What cables to own RCA wires

Hello
planning to make short RCA signal cables for a DJ console.
I have little space in the case, so the power cables run close to the signal ones, in addition I have 110V players and there is also a converter in the case.

Therefore, it needs cables with the best possible shielding - length 0.7 and 0.5 m. They can be single, or double.

I am thinking of two wires, the Bitner LP0209 microphone.

I would use it in such a way that the red wire is plus the signal, the white wire is ground, and the screen on one side is connected to ground.

Second cable:

no data, not found anywhere,

instrumental-cable-ins101-double-shielded

I would give the signal through the signal wire, ground with the first shield and the outer shield to ground.

1 cable has any technical specifications, quite good.
The second one has nothing to do but has double shielding, which can give a better effect in such an electromagnetic brothel.

What do you think about it?

Not to ground, but from the signal receiver side also to ground.
Note that not all devices are grounded at the same potential as ground. Sometimes it is not connected at all, sometimes only through a capacitor or RCD bridge. This prevents disturbance of the ground loop.
However, such a solution is a good idea.

That you are slowly making voodo audio. A decent cable around PLN 4-6 / m with a single shield will give good enough results.

I think connecting the screen to ground is better than connecting it to ground because the muck does not enter the mass, but the ground - directly to the pin.
This is what I have been able to deduce from many contradictory sources and a small dose of logic.

RCA plug has 2 connectors. How do you want to pull up the second shield to ground (third potential)?

Not aesthetically pleasing - lead the cable from the screen so that the screen does not short-circuit the ground of the plug and lead the cable to the ground: v
Such a plan came to my mind, I do not know how justified it is, I read that if it is possible to ground it better than to ground it, but I do not know how much truth in it :D

Which cable will be better? The one with 2 wires or the one with 2 screens?

For my taste, you won't hear the difference.

The cable should be flexible and durable. With RCA, there is no need for two wires; one in a good screen is enough. All the rest of the little things you have to decide on your own - depending on the type of plug, for example; you have to choose the outer diameter of the cable - that it can be soldered and that it fits in the opening for the cable exit from the plug.

And I will also ask about plugs - it is better to use only soldered or screw clamped on a wire and additionally solder it? It seems logically that then the connection resistance will be the lowest. I guess it's better gold-plated because they will oxidize less?

I found one more from RedMusic with specifications:

Building:
Conductors: a flexible copper strand of class 5 according to PN-EN 60228 (16 × 0.20mm construction);

2nd layer: foamed PE plastic - white color
3rd layer: special semi-conductive PVC blend - black color;
Screen: braid made of copper strands (160 x 0.1mm construction)
Outer sheath: special modified PVC blend
Coating color: matte black, UV resistant

Outer diameter: 7mm

The lowest resistance will always be in the solder connection. If you have screws, you either screw or solder. Why do both? To make it harder to correct something if you make a mistake?

Another cable that is good but TOO GOOD for your application. I wrote - the most important thing is that it should be flexible and have a good screen. You're not going to drive a tank after that, or pull 100 meters of cable to connect the console to the mixer or something else?
In practice, the cable should be just as long as needed - plus any spare for other equipment setup. A plug, whether it is "gold-plated" (because this coating has little in common with gold), chrome-plated or covered with some other metal - is only a matter of aesthetics and stretching lay people to unnecessary expenses. Not only that - I used to have to solder such a "gold-plated" RCA on a cable and what turned out? That the coating peels off Mrs. Jadzia's dirty claw like a bad varnish ...) ).
In my equipment I have several dozen cables of different types and with different plugs - I did not notice ANY difference in sound - one condition: the plugs and the cables must be durable and solidly made. And will you give gold-plated plugs and cables for PLN 100 for half a meter - it does not matter - apart from the awareness that you have loaded a lot of money into something that is not necessary.

Amen.

This is what it is like when you read about gold, unidirectional wires for hundreds of pounds ... Fortunately, the electrons do not know whether they are flowing through the gold plug or through the chrome one.

If the cables are connected in the case, they will stay there for several years, so mainly the question of shielding remains. Braid + foil? Two braids? Or maybe some other type of shielding will be best for such applications?
Now I have got the power cords, cut them to size and there are fewer of them, but when I do something more specific, I prefer to do it as best as I can.

PS. I am not one of those who pay attention to gold in plugs, I just asked for your opinion: p

If shielding is important, then an instrumental or guitar cable is the best choice because it usually has the best shield. Semi-conductive material reduces microphonics, but this is unlikely to be a problem here. It only has to fit into the plug

Only that in this cable I would have to let go of the screen, because there is no other wire, that's probably a small flaw.

Use the microphone cord and the subject off your head. It's a waste of time for doctorates.

Looks like I will.
Well, more plugs - invest in something better, will there be no difference between them and ordinary nickel or "gold-plated" ones:

plug-rca-cinch-hi-end-reds-music-gold-rca - they look quite solid

plug-cinch-rca-metal - cheap and a lot haha

Pay attention to the solid construction of the plug itself and the certainty of the cable coming out of it. It would be good to have a plug with the so-called strain relief.

A very slight flaw. Opinions on the principle of operation and advantages of "directional" cables are at least divided

THEY LOOK - and the appearance is the least important here. The design of the plug itself is important - and you will not see this outside.
Cheap materials are used in cheap plugs - the thin plates that are to hold the wire when bent are too thin and it cannot be done well. Poor quality plastic insulating spacers melt during soldering, and melted plastic loosens the crimped contacts.
But even the weakest quality plug, when it is well soldered (you have to know it, unfortunately ...) and earned, will fulfill its task better than even the most expensive one with a cosmic look and a price in dozens of zlotys. Remember that the influence of external interference is the more audible the smaller the signal you send via the cable - in your case the signals are large - at the level of volts, hundreds of millivolts, so even if something gets into the signal, you will not hear it, and even measure it. it is difficult, because the value of the voltage induced in the cable also depends on the internal resistance of the connected devices, which in this case is relatively small.
You have read too much (often without going into the context or just nonsense) and without understanding the essential details you focus on what is the least important.

For example. I had a jack from a reputable American company that gave a 25-year warranty on its components. Type as in the link:

http://www.tme.eu/html/gfx/ramka_768.jpg

It looked just like common in our electronics stores. However, I was not able to bend these contact plates with my fingers in any way. Just a solid job. Anyway, this manufacturer has just conquered the market with solidity, he made such contact elements that he has long-term contracts with the military.
