Can anyone direct me to where I can get help with an issue with our Monitor feed intermittently going out and coming back on? We are running a keyboard, 2 singers and 2 drum mics. Sometimes it just goes out and sounds like its being muffled…the mains stay on throughout and are not affected. When I talk really loud sometimes it kicks back on like the power surge makes it connect again or something? Totally random too. Sometimes it does sometimes it does not??? Thanks, Jason
