A:AnswerGo and pick up a simple aux cord with the standard 2.5mm male jacks on both ends. Plug one end into the headphone port on your computer, the other on the front lower part of the system. And press the function button on the sound system repeatedly until it says PORTABLE.
A:AnswerThe LG - 700W Mini Shelf System - Black, Model # CM4550 does not have a "PHONO" input on it and its' inputs are what are referred to as "line-level" inputs that are designed for an input voltage of about 1 volt. CD players, DVD's, those old Cassette Decks and tuners all output line-level voltage. Moving magnet phono cartridges produce between 2.5 and 5 millivolts which is why the volume is very low. You will need to get a phono pre-amplifier that is designed to amplify the turntable's low-voltage signal to line level so it can play at the right volume on the Mini Shelf's system's inputs...^IFV
