Need turntable help

left turntable making a loud hum when turning up the bass but right turntable doesnt do it… nd its not the ground cable because plugged it into right turntable and it doesnt do it

Bad rca cables maybe

Silly question, did you try swapping over the channels to see if the right hand TT also makes the same noise when plugged into the left channels?

ground loop hum? Is there a switch on the back of your mixer with a ground symbol on it? On one side will say LIFT, the other will look like an upside down pitchfork.
