Tracks can be bounced between machines in a multiple ADAT system by
using the ADAT Optical digital bus. The digital bus is connected in
much the same way as the sync cables, and should be done in the same
order. Refer to the section entitled Digital In/Out in chapter 3 for more
information on connecting the digital bus. It is also possible to bounce
tracks within a single XT20 without the need for connecting the digital
bus using the TRACK COPY feature. See chapter 4 for more
information.
If the [DIGITAL INPUT] button is pressed, the XT20 will record from
the [DIGITAL IN] connector, and the analog inputs will be ignored
(both balanced and unbalanced). Alesis' proprietary multi-channel
digital bus carries the 8 tracks of a source XT20 or ADAT. All 8 channels
are sent in a one-to-one relationship to the 8 tracks of the target
machine which can record the digital audio.
Note that to create an exact (sample-accurate) digital copy from a
master to a slave, both master and slave machines must have their
[DIGITAL INPUT] buttons enabled. This is necessary so that the
master knows you are making a digital copy and will offset its digital
output so that it matches that of the slave machine.
If [DIGITAL INPUT] is selected and there is no optical input, the
DIGITAL icon (located in the INPUT icon group) will flash.
When bouncing audio from a master XT20 to a slave XT20, the slave
does not need to have its Clock set to DIG since it is already getting
accurate clock information from the master via the 9-pin cable (shown
by EXT in its display) so it is sample-locked to the digital audio it is
recording.
