If I touch the switch in the center of the mixing-link it makes kind of ground noise, but only if the switch is in the central “MIX” position.
It happens with something plugged in or also just with the headphones connected.
It doesn’t happen when the output is going to an grounded amplifier. But I think it should work without that problem just with headphones!
I just got the unite second hand.
It’s not a really big problem, bit it’s a little annoying and I imagine touching that switch (metal!) during a concert, when connected to a loud PA, uhhhh….
Is this a common thing?
I guess it could be a faulty soldering…(switch to mass)
