Well - It's propbably clickbait spam, but the link doesn't even work!
I settled on a Scarlett Solo so I don't think I can bring my stereo mp3 source (small player not a phone) into the system as a stereo signal. The input available is a 1/4 jack for instruments. What confused me is why have a head phone jack when there is no way to get stereo into the device. I'm probably missing something. Thanks for the cable recommendation. It looks like it may be handy at some point - maybe. I will probably just play the backing tracks on my computer which should play out as stereo and not worry about not having a stereo input into the Solo. I use the computer to load these same tracks on the MP3 player anyway.He does however listen on what are perhaps the best of the really cheap 'media' speakers, a pair of Presonus Eris 3.5. These are adequately loud for him. Re recording with a backing track? Yes you will need a mixer and if the track's source is a phone, as it often is, this https://www.amazon.co.uk/Hanprmeee-...2lkZ2V0TmFtZT1zcF9zZWFyY2hfdGhlbWF0aWM&psc=is the cable you need to get stereo into the mixer.
You can record mono signals into it. Then mix them in a stereo field, then listen to that stereo.What confused me is why have a head phone jack when there is no way to get stereo into the device. I'm probably missing something.
