This page collect all the technical documentation produced by Audiomatica during the years. Documents are divided in categories:
- Application Notes are practical case studies using CLIO features
- Technical Notes are related to hardware and software issues
- Papers and Presentation is a collection of several presentation held around the globe
- Miscellaneous section contains older and outdated documents but still of interest
Instructional videos are available at the Instructional Videos page.
Most of the CLIO 10, CLIO 11, CLIO 12, CLIO 13 and CLIO X 14 documentation applies with minimal differences to anyone using a CLIO fw-01, CLIO fw-02 or CLIO fw-03 box.
