Do the big lighting systems still use electromechanical devices? I'm assuming it's moving to DMX control with silent triacs or small relays inside the instruments that just go >tick<.
Contactors are still widely used, but more and more LED fixtures are being installed, and they are pretty much silent. Even modern contactors are pretty quiet. I've heard some new ones that are so quiet that I thought they weren't working.
