Pioneer DDJ-SX2 sound out put issues

Hey guys i've probably got a simple issue here, so sorry for sounding dumb/ inexperienced. Just over a month ago i got a DDJ-SX2 and i love it and it's been working perfectly. However, earlier today i went to play it and once i loaded a track sound only came out of my left ear piece on my headphones. I first thought it was my headphones but i plugged them into my computer and they both worked. Just to be safe i tried other headphones and still no luck. As i'm still reasonably new to the SX2 I'm not quite sure if I'm not seeing something on the controller. For the record everything runs as per normal except the sound output out of the left earpiece. Thanks in advance! :)
