Flashing lights PRX 812W

What would cause a couple of our flown JBX PRX812W cabinets be displaying flashing Mic lights, channel 1 && 2 ??


  • Hold down Mic button until they go out- if you use a mic directly in that jack make sure it is lit- but be careful with the volume while doing this- make sure it is down. I have seen where others say it actually has 3 input sensitivity settings vs. the 2 mentioned in the user manual- I wish JBL would validate this because I have one stack louder than the other and I'm thinking I need to do a hard reset on one of my subs now to get things back right. I had to turn the mix out down to 12 oclock on the soundcraft board to even things out this weekend.
