This video shows you how to connect your laptop to your mixer. First you will need two different sound sources from your laptop to your mixer. This is so that you can use all of your mixer functions on two different channels. The way to do this is to run a 1/8" RCA cable channel 7 from your normal earphone jack to the mixer. Also use a behringer uca202 audio interface to connect to the laptop via USB cord. This provides another earphone jack. Then use a master out cable to connect it to an amplifier. Which in turn is connected to the speakers. Then configure the software accordingly. Practice and Enjoy.
