Connecting SPDIF Output on Sound Card to COAXIAL Input on Receiver—Is It Possible?

what is the difference between these inputs
in the music card I have SPDIF and in the receiver COAXIAL, optical and chinch
how to combine it
Regards

SPDIF
A digital connector standard developed by Sony and Philips that is popular in audio equipment. Thanks to it, data between devices that record sound digitally can be sent without the need for conversion to analog form, which ensures high quality of the signal. Typically, the SPDIF connector is in the form of an RCA type socket.
you have the answer.. at your fingertips
Good luck

you take the cable that you have surely used so far - 2Chinch---stereo mini jack. You plug the sound card into the SPDIF socket - you turn on the digital output in its settings. And one of the Chinchas will be a digital signal that you connect to the receiver (Coaxial) - nothing will happen if you mistake the Chincha.

in the receiver you also need to turn on this input and how it is different in different equipment! [sometimes auto-detects]

that was exactly the answer I was looking for
I now have a regular chinch connected but I also borrowed a special cable from an American audioquest company and I'll see what the difference is - maybe I'll squeeze something else out of my vsx-D814
thanks for the replies and best regards

detected everything and it's ok, only this cable from my friend is too short
I don't want to deal with boxes

SPDIF COAXIAL is a 75 ohm connection like a TV antenna. Just buy some antenna cable and two cinch plugs. On ordinary shielded cable, it will also work if it can be better ...

Hello
so why these expensive coaxial cables for several hundred zlotys if a simple chinch is enough, or as irek2 says a piece of ajzola antenna and two chinches for a total of 3 zlotys, and the difference between the signal for 180 zlotys and the one for 3 zlotys will be so inaudible to our ears. This is probably the propaganda of large corporations to make money on the so-called. audiophiles.
After connecting with coaxial (mine cost PLN 15 - chinche The noise in the speakers has really diminished. I checked them so that finally a flashing inscription appeared on my pioneerek - OVERLOAD and turned off - I turned it on after a while (much quieter) and it was ok.
Hello everyone and thanks for the interview
