DigiLink Connections

The DigiLink cable connects Pro Tools|HD cards

and audio interfaces. A single Digi-Link connec-

tor carries up to 32 channels of bidirectional au-

dio information. These 32 channels are broken

up into 2 groups of 16 channels: Group A =

Channels 1–16, Group B = Channels 17–32.

The maximum number of DigiLink cables sup-

ported on a single system is ten (for session sam-

ple rates up to 96 kHz) or eight (for session sam-

ple rates of 176.4 kHz or 192 kHz).

 Use the 12-foot DigiLink cable included with

each Pro Tools|HD card to connect the card to a

Digidesign audio interface. The primary audio

interface, which functions as the Loop Sync

master for other interfaces in the system, must

be connected to the HD Core card. You can pur-

chase optional DigiLink cables of differing

lengths (25-foot, 50-foot, and 100-foot), de-

pending on the needs of your studio configura-

tion.

 Use the 18-inch DigiLink cable, included with

each Pro Tools|HD audio interface, when con-

necting a secondary Pro Tools|HD audio inter-

face to the Expansion port of another

Pro Tools|HD audio interface.
