S/PDIF
– The Sony/Phillips Digital Interchange Format is a serial bit-stream that
has a clock signal embedded in the data stream. When recording from an S/PDIF
source, whether via optical cables or RCA cables, Layla3G & Gina3G will utilize
the synchronization clock that is embedded in the S/PDIF while they decode the
bit-stream. Layla3G & Gina3G can only sync to S/PDIF clock if the master device
is set to a sample rate between 30kHz and 100kHz. Otherwise you will get noise
and/or loss of sync.
Note:
When recording from a S/PDIF port, you must select
S/PDIF
as the
input clock. For greater flexibility, this is not done automatically. If you
find that your S/PDIF recordings contain pops or skips, be sure that you
have selected
S/PDIF
as your input clock.
ADAT
– The Alesis ADAT optical interface can send and receive up to 8
simultaneous channels of digital audio data over fiber optic cables. Unlike wire
cables, fiber optic cables do not add noise or interference. Layla3G & Gina3G can
send out (or “master”) ADAT clock as well as slave to it. If you want Layla3G or
Gina3G to slave to an ADAT clock, just set the input clock to the
ADAT
setting.
Layla3G/Gina3G can only sync to ADAT clock if the master device is set to a
sample rate between 40kHz and 50kHz. Otherwise you will get noise and/or loss
of sync.
Note:
To preserve the high audio quality of Layla3G/Gina3G’s converters it
is best to use the
Internal
input clock setting instead of synchronizing to an
external ADAT clock, which may add unwanted jitter to the signal.
Now let’s take a look at some sample configurations and how you might set them
up from a synchronization standpoint.
Let’s start with a simple example. Suppose that Layla3G is the only audio device
used in your system. Since you have no other devices to synchronize with, simply
select
Internal
for Layla3G’s input clock. Layla3G will then use its own clock to
control its operation.
Now a little more complicated set-up: You have two Layla3Gs connected. Simply
set Layla3G #1 to
Internal
for its input clock. Now connect the first Layla3G to
