Entertainment Electrics Classes and Workshops
I'm an ETCP Recognized trainer, and my approach to the classes and workshops I offer is to tailor them for the needs at hand. I teach classes and workshops about topics relating to entertainment electrics and control systems, including setting up power distro, electrical safety, DMX, RDM, Art-Net, sACN, Ethernet, wireless DMX, console programming, lighting CAD and documentation, and more. I’ve put together beginning, intermediate, and advanced classes and hands-on workshops, most of which cover topics that came out of discussions with the organizations involved. The examples below are just a sample of offerings.
