Introduction
You can expand your Pro Tools|HD® system by
adding Pro Tools|HD cards, either directly in the
computer or using an expansion chassis. Ex-
panding your Pro Tools® system will provide
increased track count, add to the amount of pos-
sible plug-in and mixer processing, and let you
connect additional audio interfaces.
Pro Tools Expanded Systems
Without an Expansion Chassis
It is possible to install as many as five Pro Tools
cards in some computers.
If you require more PCI card slots than your
computer has available, you can use an expan-
sion chassis.
Pro Tools with an Expansion
Chassis
You can use a Digidesign 64-bit Expansion
Chassis, a Digidesign Expansion|HD Chassis, or
other Digidesign-qualified expansion chassis to
increase the number of PCI card slots for your
Pro Tools system. Expansion chassis will use
only one PCI or PCIe card slot in your computer,
and provide multiple PCI card slots in the chas-
sis itself.
Expansion chassis consist of a chassis that pro-
vides additional slots for your Pro Tools|HD
cards, a host card (installed in your computer),
and a cable that connects the host card to the
controller card. Some chassis also include a con-
troller card that is installed in the chassis, while
some newer expansion chassis have a built-in
controller that does not need to be installed.
For a list of system requirements for maxi-
mum track count, visit the Digidesign
website (www.digidesign.com).
Check with the manufacturer of your chassis
for details on the cable requirements for your
equipment.
