Recording from vinyl to rekordbox via PLX-500 speed is way too fast

Ive just purchased a PLX-500 specifically to record my vinyl however I can record but the speed of the track on playback is too fast whether I listen to it back on reckordbox or music player on my laptop. I've searched everywhere and cannot pinpoint the problem, this is very frustrating as I've tried changing setting in my preferences but the recordings are exactly the same just way too fast, can somebody help me with this please.
