Synchronization – all products
only sync to S/PDIF clock if the master device is set to a sample rate
between 30kHz and 50kHz. 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
– (Layla24/Mona/Gina24) 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. Layla24/Mona/Gina24 can send out (or “master”) ADAT
clock as well slave to it. If you want the interface to slave to an ADAT
clock, just set the input clock to the
ADAT
setting. Layla24/Mona/Gina24
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 Layla24/Mona/Gina24’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.
Esync
– Esync is a proprietary form of super clock that is used to
synchronize two or more Echo 24-bit products like Layla24, Mona, Gina24,
and Darla24. While Gina24 and Darla24 have both input and output
connectors on their PCI cards, Layla24 and Mona only have the Esync
output connectors, and Mia has no Esync connectors.
Layla24/Mona/Gina24 is always outputting Esync clock.
