Hi all....Not sure if this is the right place for this,but I got my Mackie 12 channel out of the closet the other night . It was going along just fine when it began to squeal. All the zero level lights came on and no sound. Adjusting any of the volumes had no effect on the noise. It stayed at the same level ..I turned it off for a couple mins and turned it back on. Worked fine for a couple mines then same thing....Any ideas? hate to lose it........Thanks
 
Unless you've accidentally created a feedback loop, it sounds like a power supply problem inside the unit, and/or a coupling cap has gone haywire. Most likely have to find a qualified repair person if you aren't electronics repair savvy.
