from another digital source:
1. Press and hold the SET LOCATE button;
2. Press the DIGITAL IN button;
The ADAT's display will momentarily read "int" indicating it will
use its own internal clock at all times, even when the DIGITAL IN
button is enabled. When you wish to record from the AI-1 again
(from an AES/EBU or S/PDIF source), you must set the master
ADAT back so it synchronizes to the incoming digital source's clock.
This is done by repeating the steps above (the ADAT's display will
momentarily read "diG" indicating it will use the incoming clock
from the digital source).

3.3L AES/EBU to AES/EBU

In this configuration, the AES/EBU jacks are used to connect two
AES/EBU devices through the AI-1. This scenario would only occur
when you wished to use the AI-1 to perform sample rate conversion
between the source and destination devices. The proper control
settings for this operation are as follows:
Source = AES/EBU
Destination = AES/EBU
Destination Rate = 48kHz or 44.1kHz (opposite from the
source's sample rate)
