I have a Creative DDTS 100 decoder and I plan on getting the Harman Kardon HKTS 7 5.1 speakers. I am not entirely sure how to connect the two however. The creative ddts has three outputs, front, rear and centre/subwoofer outputs, I believe these are minijack sockets. The Harman Kardons have three inputs, these appear to be RCA Phono and it has inputs for sub, right and left. Is there an adapter anyone can recommend? How do I go about connecting the decoder to the speakers? any help is much appreciated.
