Question about Panasonic SC-PMX94

The stereo does not allow direct connection of a vinyl turntable, as it does not receive an audio signal as input, only as output. Although it has an audio input port, Panasonic specifies that this model can only emit an audio signal, but not receive one, which prevents the direct connection of a conventional vinyl turntable without an external phono preamp. To connect a vinyl turntable, you would therefore need a phono preamp between the turntable and the stereo system.
