how to st up my klipsch R-4B

I can't find analog audio outs on that TV (just inputs) but it has a coax digital audio output. Klipsch has an optical input in that picture.
You can use a coax to optical digital audio converter. You can't use an optical to coax converter. They don't work in both directions.


You have RCA right and left outputs that will go straight into the respective inputs on the Klipsch R-4B
