tape on another ADAT, and you avoid having to reconnect your
system.

3.0C Destination

To route the AI-1 to ADAT, set the AI-1's Destination to ADAT by
pressing the DESTINATION ADAT button. The button's LED will
be lit indicating it has been selected.

3.0D Converting Sample Rate

If the source you are recording from is already using a 48kHz clock,
the 48kHz DESTINATION RATE LED will be lit. This is the same
clock that ADAT uses, so there is no need to convert the sample rate.
If the source's clock rate is 44.1kHz, the 44.1kHz DESTINATION
RATE LED will be lit indicating that the ADAT(s) will synchronize
to the source's clock. You now have the option of converting the
source's clock rate to 48kHz, or leaving it at 44.1kHz. Either may be
done by pressing the 48kHz button (the 48kHz DESTINATION
RATE LED will be lit, indicating it has been selected), or simply by
leaving it alone (the 44.1kHz LED will remain lit).
If the source's clock rate is something other than 48kHz or 44.1kHz,
neither DESTINATION RATE LEDs will be lit, and no sample rate
conversion will be permitted. In this case, the ADAT(s) will still
synchronize to the incoming source's clock rate.

3.1 ADAT TO AI-1

The AI-1 can route up to two ADAT tracks at a time to other digital
audio recording equipment from other manufacturers, including:
multitrack digital recorders, hard disk recorders, digital effects
devices, CD recorders and DAT machines. Since the ADAT digital
bus is a proprietary multichannel interface, it is necessary to convert
the digital audio of the optic bus into a standard that is compatible
with other equipment. The two standards supported are AES/EBU
and S/PDIF. It might also be necessary to convert the sample rate of
the outgoing digital audio. The AI-1 can convert back and forth
