I seem to have a buzzing noise coming out of Output 1 L+R. I'm trying to figure out if there is a specific issue that can be fixed or if the unit has some sort of fault and needs to be replaced. I am running TRS cables to my mixer. I only seem to get this issue on Output 1. Outputs 2 and 3 are clean. I notice there seems to be crosstalk. When I play patches going to out 2 or 3, I will see the signal light for the to 1 channel slightly light up.
I swapped cables around on the inputs and outputs and found the issue doesn't follow the cables. If I unplug it or put it in sleep mode, the noise goes away. The noise comes back when all of the lights fire up when starting the synth back up. Sounds kind of like a ground loop buzz of sorts. While I don't hear it at lower volumes, I don't have to bring the levels on my mixer much to notice it.
Any ideas on what's up and if this is something that can be resolved?
