Okay, this is the worst bug report ever because I didn't get a chance to play with anything on the system as this happened during a show.
The first clue something was wrong was when the guitarist was too loud in our ears (IEM).
Okay, that's not unusual at all, but what was odd was the singer, who's hands are free, pops over to my iPad which is on a mic stand mount in front of me, changes to his aux view.
He slides the fader for the guitarist down - it doesn't turn the noise down in his ears.
The VU meter is still up high... (it's not frozen, it's just not dropping)
I switch to my view (have to stop playing bass), and do the same thing... fader goes down, volume stays up....
However, it did lower the volume - eventually. Serious lag. Like, the mixer reacted many SECONDS behind the fader movement.
Not sure if this was that iPad that was wigging out or something going on with the DL32R.
WiFi Signal was full scale (my iPad is within 10ft of the mixer and the AP.
Our FOH audio tech said that their iPad reacted smoothly. Nowwwww, maybe they just mean that the fader moved smoothly - I don't know if was affecting the volume instantly, or lagging behind like it was on stage.
This was a pretty big show and during my breaks I could not mess with the system at all, I needed to be doing other things, so I did not try to reboot the system or the iPad (besides, we were playing music during the breaks and people were dancing - no time) and there was no time after the show.
I will get a chance tomorrow to work with this system again, unfortunately, it's at another show.
Anyone else seen this type of behavior?
The only other strange thing was the power light on the DL32R was flashing red after startup a week or so back. Powering down and back up brought it up as normal.
Are there logs that are accessible?
