Connecting Audio Interfaces
Each Avid HD audio interface provides several
different input and output options. For
example, HD OMNI supplies up to 8 channels of
input and output to your Pro Tools system,
HD I/O supplies up to 16 channels of input and
output, and HD MADI provides up to 64
channels. Audio interfaces can be connected
directly to the HD Native card, or through the
Expansion ports on other HD audio interfaces.
The HD Native card supports up to 64 channels
of audio input and output. To get a full 64
channels of I/O, you can connect up to 4 HD I/O
to the HD Native card. Two of the interfaces
connect directly to DigiLink Mini Ports 1 and 2,
and the other 2 interfaces connect to the
Expansion ports on those audio interfaces.
You can also get a full 64 channels of I/O with
HD MADI connected to the HD Native card
using 2 DigiLink Mini cables. However,
HD MADI will be the only audio interface in the
system.
Refer to the HD OMNI Guide, HD I/O Guide, or
HD MADI Guide for specific details regarding:
• Front and back panel connectors and
indicators
• Installation of optional expansion I/O cards
(HD I/O only)

1 If you are using a single HD audio interface
(such as HD OMNI), connect the Primary Port to
