Old sound system to new Blue Ray?

[OrSelkie]

I have an older Bose surround sound system with 2 RCA plugs. My new Blue Ray will only take coaxial cable. Is a splitter all that I need or do I need either an audio converter decoder or an optical reader cable?

If your Blue Ray has coax digital audio out you need a DAC to connect it the the Bose. This one works with 5.1 which many don't.
