GARY STANLEY'S PROJECTION & SOUND SERVICE
Englewood, Colorado

The auditorium control panel-the 4 buttons on the far left control various dimmer settings, the 2 toggles control remote framing and focus of the projector (!), the 3 buttons to the right of that control the masking positions, then of course are the volume and format select controls, with live feedback so you can see the status of the cinema processor, and the 2 buttons on the right start and stop the projector.
