Happy New Years fellow Djtt formers

I was having an audio issue during my NYE set One of my monitor kept cutting off and on .. First thing I did check all the wires connected proper they were then I turned off the wifi to my mac book and still did not fix the issue. I was using my Mac Book Pro, Trakor S4 , and 2 Mackie Mr5's if any one any info to help me please reply
