What are SoundPals? 

Each Graham-Patten SoundPals module is essentially a digital audio 

building block 

that can be 

used independently, or interconnected to perform more advanced mixing and audio processing 
functions.   

SoundPals can be used in both standalone and system configurations: 

  In a “standalone” configuration, each SoundPals module is designed to perform a specific 

audio processing function such as ADAT-to-Analog conversion.  In this way, each module 
functions as a perfect low-cost adjunct to larger mixing consoles (such as the Graham-
Patten D/ESAM series) — for single-purpose processing tasks.  

  In a “system” configuration, SoundPals can be 

linked 

to form more comprehensive digital 

audio tools.  For field recording, studio applications, and workstation applications, 
SoundPals can be used to seamlessly perform functions that would otherwise require 
extensive peripheral gear.  Best of all, SoundPals “systems” can be re-configured quickly 
and easily — to suit your changing audio production requirements.  

All SoundPals modules are extremely compact, rugged, and identical in size for ease of 
installation, interconnection, and use.  In addition, SoundPals support AES3id.  This allows 
longer, more robust AES signal distribution using standard coaxial cable.  Error free distances of 
1000 feet can be attained using inexpensive coaxial cables.  

Documentation Conventions 

The following documentation conventions are used in this guide: 

  Buttons, knobs, connectors, and switches are indicated in bold-faced capital letters.  For 

example:

Signals and Values 

Note the following important information regarding audio signal level: 

  AES3 = Balanced output with 2 channels of digital audio (left and right) 

  AES3id = Unbalanced output with 2 channels of digital audio (left and right) 

Warnings 

Please observe the following important warnings:  

 

  Heed all warnings on the unit and in the instructions. 

  Do not use this product in or near water.  

  Route power cords and other cables so that they are not likely to be damaged.  

Disconnect power before cleaning.  Do not use liquid or aerosol cleaners; use only a 
damp cloth.
