The Sony PSLX300USB is identical to normal turntables, with one exception. In addition to having standard RCA phono outputs, it also has a USB output that instead of emitting an analog phono level signal, sends a digitized version of the analog level signal. When this turntable is connected via the USB connector to a computer running an audio capture program ( Audacity ), a digital conversion of sounds coming from the record on the turntable is saved. Subsequent to the digitization of the recording, addition tools in Audacity can be used to remove imperfections resulting from surface dust and scratches from the digital representation.
