Doesn't bang right

grounding is important if you want a clean sound. sometimes you can get by without it.

IMO, if you're running a turntable's audio that is not line-level, without a phono preamp, thats gonna be more important at this point.

what kinda tables you got? are their power plugs 3-prong?


.dope.

Ground em or you'll pick up mad background noise,feedback(UNWANTED NOIZE) especially when sampling vinyl into the MPC even with the tt grounded its still gonna pick up some distortion(like if some heavy mudd footed homeboy is stompin his feet in your "Studio" so get a piece of 12-16 gauge speaker(prefferably)wire and cut a section long enuff(BUT NOT TOO LONG---the longer the more resistance in the signal---always give ya self some slack but remember the less wire(speaker/rca/1/4'',etc) the better. connect 1 end to tha tt's grnd and one to the mixer/pre-amps grnd.
