Based on your location, your system was most likely sold and installed by Grand Stage, DesignLab Chicago, or Chicago Spotlight. And you're not far at all from the factory of one of the two best lighting companies in the world, ETC. Find "the dimmer room" or where ever there's a rack like [user]gafftaper[/user] posted. There'll be a nameplate on it, somewhere.
No, that's the outlet box; the actual dimmers are in a room somewhere, or maybe in a corner backstage, in a rack. Since you have wall panels, you have a fairly sophisticated system. Do your panels look like the attachment below?
Take and post pictures, and we'll help you identify whom to call.
Who's the second best lighting company in the world?
