  • Page 10: What Are Soundpals

    Remote Control (if applicable) Specifications 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 processing functions. The following SoundPals modules are described in this guide: •...
  • Page 11 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 digital-to-analog conversion or microphone pre- amplification. In this way, each module functions as a perfect low-cost adjunct to larger mixing consoles (such as the Graham-Patten D/ESAM series) —...

  • Page 12: Documentation Conventions

    The following documentation terms are used throughout this guide: • “Input” refers to a SoundPals module input, either analog or digital. An analog input is a single monophonic track from an analog audio source; a digital input represents two tracks (stereo, left and right) from a digital audio source.
