Hopefully this is an easy problem but one I have not been able to figure out on my own. So I'm trying to record my signal from my helix into my go pro hero 7 black. Now I'm running 1/4 inch out into a mixer. From the mixer I'm running RCA out into a GoPro Mic adapter. However, my signal on play back is terribly tinny and distorted. I made sure levels on mixer weren't cranked and gains not maxed. Also the volume on my Helix unit isn't maxed out either. Is there something that I'm missing??
