Chapter 4: Configuring Your Pro Tools System 47
6 Select which digital I/O port on your audio in-
terface enclosure is active by selecting an option
under Digital Format. Depending on the type of
interfaces in your system, choices include
AES/EBU, S/PDIF, and Optical (S/PDIF). Select-
ing 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. (The 96i I/O supports stereo
S/PDIF RCA digital input and output only.) For
more information about Pro Tools|HD enclo-
sure and card ports, refer to the guide for your
audio interface.
7 For S/PDIF compatibility with Tascam DA-30
DAT recorders, select the Tascam option under
S/PDIF Format.
8 For the 96 I/O and 96i I/O, click the Meters
pop-up menu and select whether to meter the
input or output signal.
9 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
channels (such as Ch 1–2, Ch 3–4), listed on the
left side of the Main page. (This feature is not
available with the 96i I/O.)
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 192 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
192 I/Os equipped with the optional 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.
10 Configure controls for your Pro Tools|HD au-
dio interface. See “Configuring 192 I/O and
192 Digital I/O Controls” on page 48, “Config-
uring 96 I/O Controls” on page 49, and “Con-
figuring 96i I/O Controls” on page 49.
11 For additional Pro Tools|HD interfaces,
choose the interface in the Peripherals list, and
repeat the above steps.
Refer to your peripheral’s guide for configu-
ration 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.
