Hi. I am also having this same problem. We have been using the mixing link in our live shows for about a year now and all of the sudden it’s become really noisy. I don’t believe it has to do with the set up as we have been using it with no noise for a very long time. DI/LINE out is set to DI. High boost is not on. Could there be a part that goes bad? Any help would be appreciated as this unit is not cheap. Thank you.
