How could I connect receiver with speaker wire output to streaming device with dual RCA input? - nad receivers nad t765 - love music again

I have a NAD 7220PE stereo receiver that I am my record player, cassette and CD-monitor, and my Airport Express With AirTunes to use. With a view to a stream Sonos ZonePlayer 100 to buy all the audio outputs of these devices around my house, but the ZP100 has only one RCA input and output of the speaker cable, but no speaker wires and the receiver has only one wire speaker output, AFAIK. I thought about, such as audio devices directly to the ZP100, but I want to the recipient, if possible use. If I can, I can connect the speakers with speaker wire to the ZP100, in conjunction with, and access to all my audio equipment from anywhere in my house.

However, I have no idea how to connect the two devices, since I'm no expert of any kind could sound something like the terminals of the port to use RCA cables for speakers from Radio Shack, or have the wrong idea completely?
