The user-installable expansion card allows Pro Tools HDX or HD Native users to connect the H9000 directly for up to 32 channels of direct I/O with Pro Tools|HD via its Primary DigiLink port. It can alternatively be daisy-chained with other Pro Tools interfaces via the Secondary DigiLink port with the included 12’ mini-Digilink cable. The H9000 can either sync to an external clock via loop sync/word clock, or the H9000 can be the clock source. Concurrent with the release of the Pro Tools|HD Expansion Card is the release of version 1.3 operating software for the H9000.
