Hi Ive just hooked up my new gear and there is a really anoying constant buzzing comeing through the speakers! Everythings conected correctly (I think). Everytime I touch the Mixer or the amp when it's all turned on the buzzing changes slightly


any help would be appreciated I just wanna get them fired up
This is my set up
Amp & Speakers:Citronic HS120USB
Turntables:Stanton T.60
Mixer:numark DXM01-USB
