Main left output dropout

  • My left output sporadically drops out or makes glitched sounds, then returns to normal after a minute or so. Sometimes I play for hours without issues, other times it happens within 5 minutes. I tried switching cables to see if it was a cable problem wich it was not. Also changed the audio interface to one with active metering, wich visually confirmed that I got no input from the left main out. My signal chain is Kemper main outs (1/4 Jack) -> Audio Interface (XLR) -> Studio Monitors. I'm convinced it's the Kemper, but the question is how do I fix it? Any thoughts?
