Thank you for asking. The key points for convert stereo audio to digital audio are: 1. to extend the delivery distance between the audio source and your audio power amplifier system. 2. Typical applications consists with newer televisions or displays with digital audio that need to be hooked up to older devices with analog audio, such as VCRs and karaoke machines. Take your analog device and plug in your RCA stereo audio connection into the converter. 3. to enhance and to improve the audio quality/ audio processing for audio mixing, and music editing. conclusion: it is small, but very useful and powerful. Especially for RV traveling car use.
