yes old system connected to the tv but there are no connections for it on the new tvc so would need amp i think ,someone left a surround system on my doorstep (not a clue who left it ) but linked this up to the sky+ hd box using the red and white rca leads worked but not able to adjust the volume (no remote)and it wasn't proper surround sound just stereo have since found out my new tv doesn't have a optical out only hdmi outputs/scart/usb/ i am thinking i might have to buy a new system but will it connect without the optical output?
