They stay off and I have run up the hill and turn the dsp back on again. Could you explain your theory? Honestly not sure about what this means.
You either need to do some troubleshooting of the wiring yourself, or you need to provide much more complete information about what is going on.
Exactly what button do you push to mute the mics in question? What is the console? What is the DSP? Is there possibly a remote control set up to turn off the DSP from the console so at the end of the day no one has to go do it? What outputs of the console are driving each of these speaker systems?
Al this is important information to help you solve your problem.
