Me and my coworkers are having a Christmas party and I was appointed as the DJ. This party is pretty upscale and its going to be in a hall. Now I thought i would just be needing a laptop to play the songs with but, i am provided with speakers from the hall and now they are asking if i can set up a wireless mic.

I'm not sure what I need to plug in the Mic, speaker and laptop. I also want to make sure that the sound comes out off one output. Do I need a complicated DJ setup? Or just amplifier?
