ADAT Bridge I/O

if, for example, you have chosen AES/EBU
as your digital format and are actually re-
ceiving S/PDIF.
Slave
When continuously lit, this LED indicates
that the ADAT Bridge I/O master sample
clock reference is being determined by an
external device connected to the Slave
Clock In port on the ADAT Bridge I/O’s rear
panel, typically another Digidesign Audio
Interface or an eternal sync peripheral. The
ADAT Bridge I/O will automatically switch
to Slave mode when a valid slave clock sig-
nal is connected to its Slave Clock Input
port and the ADAT Bridge I/O is set for in-
ternal sync in the Pro Tools Hardware
Setup dialog or Session Setup window.
3. Channel 1–2 Input
This LED indicates the source of input to
Pro Tools for channels 1–2 of Group A
and/or Group B. When the ADAT LED is lit,
input channels 1–2 in Pro Tools are cur-
rently selected to receive digital input via
the ADAT Bridge I/O’s optical port. When
the Digital LED is lit, it indicates that chan-
nels 1–2 in Pro Tools are currently selected
to receive digital input via its AES/EBU or
S/PDIF ports. When this is set, ADAT opti-
cal channels 3–8 are still sent to Pro Tools.
This parameter is set using the Ch 1–2 In-
put pop-up in the Pro Tools Hardware dia-
log or Session Setup window.
The AES/EBU or S/PDIF inputs can be
routed to Channels 1–2 of either Group A
or Group B. This gives you the flexibility to
set Channel 1–2 to ADAT on Group A, and
Channel 1–2 input to digital on Group B.
This allows you to record eight channels
audio from ADAT on group A, and two
channels of digital input on Group B. If
you wish to record a full 16 channels of au-
dio from ADAT, Channel 1–2 input must
be set to ADAT for both Group A and
Group B.
4. Sample Rate
These LEDs indicate the current sample
rate of Group A and Group B of the ADAT
Bridge I/O. If these LEDs are flashing, it in-
dicates that the currently selected sample
rate does not match the sample rate cur-
rently being received by the ADAT Bridge
I/O.
5. Digital Format
These LEDs indicate which digital port
(AES/EBU or S/PDIF) is currently being used
for digital input on channels 1–2 of Group
A or Group B.
