I work at a church and our Avantis has at least one Phantom Fader. It could the DCA Spill and Accidental Adjustment, but wondering if there’s any setting that would cause a fader to move without the mixer’s knowledge. Example: We have one fader that can control all the handheld microphones as a group. One Sunday, we could not hear the singers and during our troubleshooting, we discovered that group fader was all the way down. The mixer reported not having touched it.
A scene change could certainly do that.
