[SOLVED] Output to monitor from djm850

Hi, i have a djm850, i only have 1 active / powered speaker in my small studio, i would just like to make sure I'm fine to only have 1 speaker with 1 cable coming from my djm and i don't need a cable from each xlr socket into a speaker each? I don't want to fry my mixer if I'm supposed to have both left & right connected to a pair or speakers.

Hope this makes sense! Thanks Tom
