Installing Pro Tools HD
Software and HDX Hardware
Drivers
Once you have installed your Avid HDX cards
and connected your Avid HD audio interfaces,
you can install and authorize your Pro Tools HD
software (sold separately).
To use your Avid HDX hardware with Core Au-
dio (Mac) or ASIO (Windows) compatible digi-
tal audio software (such as Logic, Live, or Cu-
base), you must first install the hardware
drivers for HDX. If you install Pro Tools HD
software, these drivers are installed automati-
cally. If you are not installing Pro Tools, you can
download the driver installers from the Avid
website (www.avid.com)
Configuring Your Pro Tools
System
After you have installed, authorized, and
launched Pro Tools, you can configure your sys-
tem to meet the specific needs of your studio.
For detailed information on configuring your
Pro Tools software, see the
Pro Tools Reference
Guide (which is available from the
Help
menu in
Pro Tools).
HD audio interfaces need room at their
sides to maintain proper air flow for cool-
ing. 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, which can permanently damage
sensitive components.
For complete installation and authoriza-
tion instructions, see the
Pro Tools Instal-
lation Guide that came with your Pro Tools
software package.
For instructions on installing the Core
Audio driver, see “Installing the Avid
Core Audio Driver” on page 27.
For instructions on installing the ASIO
driver, see “Installing the ASIO Driver”
on page 35.
