Pro Tools 24 Hardware
Pro Tools 24 system hardware consists of a d24
audio card, a DSP Farm card, and a 5-node TDM
ribbon cable for connecting them.
The d24 Audio Card
The d24 audio card provides 24-bit, 32-track, 16-
channel I/O, direct-to-disk recording and play-
back capabilities to your Pro Tools 24 system. It
also provides a connector for attaching a single
888/24 I/O, 882/20 I/O, or 1622 I/O Audio In-
terface. If you purchase the optional 16-channel
peripheral cable adapter, you can attach two 8-
channel audio interfaces.
The DigiSerial port is for connecting an optional
Digidesign Universal Slave Driver, or a 9-pin de-
vice for use with the Pro Tools MachineControl
option.
The DSP Farm
The DSP Farm provides the power for the
Pro Tools 24 system’s mixing and processing ca-
pabilities. It powers DSP software such as the Di-
giRack plug-ins included with Pro Tools. It also
provides a connector for attaching an 8-channel
audio interface.
The TDM Ribbon Cable
The TDM ribbon cable is used to connect multi-
ple cards in your Pro Tools system so they can
share data along the TDM bus.
A 5-node cable comes with your system. If you
plan to use your system with an expansion chas-
sis, you can order a TDM cable with more nodes
from your Digidesign dealer.

to any of these cards. The optional 16-
channel peripheral cable adapter is not sup-
ported by the 1622 I/O.
