i get a slight hum when i use TC bypass, my TT are grounded to the pc as should be and also to the mixer( a split wire) I get 100% with the TCV so i know it's good connection. its just the ground with the mixer i believe is the issue, if i take that ground off the mixer the hum is louder, so it does somethign just not doing it well.

what equipment does have a ground on powerwire ?

Mixer? Notebook ? Amplifier ?

I disconnect the third wire on the power cords and have only 1 ground (amplifier)

i meant the electrical cords. If you use only 2 pin plug it's okay
but if more equipment has 3 pin plug you got ground loop.
One thru the electrical outlet, other is going thru the ground wire on audio cable.


but i think in your case you got TT's connected and grounded both to mixer and PC
and also you have the output of your soundcard connected to the mixer.

Use LOW volume please !!! and then try to "cut" the ground connection
on the cables comming from PC to mixer (output) but the center wire will stay connected.
