Audio Interfaces for Pro Tools|HD Systems
Table 6 lists the input and output capabilities of the various audio interfaces for Pro Tools|HD sys-
tems.
You can expand your Pro Tools|HD system by adding Pro Tools|HD cards to your computer, either di-
rectly in the computer or using an expansion chassis. Expanding your Pro Tools system will provide
an increased track count, add to the amount of possible plug-in and mixer processing, and let you
connect additional audio interfaces. For more information, see the Expanded Systems Guide.
