Audio Interfaces for TDM Systems
Table 4 lists the input and output capabilities of the various audio interfaces for Pro Tools TDM sys-
tems. In expanded Pro Tools|HD systems, audio interfaces can be combined for up to 96 audio inputs
and outputs (for example, with one HD Core card, two HD Accel or HD Process cards, and six I/Os).
In expanded Pro Tools|24 MIX systems, audio interfaces can be combined for up to 72 audio inputs
and outputs (for example, with one MIX Core card, five MIX Farm cards, and six ADAT Bridge I/Os).
