Installing and Authorizing
Pro Tools HD Software
Once you have installed your Pro Tools|HD Na-
tive hardware in your computer, you can install
and authorize your Pro Tools HD software.
For complete installation and authorization in-
structions, see the Pro Tools Installation Guide
that came with your Pro Tools Software package.
Configuring Your Pro Tools
System
After you have installed, authorized, and
launched Pro Tools software, you can configure
your Pro Tools system to meet the specific needs
of your studio. For detailed information on con-
figuring your Pro Tools software, see the
Pro Tools Reference Guide (which is available
from the Help menu in Pro Tools).
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.
