I recently bought a RCA Home Theater from a pawnshop but they didn’t give me user’s guide. I am really confused about some of the RCA jacks two in particular that just say “Through” and “Out”. Anybody know what I should plug in to those? I would like to have more information about those two mystery jacks and also if anyone can tell me where I might be able to download the user’s guide as well. Thank you in advance.
