S/PDIF Digital In and Out

These are unbalanced RCA jacks that accept and

output a stereo S/PDIF digital data stream.

S/PDIF supports up to 24-bit audio, at sample

rates up to 96 kHz. S/PDIF input can be chosen

as the input source for channels 1–2 in the Hard-

ware Setup dialog. S/PDIF output is mirrored to

analog outputs 1–2.

To maintain data integrity and minimize

jitter, use only 75-ohm coaxial cable for

S/PDIF connections.

Loop Sync In and Out

Loop Sync is a dedicated clock signal for syn-

chronizing multiple Pro Tools|HD peripherals

together. Loop Sync uses a Word clock signal

based on sample rates of either 44.1 kHz or

48 kHz. As sample rate increases in the system,

Loop Sync continues to operate at a base rate of

44.1 kHz or 48 kHz, depending upon the higher

rate.

The Loop Sync In and Out ports are standard

BNC connectors that output a 1x Word clock

signal. Loop Sync should only be used to chain

multiple Pro Tools|HD peripherals together (au-

dio interfaces and the Digidesign SYNC HD™ or

SYNC I/O™).

For more information on Loop Sync and its con-

nection requirements, see the HD Setup Guide.

EXT. CLOCK In and Out

The External Clock In and Out ports are stan-

dard BNC connectors that receive and output a

Word clock signal. These ports can be used to

synchronize the 96i I/O to any device that re-

quires (or provides) word clock.

96i I/O Guide

External Clock In and Out are configured in the

Hardware Setup dialog.

Because the Loop Sync and Word Clock ports

pass crucial timing information, use high-

quality 75-ohm coaxial cables.

Primary Port

The Primary Port is used to connect the 96i I/O

to your Pro Tools|HD cards, or to another

Pro Tools|HD audio interface, using a DigiLink

cable.

• When the 96i I/O is the only audio interface

in the system, the Primary Port is connected

directly to the Accel Core card (Pro Tools|HD

for PCIe systems) or HD Core card

(Pro Tools|HD for PCI systems).

• When the 96i I/O is used as an additional I/O

in an expanded Pro Tools|HD system, the

96i I/O Primary Port can be connected to an

HD Accel or HD Process card, or to the Ex-

pansion port on a 192 I/O, 192 Digital I/O, or

96 I/O. For information about connecting

expanded Pro Tools|HD systems, see the

Expanded Systems Guide.

Expansion Port

The Expansion Port is used to connect an addi-

tional Pro Tools|HD I/O to the 96i I/O. Using a

DigiLink cable (one is included with each

Pro Tools|HD audio interface), another 96i I/O

can be connected to the Expansion Port for an

additional 16 channels of input.

AC Power

This connector accepts a standard AC power ca-

ble. The 96i I/O is auto power-selecting (100V to

240V) and will automatically work with a stan-

dard modular cable to connect to AC power re-

ceptacles in any country.
