problem with immediate blackout

Hi everyone, I got a little problem, when I put down a slide quickly the blackout is not immediatly but there is a little delay, something like 1 sec. Do you know if it could be a setting stuff? Thank you.

  • If this is happening with incandescent light sources, you might be seeing a combination of the fast fade on the dimmer and the filament losing power to the point of no longer being able to illuminate. This is a natural phenomenon and can not be corrected. 

    Or am I misunderstanding and are you saying that you pull the fader to zero, nothing happens for a second and then it fades out? If this is the case can you explain a bit more about your system?
