just checking if anyone would know....can I just use a plug/cable adapter or will I need a converter box ?
it's for the analog left and right jack outs from my Presonus monitor station, into the RCA inputs of a simple Hifi amp to power my auratone cube speakers.
 
thanks !

plug/cable adapter.  If you have time you can get one off of Amazon (Monoprice is good) for a lot cheaper than your local music store.  I don't mind buying at mine but cables are way overpriced there.  It is like they know no one is going to buy theirs except for the musician w/ a gig in an hour.

thanks AT, will buy some not too expensive cables then like you say....appreciate the advise, thank you.
