Electronics Repair Questions? Ask an Electronics Technician
Hello, my name is Rusty. I'm an ex karaoke host. You don't need that controller, all you need is the laptop, mixer and projector. Your laptop will be the controller. I have used Roxbox, and other programs that use Winamp.
Don't over think this, all you need is the program that will play your .zip files, a connection from your laptop to your computer, and run the headphone output of your computer to your mixer.
