Click here for an article Jim Janninck and I wrote for Sound and Video Contractor magazine. In the nearly 4000 word article, Jim and I explain the differences between Show Control and "Media Control"systems (like AMXand Crestron). It appears in the October 2004 issue. PDF posted here.
I'm John Huntington, the author of the book Show Networks and Control Systems, and this site covers entertainment technology, severe weather, photography, and anything else that I find interesting.
