10 Click OK to close the Playback Engine
dialog when you have finished.
Pro Tools will remember your configura-
tion until you change it. If you wish to
change your Pro Tools hardware configura-
tion in the future, you can do it from any of
these locations:
• The Playback Engine dialog (in the Set-
ups menu).
– or –
• The Hardware dialog (in the Setups
menu).
In addition, several settings can be made
from the Session Setup window. These set-
tings are described later in this chapter.
Sync Mode Options
The choices you see for Sync Mode will de-
pend on how you have connected the
ADAT Bridge I/O to Pro Tools.
If the ADAT Bridge is the primary
interface
If the ADAT Bridge I/O is being used as the
primary audio interface, then the following
choices are available for Sync Mode:
ADAT as clock master Choose ADAT Opti-
cal to select the ADAT as the clock master
(ADAT Bridge must be your primary audio
interface for this choice to be available).
When the ADAT Bridge is your primary au-
dio interface, this will be the setting to use
for ADAT-to-Pro Tools audio transfers.
Pro Tools as clock master Choose Internal
to select Pro Tools as the clock master. This
is the setting to use whenever the ADAT
Bridge is not the primary audio interface (in
which case, the “ADAT Optical” choice is
not available for Sync Mode). The ADAT
should then be set for “Dig” or digital
mode (or, if you are using an ADAT syn-
chronizer, “Ext” or external). This is the
setting you will want to use whenever you
perform a Pro Tools-to-ADAT transfer, or
when the ADAT Bridge is not the primary
audio interface.
Another device as clock master Choose
Digital if you are recording digital material
into Pro Tools from a DAT deck or a digital
device other than your ADAT. In this
mode, the clock master comes from what-
ever digital device is connected to the
ADAT Bridge I/O digital inputs. You must
then use the Digital Format pop-up to
choose the digital port (AES/EBU or S/PDIF)
for the digital word clock signal. The ADAT
should then be set to “Dig” or digital sync
mode. If you own an Alesis M20, set it to
Optical.
