Alright sound guys, here's my question.  I have 24 scenes set up in my marching show.  What I would like to do is unlink the stereo out fader so that when we change scenes it is not effected.  This is so that if we discover that things are a little hot or need to be boosted at a contest we can adjust the master fader once and have it stay where we adjusted it throughout the show.  Anyone know how to do this?  I'm not finding anything in the manual or on the internet.

Any help would be appreciated!
