A:Answer There are two AUX inputs on the LG 200W Hi-Fi Shelf System with CD, Cassette and Bluetooth® Connectivity, Model # CM3370 that you can use to connect your turntable to. However, depending on your turntable, AUX inputs are near to line-level and are not the same as PHONO jacks that are designed for phonograph turntables. A line-level signal is approximately one volt, or about 1,000 times greater than a signal from turntable. Connecting a turntable to a line-level input will result in almost no sound at all because the turntable signal is so faint that the line input cannot hear it. Turntables need a special preamp in order to work. The PHONO input has this built in. You can only plug a record player into a PHONO input. Some record players have this preamp built in, therefore you can plug them into an AUX, and plugging them into PHONO will not work. AUX is a line level input which you can plug any audio gear into. If you don't have a PHONO input on your receiver you can get an outboard "phono preamp" to plug between the record player and the receiver...^IFV
