Hi all. I have been given a pair of Time speakers. At the front there is the on/off button, Volume, treble, and bass sliders, and a headphone jack hole. At the back there is the DC in, Mic jack hole, and three single wires, one going to the other speaker, and two others with stereo jack plugs on. Could someone please explain what I need to do with the two stereo jack plugs? Thanks for listening. ATB Gary.
