I found this interconnect coaxial cable http://www.cs1.net/products/canare/LV-77S_digital_audio.htm . They said this cable was made without soldering by a special tool, anyone know how to DIY this cable ?

As an electrical engineer, I am going to go and say this is crap. Its not that hard to design 75ohm transmission lines. Instead of solder, they are crimping. They are doing it quickly and with a considerable amount of force. Probably a specialized hydraulic crimp. I would have to look up pressure tables, but you could build a jig with a hydraulic press and crimp at 10 tons or something and get a very tight seal.

i would like to recable my DT770 Pro 250 Ohms but i don't know what type of wire/cable and what gauge i need to use?

i'm thinking to do 4 conductors TRS so in the future i can switch it to XLR.

thanks....

Now i know how it made, impossible for homemade :biggrin:. Well, i'll back to tradtional way.

Seriously... A 10 ton hydraulic crimp press, possibly at the factory in china where they schiit them out by the 1000's... :rolleyes:

Not Impossible at all I use these things everyday, the only thing they have is customized ends and boots to make theirs look nice... :D

 

Here is the tool used to crimp the ends on:

The RCA's:

The BNC's:

And these are Water Tight Fittings that do not require any special skill or gear besides the crimper to assemble, well maybe a little coax. :D

Is there a difference between crimping and soldering? Which is prefferred?

Crimping is mostly used for coaxial cable and 25/50 pair bundles as it is less time consuming than soldering.

 

Soldering will give you the best connection if done properly.

I can imagine the script :  cut off the jacket, pull back all braided wire, put cable in the connectors and put in the tool and "click" :D. I wonder how Water tight Fittings work ? 

Oh, 1 more thing, how to make them look nice ;)

Nope you trim 3/8" off the end down to the center conductor, then back another 3/8" off the jacket to expose the braid, slide it into the fitting all the way and then crimp.

30 seconds to make. 

 

They have a rubber seal that gets compressed around the wire when it's crimped.

 

How to make them look nice...

Buy the ones from the link you posted earlier.

I ordered a foot of Plussoundaudio's new wire thats coming out, I'll let you guys know how it is and post some pictures of it.

post #462 of 2561

usually type 1 paracord can fit up to how many AWG? Cant decide to get either plus sound UP-OCC copper or DHC Nucleotide...both same price but plus = 26AWG while DHC = 24AWG

What new wire? Silver or copper? According to its web site, the pure silver is on pre order and the silver/gold is sold out.

It can take a max of 2mm outer diameter, although practically, I wouldn't go over 1.7mm as it gets even tougher and tedious to sleeve.  The 24awg DHC goes in well and is the wire I started with.
