HD Native Installation Guide14
Maximum I/O Configuration
HD Native supports up to a maximum
combination of up to four total of the following
audio interfaces:
• HD OMNI (only one HD OMNI is supported
in a single HD Native system)
• HD I/O (up to four HD I/O can be used
simultaneously)
• HD MADI (full connectivity with one
HD MADI is possible when both DigiLink
Mini ports of the HD MADI are connected
to both DigiLink Mini ports on the HD
Native card)
For an example of connecting multiple Avid HD
audio interfaces, see Figure on page 13.
Installing and Authorizing
Pro Tools Software
Once you have installed your HD Native
hardware in your computer, you can install and
authorize your Pro Tools or Pro Tools HD
software (sold separately).
Installing HD Native
Hardware Drivers
HD Native hardware drivers are required for
your HD Native system to support digital audio
software, such as Pro Tools, and Core Audio
(Mac) or ASIO (Windows) compatible digital
audio software (such as Logic, Live, or Cubase).
If you install Pro Tools software, these drivers
are installed automatically. If you are not
installing Pro Tools, you can download the
driver installers from the Avid website
(www.avid.com)
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
overheating very quickly, which can
permanently damage sensitive components.
For complete installation and
authorization instructions, see the
Pro Tools Installation Guide that came
with your Pro Tools software package.
For instructions on installing the Core
Audio driver, see “Installing the Core Audio
Driver” on page 15.
For instructions on installing the ASIO
driver, see “Installing the ASIO Driver” on
page 21.
