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 Layla24 is the only audio device 
used in your system. Since you have no other devices to synchronize with, simply 
select 

Internal

 for Layla24’s input clock. Layla24 will then use its own clock to 

control its operation. 
 
Now a little more complicated set-up: You have two Layla24s connected. Simply 
set Layla24 #1 to 

Internal

 for its input clock. Now connect the first Layla24 to the 

second one via a BNC cable running from Word Clock Out on Layla24 #1 to Word 
Clock In on Layla24 #2. Now select 

Word

 for Layla24 #2’s input sync. The 

second Layla24 will slave to the first one and your Layla24s will now operate in 
unison. 
 
No matter how many devices you are synchronizing, the concept is essentially the 
same. You are merely “daisy-chaining” devices together using compatible clocks. 
One device will operate as the source of the master clock, with each successive 
device using that clock to sync.
