Pro Tools Hardware Overview
This section describes each hardware compo-
nent of a Pro Tools|HD system. The number of
Pro Tools|HD cards in your system will differ de-
pending on your system configuration.
Pro Tools|HD (for PCIe) Hardware
Accel Core (for PCIe) Card
All Pro Tools|HD (for PCIe) systems include an
Accel Core (for PCIe) card.
The Accel Core (for PCIe) card provides up to 96
tracks of direct-to-disk recording and playback,
as well as DSP power for mixing and plug-in pro-
cessing. The Accel Core (for PCIe) card supports
up to 24-bit and up to 192 kHz sessions.
DigiLink Port The Accel Core (for PCIe) card in-
cludes a single DigiLink port for connecting up
to 32 channels of audio input and output to
your Pro Tools|HD system.
DigiSerial Port The DigiSerial port on the
Accel Core (for PCIe) card is for connecting a
Digidesign SYNC I/O. This connector is an 8-pin
mini-DIN.
Accel Core (for PCIe) card
The DigiSerial port on an Accel Core
(for PCIe) card does not support Machine-
Control connections.
