but be aware that operating
alongside
another product is not the same as
operating
with
it. In order for accurate synchronization to occur, the other
audio product(s) in your system must support a synchronization mode that is
compatible with Layla24. Without such synchronization, the individual
pieces of equipment will act independently of each other. This scenario may
be fine for some musical applications; however, it is not appropriate for
situations where sample-accurate synchronization is required.
For this reason, Layla24 supports many synchronization modes. Layla24
can slave to Word clock, S/PDIF, ADAT, and MIDI Time Code (MTC). In
addition, Layla24 can also generate these synchronization signals and
Esync, as well as perform translation of one clock to another, such as
transmitting Word while reading ADAT.
Let’s take a brief look at the various synchronization types.
Word Clock –
This is a synchronization signal that connects to the BNC
connector labeled
Word Clock
on Layla24’s back panel. This
synchronization clock runs at the selected sample rate. Think of it as a kind
of electronic metronome, which clicks back and forth at the digital sample
rate. It is one of the most widely used forms of synchronization in digital
audio. Layla24 is always generating Word Clock on its Word Clock output
BNC connector. Although it can generate Word clock at any sample rate it
is set to, Layla24 can only sync to Word 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.
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, Layla24
will utilize the synchronization clock that is embedded in the S/PDIF while
it decodes the bitstream. Layla24 can 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.
