Chapter 2: Installing Pro Tools Hardware 17
Pro Tools|HD supports up to a maximum com-
bination of ten total of the following audio in-
terfaces:
• HD OMNI (only one HD OMNI is sup-
ported in a single Pro Tools|HD system)
•HD I/O
• HD MADI (up to three HD MADI can be
used simultaneously—requires six HD
cards)
• 192 I/O
• 192 Digital I/Os
•96I/Os
• 96i I/Os (up to five 96i I/Os can be used si-
multaneously)
For examples of connecting multiple I/Os, see
Figure 5 and Figure 6 on page 19.
To connect Pro Tools|HD audio interfaces:
1 Do one of the following depending on the au-
dio interface you are connecting:
• If you are using a single HD OMNI, HD I/O,
192I/O, 192DigitalI/O, 96I/O, or 96iI/O,
connect its Primary Port to the HD Core
card with the DigiLink cable provided with
the card (for HD OMNI and HD I/O you
must also use the included DigiLink to
DigiLink Mini adapter cable).
• If you are connecting HD MADI to your
system, connect HD MADI Primary Port 1
to the DigiLink Port on the first available
Pro Tools|HD card using the DigiLink cable
provided with the card and the DigiLink
Mini to DigiLink adapter cable included
with HD MADI. If you have a Pro Tools|HD
2 or greater system, connect HD MADI Pri-
mary Port 2 to the DigiLink Port on the
next available Pro Tools|HD card using the
DigiLink cable provided with the card and
the DigiLink Mini to DigiLink adapter ca-
ble included with HD MADI.
2 Connect additional Pro Tools|HD audio inter-
faces to subsequent Pro Tools|HD cards, or
daisy-chain the interfaces (by connecting the
Primary Port of the secondary interface to the
Expansion Port of the primary interface).
Pro Tools|HD audio interfaces need room at
their sides to maintain proper air flow for
cooling. Do not block the sides of the unit or
disconnect the internal fan. If the units are
rack-mounted in a case, remove the case
lids or doors before operating the system.
Failure to do so can result in the units over-
heating very quickly, which can perma-
nently damage sensitive components.
You must attach at least one HD OMNI,
HD I/O, 192 I/O, 192 Digital I/O, 96 I/O,
or 96i I/O to your system in order for
Pro Tools to launch.
Pro Tools HD supports only one HD OMNI
per system. If you are connecting HD OMNI
to your Pro Tools|HD system, it is generally
recommended that you connect it directly to
the Pro Tools|HD Core card.
