlett 18i20 gen3 is a fantastic interface. The best way to connect your H9000 to it would be through ADAT, though this limits you to run sessions at no more than 48 kHz. You’ll get 8 channels of I/O with H9000 digitally. In addition, you could use the H9000’s analog I/O as additional inputs to your system by routing things internally using the Direct I/O patchbay capabilities of H9000, if you needed; it provides exceptional conversion.
