Chapter 6: System Setup 73
For example, Pro Tools|HD systems can have
HD I/O, HD OMNI, HD MADI, 192 I/O,
192 Digital I/O, 96 I/O, or 96i I/O audio inter-
faces connected to Accel Core or HD Core and
HD Accel or HD Process cards in the system. The
HD I/O, HD OMNI, 192 I/O, 192 Digital I/O,
and 96 I/O can also have additional interfaces
attached using the Expansion port on each
interface.
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.
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. This illumi-
nates all the LEDs on the front panel of the se-
lected 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.
Configuring Pro Tools|HD Audio
Interfaces
HD OMNI supports up to eight channels of si-
multaneous I/O and multiple I/O formats (such
as analog, AES/EBU, ADAT Optical, and S/PDIF).
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 and multiple I/O formats
(such as analog, AES/EBU, ADAT Optical,
S/PDIF, and TDIF). HD MADI supports up to 64
channels of MADI I/O.
The Main page of the Hardware Setup 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 allows you to
route any of the inputs or outputs on your
Pro Tools|HD audio interfaces to channel as-
signments in the Pro Tools mixer.
Additional pages are available to configure other
controls for each audio interface (such as setting
operating levels).
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.
Use the Up and Down Arrow keys to scroll
though the Peripherals list in the Hardware
Setup.
