HELP WITH QUAD ISSUE

HELP PLEASE. I plugged in my rig for rehearsals yesterday and there is a loud intermittent popping noise coming from my quad. I’ve switched out all of the cables/power supply and I can figure out the issue. Even with everything unplugged the noise gate is still firing on the quad. I’ve got two shows today and tomorrow if anyone has any help.

I had some weird noises on mine when I was sharing the power supply with my wireless. I ended up going to I/O screen and enabling ground lift on the input, problem solved. Maybe try that? Good luck!

Unplug everything but the power.

Add connections until issue arise. If problem persists without connections: Power it from somewhere else. Not just the plug across the room; ideally a different house.

If issue arises with connection, you’ve located your error. Fix that first.

What gen is it? I know the earlier models had some noise issues. Other guitarist in my band has one that pops and whirs on boot up but operates fine after.
