Does anyone use POT for potentiometer when they're on set or at work on a mixer? I just got into a huge argument with an audio guy about it. He said they are "slots" or "channels" if I like, but he'd never heard of POT? I know I'm right, but I want to know if the other pro's here run into these unschooled audio peeps a lot. Also, I know there is a thread of "best thread titles" and this is my toss in the hat.
