tion, then select the Legacy I/O (such as an
882|20 I/O), in the Peripherals list, and select No
Interface in the
Interface
pop-up menu. (The
96i I/O does not support Legacy I/O.)
6
Select which digital I/O port on your audio in-
terface enclosure is active under Digital Format.
Choices include: AES/EBU, S/PDIF, and Optical
(S/PDIF). Selecting Optical (S/PDIF) resets the
Optical I/O port (which is, by default, eight
channels of ADAT 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.)
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
pop-up menus, se-
lect the physical ports (such as Analog 1–2 or
Optical 1–2), that will be routed to the corre-
sponding Pro Tools input and output channels
(such as Ch 1–2 or 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.

Click other tabs (such as Analog In and Ana-
log Out) for additional configuration options
specific to the audio interface. These include:
• On the 96 I/O, configuring the operating
levels of analog inputs and outputs (+4 dBu
or –10 dBV).
• On the 96i I/O, configuring the operating
levels of analog inputs and outputs (+4 dBu
or –10 dBV).
• On the 192 I/O analog input, setting the in-
put connector and Soft Limit
• On the 192 I/O, configuring the two sets of
trims for analog inputs and outputs.
• On the 192 I/O and 192 Digital I/O, config-
uring real-time Sample Rate Conversion for
digital inputs.
• On the 192 I/O and 192 I/O Digital I/O,
configuring inputs and outputs on any op-
tional A/D card, D/A card, or Digital I/O
cards installed in the unit.
For more information about Pro Tools|HD
enclosure and card ports, refer to the guide
for your audio interface.
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.
For more information on Hardware Setup
controls for each Pro Tools|HD audio inter-
face, refer to the Pro Tools|HD Setup Guide or
the guide for that audio interface.
