It’s always nice to hear from the guys that have been around the block. Mitch Hefter has been around it a couple of times (with all due respect, Mitch!). Webster and Ron and you get a lesson in standards like DALI and DMX and a refresher on acronyms like ESTA and USITT. You’ll even learn how a Norelco Razor played a part in the development of POE. Mitch Hefter has been working in lighting controls for over 40 years. He has played a major role in setting entertainment technology standards, promoting electrical safety and developing certification for entertainment industry electricians, and is an ETCP Certified Entertainment Electrician and Recognized Trainer. He is a founding member of the Entertainment Services and Technology Association (ESTA) Technical Standards Program (ANSI E1) and co‑chairs the Electrical Power Working Group. Mitch was instrumental in the development of USITT DMX512 in 1986 and chairs the ESTA E1.11 USITT DMX515‑A Task Group.
