A strong warning on the CQ4You interface when in demo mode, or even a way to lock it out. Members of the band have repeatedly selected the demo mixer in place of the real one at gigs, and then apparently been fooled by the flickering levels, and the fact that the engineer has pre-set some levels to their mix, then complained the faders aren’t working. It has taken some time to troubleshoot this…
Better that than to accidentally take control of someone else’s mix or accidentally maxing either their output or a channel level to the point of screeching feedback!
I’m thinking about putting a limiter on the tablet controlled Aux outputs.
The solution here is better education of the people operating the mixer.
