I am not knowledgeable about setting up audio components, or electronics in general. I bought the Merak CD player bc it was advertised as compatible with my Bose radio. I don’t know how to supply the power. I see the 5V DC power input that has a USB C connector. Can I just plug that USB cord into a wall outlet ? And as long as I’m asking, do I use the line out or headphone out to connect to the Bose? I’m a teacher, so please educate me. Thanks!
