3 Click the Main tab.
4 From the Clock Source pop-up menu, select
the appropriate clock source for the interface.
In many cases, you will use Internal. The other
choices are for resolving Pro Tools to external
clock sources. Depending on your audio inter-
face, Clock Source options can include: AES/EBU
[Encl], S/PDIF, Optical [Encl], AES/EBU 1–8, TDIF,
ADAT, and Word Clock (optional Word Clock
rates are available when operating at higher
sample rates).
5 If you want to send clock output to other de-
vices attached to the audio interface, select the
appropriate output from the Ext. Clock Output
pop-up menu.
6 Select which digital I/O port on your audio in-
terface enclosure is active by selecting the corre-
sponding option under Digital Format.
Depending on the type of interfaces in your sys-
tem, choices include AES/EBU, S/PDIF, and Opti-
cal (S/PDIF). Selecting Optical (S/PDIF) resets the
Optical I/O port (which is, by default, eight
channels of ADAT Optical I/O) to two channels
of S/PDIF Optical I/O.
7 For S/PDIF compatibility with Tascam DA-30
DAT recorders, select the Tascam option under
S/PDIF Format.
8 From the Input and Output channel pop-up
menus, select the physical ports (such as Analog
1–2 or Optical 1–2), that will be routed to the
corresponding Pro Tools input and output chan-
nels (such as Ch 1–2, Ch 3–4), listed on the left
side of the Main page.
Inputs and outputs of similar format are differ-
entiated in the input and output channel pop-
up menus. For example, the AES/EBU inputs and
outputs in the HD I/O enclosure are listed as
AES/EBU [Encl], while the AES/EBU inputs and
outputs on the factory-installed Digital I/O card
are listed (in pairs) as AES/EBU 1–2, AES/EBU
3–4, AES/EBU 5–6, and AES/EBU 7–8. For
HD I/Os equipped with a second Digital I/O
Card, the additional AES/EBU I/O ports on the
optional card are listed as AES/EBU 9–10,
AES/EBU 11–12, AES/EBU 13–14, and AES/EBU
15–16.
9 Configure any specific controls for your audio
interface:
• “Configuring HD OMNI Controls” on
page 75.
• “Configuring HD I/O Controls” on
page 76.
• “Configuring HD MADI Controls” on
page 77.
• “Configuring 192 I/O and 192 Digital I/O
Controls” on page 77.
• “Configuring 96 I/O Controls” on page 78.
• “Configuring 96i I/O Controls” on
page 79.
10 For additional Pro Tools|HD interfaces,
choose the interface in the Peripherals list, and
repeat the above steps.
Press Command+Left or Right Arrow keys
(Mac) or Control+Left or Right Arrow keys
(Windows) to move though the different
pages of the Hardware Setup.
See your peripheral’s guide for additional
configuration details and restrictions. For
example, the Optical 1–8 channels (on the
192 I/O enclosure) will not be available at
session sample rates of 88.2 kHz or higher,
while the ports on the 192 I/O Digital I/O
card will still be available.
