CHAPTER 3: TRANSFERRING
DIGITAL AUDIO
3.0 AI-1 TO ADAT
Recording from an AES/EBU or S/PDIF source through the AI-1
onto ADAT involves a few very simple steps. First, put the ADAT(s)
into Digital In mode by pressing the DIGITAL IN button (the button
will be lit). Next, the digital source must be selected. Then, choose
the tracks you wish to record to. Finally, adjust the sampling rate, if
necessary, to suit your needs.

3.0A Source

On the AI-1, you must set the source to either AES/EBU or S/PDIF,
depending on the actual source you are recording from. This is done
by pressing either the AES/EBU or S/PDIF button in the SOURCE
section of the AI-1 front panel. When pressed, the button will either
light solid or flash to indicate the source you have selected. Only
one of the Source buttons can be selected at a time.
• If the selected Source button's LED lights solid, it means that an
AES/EBU or S/PDIF device is connected, and the AI-1 is
receiving its clock information. Simultaneously, either the 48kHz
or the 44.1kHz Destination Rate LED will light, indicating the
source's incoming clock rate.
• If the selected Source button's LED flashes, it means that either
no device is connected to the selected input, or the clock
information is not being provided by the source to the AI-1, or
the clock information provided by the source is neither 48kHz or
44.1kHz.
Note: If the Source button's LED flashes, neither one of the
Destination Rate buttons will be lit, indicating that the AI-1 does
not detect any clock information from the source to synchronize
to.
Note: The AI-1 provides two types of connectors for S/PDIF devices.
When the Source is set to S/PDIF, the AI-1 will first look at the
