Technical Swag


     In an effort to try and make this web site useful for the viewer and not just a sales engine, this technical section is offered to assist DIY enthusiasts by providing information and ideas for pro audio DIY projects. All of the info here is downloadable for personal use but please do not post this material to another site without permission. Linking to the pages is fine. There are other projects in the works so this collection will grow as time and funds permit. I'll try to include information that is not found at other sites. Most of the papers here have had the resolution reduced for easier web management. Some papers have hi-res versions available on DVD at a nominal cost. The projects covered have a range of skill levels and some of the voltages are high enough to cause injury or even be fatal if handled carelessly. Please use caution and obtain assistance when needed.

         version. Here  is  a DIY building
         project that doesn't require a
         mortgage or engineering degree
