Hi there,
Cue on for a channel I use, I touch the back panel of the mixer and a weird noise/hum appears in my headphone. It goes away if I touch the back panel with an other hand, or if I stop touching the back panel.
Similarly, cue on, I touch the plate of the turntable, hum appears. At the same time I touch the back panel of the mixer with my other hand, hum goes away.
I'm pretty sure it is something to do with the grounding and I miss some very basic knowledge here, so sorry for my ignorance, but if anyone could help me how to fix it that would be highly appreciated!
