In this must-hear episode, host Emily is joined again by Alex Chomsky, Technical Director at Sundrax, to tackle a topic that every lighting technician should know: galvanic isolation. From blown consoles to fried network nodes, the risks are real — and preventable.
Alex explains how galvanic isolation protects DMX systems from electrical surges, ground loops, and hardware failure, using real-world examples and practical advice. Whether you're managing a theater, a stadium, or a building façade, this episode will change how you think about signal integrity and safety.
💡 If you're running DMX, ArtNet, or sACN — and especially if you're mixing power sources or working across long distances — this episode is essential listening.
🎧 Key topics include:
What galvanic isolation is and how it works
Where to implement it: splitters, interfaces, and ArtNet nodes
Why optocouplers and transformers are your best friends
Common mistakes and real-world failures
The importance of isolating power zones and preventing ground loops
