Using DigiTest As a
Diagnostic Tool
The DigiTest utility performs diagnostic
tests on the Pro Tools cards in your system.
To use DigiTest:
1 Refer to the DigiTest ReadMe file for the
latest operational information.
2 Restart your computer.
3 Turn down any audio outputs on your
system.
4 Locate and open DigiTest.
5 Click the Run button.
DigiTest will run a diagnostic test on your
Pro Tools cards. When the test has been
completed, the Status field will indicate
whether each card has passed or failed.
6 If DigiTest reports that any of your cards
have failed, click the Info button next to
that card. Write down the information that
appears and report it to your local Digide-
sign dealer or a Digidesign Technical Sup-
port Representative.
Performance Factors
There are several conditions that may ad-
versely affect the performance of Pro Tools.
These include:
Network Connections Close any network
connections unless you are using them for
network interchange of audio data.
Background Applications Any software utili-
ties that run in the background or generate
disk activity, such as virus protection soft-
ware, disk optimizers, or file savers, should
be turned off or removed.
Screen Savers Screen saver software should
be completely removed from your com-
puter before running Pro Tools.
Power Saver Features Some automatic
power saver features, such as those that
spin down the system hard drive, can affect
Pro Tools performance. These features
should be turned off.
Virtual Memory (Macintosh Only)
Pro Tools will not launch if Virtual Mem-
ory is active. Deactivate Virtual Memory
and restart your Macintosh.
CD-ROM Extensions/Control Panels Some
CD-ROM and removable media Extensions
and Control Panels have been linked to
audio quality problems. Deactivate any
performance-enhancing Extension or Con-
trol Panels for such media, and restart your
computer.
