Hi sorry I'm a complete amateur with these things! I've recently taken over a room which has speakers in the roof. However, I do not currently have any cable to go into a socket in the wall to connect to something like my laptop. I'm assuming that I have to connect a cable into the red and black sockets and that the cable has to have a headphone jack at the other end to connect to my laptop... but I've no idea which cable I need to buy for this?
I'd really appreciate any help with this - thank you so much in advance
