Introduction

This is the User Manual for the ADR30 Stereo Ensemble module from Oakley Sound. This 
document contains an overview of the unit and goes into some detail regarding the operation 
of the module. It also contains the calibration instructions.

For the Builder's Guide, which contains a basic introduction to the circuit board and a full 
parts list for the components needed to populate the board, please visit the main project 
webpage at:

For general information regarding where to get parts and suggested part numbers please see 
our useful Parts Guide at the project webpage or http://www.oakleysound.com/parts.pdf.

For general information on how to build our modules, including circuit board population, 
mounting front panel components and making up board interconnects please see our generic
