Whenever I'm playing at a Club and load a song to either the left or right deck, everything works flawlessly. Whenever I'm doing a private gig and have to provide sound, and lighting, loading a song on SDJ the WAV files start lagging, or in some cases have a slight latency. ( yes I adjust everything in the setting to help prevent latency, but still seems to find a way to lag ) I'm pretty sure I know the correct reasoning, which would be too many things being plugged into one circuit. But I guess I was just curious if anyone else noticed this problem, and if you have ran into the same situation, how have to prevented it.

P.s. I use a 62 and turntables/ have an i7 MacBook pro w 750 gb hard drive, 8 gb RAM
