Need a little advice before I buy the wrong cables and waste my money. I'm moving from analogue to digital and to be honest, the cables are a little confusing. I play in a band, you need to know about XLR or TRS and I'm your man, but home hifi is not my arena. I would like to connect my computer: And my TV: To my speakers: I think the pc is straightforward (famous last words), do I just need a plain optical cable? But what about the TV? To me, a coaxial cable is like a TV aerial cable, that's not right is it? What kind of cable do I need? The connectors looks the same as each other, but they're labelled differently. Thanks!
