XDJ-XZ Causing clicking sound in speakers

recently purchased xdj-xz. i am  getting clicking / crackling via the speakers as if there is a loose connection, this seems to only happen when playing via Rekordbox from my laptop. It also happens when i turn any of the knobs, nudge the deck plate or press on the pads. Sometimes happens even without touching anything.

 

I was using the same speakers and cables with my previous xdj-rx2 with no issues. All i did was plug in the xz and noticed this.

I have tried adjusting buffering size but no luck, any ideas? Software and firmware up to date.
