About the ADAT-4  
The SoundPals ADAT-4 is an ADAT-to-AES converter that separates a single 8-channel ADAT 
data stream on optical fiber into four AES output audio pairs, on either balanced or coaxial cable.  
AES outputs are synchronous with the ADAT input.   
The unit offers the following features:  
•  Synchronizing connector for a silent AES3id or word clock output.  This output can be 
used to synchronize other SoundPals to the ADAT data stream. 
•  Front panel switch for selecting reference output 
•  Optional rack mounting tray (1 RU) 
•  Compact size, rugged construction  
Two product models are available:  The “A” model has AES3 outputs (XLR), and the “B” model 
has AES3id outputs (BNC). 
 
The figure below illustrates the ADAT-4’s front panel:

1)  ADAT IN — the optical input is a standard ADAT signal using plastic fiber with a 
maximum range of 1 meter.  The input must have a sampling frequency between 30 and 
50 KHz. 
2)  SYNC OUT — the synchronization output can be set to either AES3id or word clock, 
depending on the position of the adjacent Sync Switch.  The AES3id output uses the 
same channel status bit settings as the main AES outputs. 
3)  AES/WCLK — the two-position Sync Switch allows you to select either AES3id or word 
clock as the sync output.   
4)  I/P ERR — this LED lights when no signal is applied to the input, or when the signal is not 
valid.  A non-valid signal exhibits errors such as format violations, bit errors, low level, or 
incorrect frequency.  When lit, the output is muted. 
5)  PWR — the large green Power LED lights when system power is applied.
