Is this cable a two wire system or three? I have Yamaha RX-v665 receiver and I can not get anything to come through the subwoofer.

I have to connect a VHS player, a dual cassette player, a DVD player and possibly an old fashioned LP record player, none of which have HDMI connections. Therefore, I need (or would like) to have enough analog connections to use the Old-Fogey devices with the modern A/V receiver. I cannot tell by looking at the picture of the rear of this receiver how many of these pieces I could connect. Or is there possibly a switch box I can connect once to the receiver and 3 or 4 devices to switch between? Or some sort of conversion gizmo that transitions from the RCA jacks to HDMI? I currently have a Sony 5.2 receiver that, like me, is getting older and not working so well anymore and would like to get a 7.2 before my hearing is totally gone. I do have a HDTV with 3D capabilities and a nice Blu-ray player, so not all is lost. Thank you for any input you can offer.

I want to buy a mid or high end receiver for my 5.2 home theater system, I don't know whether this is a good match or not.
