RCA and Coaxial Audio

[ripineros]

Hi everyone, I'm new to this forums, I have been checking them for a while but I just decided to register.

I have a doubt regarding a setup. I own a kinda old receiver that only has 1 coax audio input, now, I have read that both, coaxial audio and rca video cables work at 75 ohm and thing is that I also own a basic RCA A/V switch with 3 inputs and 1 output, so the question is, if I connect a coax audio cable from any source to one of the 3 video inputs and then using another coax cable I connect the switch from its video output to the receiver coax audio input would I still get 5.1 audio at descent quality?.

Thanks for the help!

It's worth a shot.

I'd say you haver a good chance of success. The good thing about digital is that it generally works great or not at all.

Since you seem to have all the needed equipment, give it a go. You won't harm anything.

i have been using whatever RCA cables i own no matter if they say "video" etc on them for any form of input, it has never made a difference, they are all the same cable.

Yes, it'll be absolutely fine. There's no physical difference between a 75 ohm coaxial video switch and a 75 ohm coaxial audio switch. What's more, the required bandwidth for SPDIF is so small that even if it's all badly matched, chances are it'll work just fine anyway, especially if the runs are short.

im currently using an extra skinny cheapo cable that came with my dvd player designed for analog audio transfer to send digital audio and it works so i doubt the cable really matters for it.

As long as the cable meets the 75 Ohm video spec, it will work for digital audio - coaxial digital cable is nothing special and you can use the two interchangeably. There are analog cables that are not 75 Ohms cables and these can cause audio dropouts, though I haven't heard anyone have this particular issue in many years. I am pretty sure Kurt knows what he is talking about since he IS Bluejeans Cable
