What's the difference between digital coaxial and analog chinch?

Question

You can expand the question because it is like what is the difference between WHITE and BLACK after all, the names themselves indicate the difference ... digital and analog greetings

I know the purpose of the chinche and coaxial cables. I am intrigued by the difference in the construction of these cables, because at first glance they look the same. Is it possible to connect a chinche cable instead of a coaxial because it is cheaper?

PAWEŁ74 · Answer

You can, as long as you don't buy the cheapest crap ... greetings

Pablo1964 · Answer

You can, just like drive a car on baptized fuel. You can also omit the mains plug by inserting 2 wires directly into the socket. It will be worse and in a mess, but not everyone knows the difference. If you want to save on the cable in this way, better buy cheaper equipment. Coming back to the question from the first post - they differ mainly in impedance. The coaxial cable is exactly 75 ohms.

But RCA doesn't have 75 ?, at least usually, so I wouldn't exaggerate if the cable impedance is really that important. I'm not saying it's irrelevant, but if we care about impedance compliance, let's take care of the whole thing. Therefore, I suggest replacing the chinch with the BNC, which fit better when it comes to impedances, but you need to check if it is 75? or 50?, because they are also like that.

Taking this approach, it is better not to buy equipment below PLN 100,000 ... I connected the coaxial with a normal "audio" cinch-cinch cable (1m cable for PLN 35), everything was normal, and Nobel Prize to anyone who would hear the difference after connecting the allegedly special cable to the COAXIAL ...
He writes about a normal cable, not a wire with electrical properties equal to a "wet shoelace" ...

greetings

Pablo1964 · Answer

Coaxial cables have better electrical properties than regular audio cables. The best audio cables are similar to cheaper coaxial cables and have similar properties. However, not all audio cables are shielded and if someone unfamiliar with electronics asks if it is the same and you answer yes - he will buy the cheapest crap (because he asks to save money) and he will surely hear the difference. That is why I believe that we should also be precise in answering laymen.

Quoting my first post ... It clearly says it's not the cheapest cable. Not all cables are shielded? I have never seen a cinch-cinch cable unshielded though the slightest degree, unless you mean speaker cables ... which requires no comment ... greetings

ghost666 · Answer

And I've seen a lot of unshielded cables. Not every rca-rca is shielded, not every coaxial is shielded as well (it's quite twisted, but the braid does not always shield - it depends on how to connect it).

djlj24 · Answer

Flatline cables, which were quite expensive at the time, were not shielded at all. Likewise, Kimbler Cable makes a braided line, not a shielded cable. Few people remember that the screen has one negative property - it increases the capacity of the cable. In the case of digital signal transmission cables (SPDIF) it matters - here you have to look at the matching and wave impedance of 75 Ohm.

The difference is that when I have a DVB decoder connected to the receiver with a good quality chinch audio cable, some channels catch their voice only after the 3rd attempt to switch. No problem with a dedicated digital cable.

PAWEŁ74 · Answer

Then tell me, was I lucky it played ...?
I have SPDIF pulled out on 2 wires from the sound card, the usual two lines. At the end of the cable there is a soldered cinch socket, then a normal cinch-cinch cable to the decoder ... and everything works without any problems.

chaka · Answer

And stereo or 5.1?

PAWEŁ74 · Answer

And so and so. When I play a movie encoded in AC3, for example, in the card parameters I redirect to "SPDIF only", the "DOLBY DIGITAL" diode lights up in the decoder and the sound is 5 + 1. all I need to do is pause it immediately the "DOLBY DIGITAL" signal goes out. So I have no doubts that the signal is decoded correctly, and you can hear it perfectly in movies with a lot of sound effects ...
The same applies to DVD playback.
So I don't understand the ironic

at the end of your speech.

jacek3 · Answer

I had a TV connected to the receiver via a regular chinch. The receiver reacted with a momentary lack of sound to each switching on, no matter what device in the apartment (even opening the refrigerator door). After replacing the chinch with a digital one, the problem is over, so the type of cable matters.
