I'm going to be Dj'ing at a hall Party . However im new a bit to playing live. I Have Serato Rane Sl2 . With two Record players. Im going to be renting a speaker bundle that comes with two Speakers, Sub wolfer and a "PGM8 8-ch Passive Mixer " . I Read somewhere that the SL2 Only has enough for `2` Inputs or outputs and that you require and Sl3 in order to play gigs. However im not entirely sure and cant find any Information anywhere on my exact problem.
