I have a DENON receiver (AVR-1912) and I want to send the sound to a BOSE Cinemate 1SR sound bar. The bar only accepts RCA plugs (in addition to digital or optical) but my receiver only has connectors with speaker wires. I was planning to use the "Zone 2" feature of the receiver but again, only speaker terminals are the only output. Is there such a thing as speaker wire to "red and white" RCA jacks?
