balanced audio cables
alright.
here's what i need:
2x 20 meters of balanced audio cable going from my future mixer to my future sound card, most likely with TRS connectors, not XLR.
and here's my problem:
this kind of cable can't be found anywhere, so i'd have to make it myself (no problems there as i can solder just fine).
but what kind of cable should i buy? is microphone cable good for line level signals? i've been looking at 2x0,22 mm^2 cables. but i'm not sure if they all have the metal shielding on them where you apparently connect the ground on the connectors. i've bee googling this for over a week now and i just can't figure it out.
would this cable work for me: http://www.thomann.de/fi/cordial_cmk_222_sw.htm ?
i have no idea if it has the shielding where to connect the ground or not and i can't find any details about it by googling either.
also is this the only kind of cable what i should be looking for? 2x0,22 mm^2 microphone cable with the two signal wires twisted around each other with the metal shielding on it or would some other kind of cable work better?
currently i have rca cables running from my bedroom to my living room where the computer is and the background noise is fucking killing it, that's why i'm thinking of getting these balanced cables.
i figured i'd post this here instead of the production studio because this has to do with djing and not producing, even though i think there might be more people who know about this kind of stuff in the production studio.

you possibly could just order balanced audio cables from some online dealership. im sure the cost of the cables + shipping is worth the hassle of trying to make your own

i would do that if such cables were available somewhere at a decent price, but i haven't found any anywhere!

if its easy as fuck...why are you asking questions???
i would assume easy things means no help...kind of like cleaning your sink...its easy...so do you really need to ask people how to clean it?

oh FFS. are you stupid or something? making the cable is easy as fuck. but i'm not entirely sure on what kind of wire i should be getting or what would be best for this kind of a solution, so i thought i'd ask here where i think at least someone would know seeing as this is the dj booth and many dj mixers have balanced outputs. but apparently everyone connects their expensive gear to some crap 50€ stereo and/or integrated crap sound card or some 5€ soundblaster with rca inputs or worse yet, just a 3,5mm miniplug.

not everybody connects their equipment to a cheap little stereo...i certainly dont...but do you really need super expensive cables for home applications? probably not...go get yourself some monster or mogami cables and be happy

theoretically all you need is a cable with 3 wires in it and a TRS on each end. the cable in the link you posted WILL NOT WORK for balanced audio. that cable would only be good for an unblanced connection. before you go to all the trouble you should make certain that your mixer has balanced outputs, most interfaces have balanced inputs but will also accept an unbalanced signal.
you will want to use a shielded cable since 20 m is probably long enough to pick up some electromagnetic interference. im not sure, because i dont know too much about them, but you may need a direct box in your signal chain as well. this may be the reason you cant find the necessary length. just an idea and like i said, i dont know much about direct boxes. i just know that they are sometimes required for running audio cables at longer lengths.
if all else fails, just move your computer and booth closer together.

Balanced cable
If you want to make a balanced cable you need to make sure your mixer has balanced outs TRS, or XLR. You also want to make sure that the input you are going into is balanced as well. Both ends of the connection have to be balanced for you to get the noise regection that a balanced conection provides. Simply using a shielded cable does not insure a quite connection.
The cable you linked looks like it will work provided it has a shield. You would connect that to the body of your connector.
When making cables on a TRS connectoin
tip +
ring -
sleve ground/cable shield
On an XLR
pin 1 ground
pin 2 +
pin 3 -
Here are some links from the rane website that will give you a good idea of how to go about running audio over such a long distance.
