Master output for speakers (output 1-2)
Your active speakers must be connected to one of the two
Master outputs for speakers located at the back of your
DJ controller.
It is possible to simultaneously use both output formats
— for example, by connecting an output pair to the PA
system, and a second output pair to monitoring
speakers.
