I had this hooked up with 2 sets of speakers, a cd player, tape player and phono and it all worked. I do not know a lot about these things…but..it powers in and the music plays from it. Lol I know there’s a lot of intricacies when it comes to hifi. So I’m listing it as used and working. Because that’s what it does. It served me well over the years. The point of me saying all of that is because I don’t want someone to get it and say “it’s not working as good as the one I used to have” blah blah. Everything works button wise and it plays all outputs that you plug into it. All I know The tuner works aswell but I never could get proper antenna hooked up to it to get all the stations but it works. Getting rid of because I got a nice JVC with a remote that’s black and matches my other equipment. Any questions please ask, I’m sure I provided enough pictures for you all to gather any additional info that may be written in it somewhere.
