Chapter 3: Using Your System 27

2 Choose the Playback Engine that corre-

sponds to the master Digidesign card in

your computer (MIX, d24, etc.). Refer to

the Pro Tools System Installation Guide if you

need more information.

3 If you have a MIX or d24 card, click the

Interface Port pop-up and choose the port

that your ADAT Bridge I/O is connected to:

• If you have a single ADAT Bridge I/O port

(Group A on ADAT Bridge back panel)

connected to your card, choose port A.

• If you have both ports (A and B) con-

nected to a MIX or d24 card with the op-

tional 16-Channel Peripheral Cable

Adapter (the Y-cable), ﬁrst conﬁgure in-

terface port A then conﬁgure interface

port B.

4 Click the Interface pop-up and choose

the appropriate interface that is connected

to the card you selected in the previous

step. If you have a MIX or d24 card with a

single ADAT Bridge I/O connected to it,

choose ADAT Bridge A. If you have both

ADAT Bridge I/O Group A and B ports con-

nected to a MIX or d24 card (with the op-

tional Y cable), ﬁrst choose ADAT Bridge A

(1-8) for the one connected to port A.

Then, click the Interface Port pop-up,

choose port B, and choose ADAT Bridge B

(1-16) as the interface connected to port B.

5 Click the Sample Rate pop-up and choose

the appropriate sample rate, 44100

(44.1 kHz), or 48000 (48 kHz) for the cur-

rently selected card and interface. This

should be conﬁgured from the primary

card/audio interface settings.

ADAT tapes are typically formatted at

48 kHz. Make sure you choose the sample

rate that matches the material that you

plan to work with. If the Pro Tools sample

rate doesn’t match that of the ADAT tape,

pops and clicks may occur during record-

ing/monitoring.

6 Click the Sync Mode pop-up and choose

the appropriate sync mode. Your choice de-

pends on which device in your setup you

want to make the master clock device. See

“Sync Mode Options” on page 28 for de-

tails.

7 Click the Digital Format pop-up to

choose the digital format (AES/EBU or

S/PDIF) for channels 1-2 of the currently se-

lected interface. If a digital device is con-

nected to both the AES/EBU and S/PDIF

ports of your interface, this pop-up allows

you to choose which port the ADAT Bridge

“listens to” for digital audio input and

word clock input. Only one port can be

used at a time.

8 Click the Ch 1-2 Input pop-up to select

the input format of channels 1-2 of the cur-

rently selected interface. When conﬁguring

the Playback Engine and/or Hardware

Setup for the ADAT Bridge, do one of the

following:

• Choose ADAT to select optical input

from the ADAT. In this conﬁguration, all

8 channels of the attached ADAT optical

device will appear in Pro Tools.

• Choose Digital to select digital format in-

put from a DAT deck or a word-clock

generating device. When Ch 1-2 Input is

set to Digital, channels 1-2 will carry data

from digital port (either AES/EBU or

S/PDIF, whichever format is selected),

and channels 3-8 will represent the data

from the ADAT.

9 If you have additional interfaces, conﬁg-

ure them in a similar manner.
