We have a SD16 stage box that partially stopped working after loosing power a couple of times in one night. All the mic inputs have stopped working - choir monitor, floor wedges, subwoofer and send to another building are all fine.
I have done the following trouble shooting:
Turned unit off and unplugged for a short amount of time;
Changed the CAT 6 cable from A to B (also at X32 board);
Plugged handle mic into all the mic lines with no signal;
Checked routing on the board with no changes;
I will turn off power and unplug for an extended period today (a few hours) to see if that helps.
Any suggestions would be helpful and appreciated.
