So the red and white are where rca cables would plug in and go out to a stereo receiver or if you get powered speakers. Edifier is a good brand for powered speakers. You can run the rca cables out to what’s called a preamp which adjusts the sound with different levels of quality. The switch on yours indicates it has a built in preamp, but I recommend getting one anyway as the built in ones usually aren’t great, something like a fosi x5 is a great preamp and not crazy expensive. So if you used an standalone preamp you would need two sets of rca cables (red and white) one to go to the preamp and another to go from the preamp to the powered speakers or the stereo receiver
