I have recently bought a Harman Kardon HKTS-7 5.1 Home Theatre speaker system, which I intended to hook-up to my existing TV and DVD to improve the sound quality and experience of watching tv movies and dvd’s. However, the manual for the speaker system refers to connecting it to a ‘receiver’, which I imagined was the DVD or TV, but I am now not so sure. Does this speaker system need a separate ‘receiver’ unit to get it to work? If so, can you advise the best (or most cost-effective) type. The speaker system itself was over £300, so I don’t want to have to spend too much on yet another unit, but if needs must, then so be it. My TV is a Philips Plasma (model 42PF9631D) and DVD is Samsung (model HR755). My other concern is the end cables for the satellite speakers are bare cables, with no plugs – and these do not fit any of the sockets on the TV or DVD. Forgive my ignorance. I feel very confused by this system and just want to get it working.
