Configuring Audio Interfaces
HD I/O, 192 I/O, 192 Digital I/O, 96 I/O, and 96i
I/O audio interfaces support sixteen channels of
simultaneous I/O in multiple formats (such as
analog, AES/EBU, ADAT Optical, S/PDIF, and
TDIF). HD OMNI supports up to eight channels
of I/O in multiple formats. MADI I/O supports
up to 64 channels of I/O.
The Main page of the Hardware Setup dialog is
where you define which physical inputs and
outputs on your audio interface are routed to
available inputs and outputs in Pro Tools. You
can think of this window as a patchbay that al-
lows you to route any of the inputs or outputs
on your Pro Tools|HD audio interfaces to chan-
nel assignments in the Pro Tools mixer.
The Main page also provides controls for defin-
ing whether Expansion Port or Legacy Port pe-
ripherals are active (with 192 I/O, 192 Digital
I/O, or 96 I/O primary audio interfaces only).
Additional pages are available to configure other
controls for each audio interface (such as setting
operating levels).
Identifying Audio Interfaces
If you have multiple audio interfaces of the
same type connected to your system, before you
make audio connections to them, you should
confirm the identity of each interface. This en-
sures that you choose the appropriate interface
in the Peripherals list when you define its inputs
and outputs in the Hardware Setup dialog.
To identify audio interfaces in your system:
1 Choose Setup > Hardware.
2 From the Peripherals list, select an audio inter-
face connected to your system.
3 Make sure the Main page is shown.
4 Select the Identify option, located in the lower
left corner of the Hardware Setup dialog. This il-
luminates all the LEDs on the front panel of the
selected audio interface.
5 Make a note of which interface in your studio
setup corresponds to the identified interface.
6 Repeat the above steps for each additional au-
dio interface in your setup.
To configure Pro Tools|HD audio interfaces:
1 Choose Setup > Hardware.
2 From the Peripherals list, select the
Pro Tools|HD audio interface connected to the
first card in your system. This will be the inter-
face at the top of the list.

Legacy I/Os must be initialized in the Pe-
ripherals list before they can be identified.
See “Configuring Legacy I/Os” on page 59.
