Question about terminology. Is SPDIF the same as Optical Digital Audio Cable? My soundbar says Optical input, while my TV has an SPDIF output (only). Thanks!

The answer is yes and no. S/PDIF refers to digital audio which can be either coax or optical. In practice, SPDIF is often used for coax and TOSLINK for optical. If your TV has an RCA connector (usually orange) then it's coax. There are converters available to go from coax to optical and vice-versa.

Thanks.... I think.

I haven't kept up with all the various types of connections over the years. Been trying to read up on what the heck plugs into what, and it's a bit confusing.

Probably another stupid question but...

If the S/PDIF is the coax variety (i.e., RCA type plug) can I use any RCA type cable into a converter, or does that have to be a special cable? I'm only seeing a 'box' to convert the signal, so that means one cable in, another out to my soundbar.

Oh, and just to confirm... if my soundbar has one of those squarish plastic inserts, that's gonna be the TOSLINK optical variety, yes?

Regular analog RCA cables are not shielded and are subject to interference. A digital audio coax cable is shielded. It's the same coax that's used for other A/V applications. Yes, the converters are "boxes" where one type of digital cable goes in and the other type goes out. The squarish connector is optical (Toslink).
