Ok so ive got a behringer vmx 200, yeah i know i shouldnt have got it and its bollocks but i was having a mix and suddenly the left deck has now decided to not play out of one of the headphones. So basically: Right deck plays fine out of both. Left deck only plays out of left headphone. Ive tried different headphones so ive come to the conclusion its my mixer. Anyone got any ideas on how to fix this or if its something else going wrong? Might just be an omen to buy a new mixer.
