Hello All, I purchased Viablue NF-S6 cable to make my own XLR cables. This is there top of the line cable. It is very thick and has the following components.
1.Top outer layer 16mm inside tube Inside metal foil sheilding and air tubes all around.
2.Second Layer tube 10mm inside gold foil shields and 3 conflicting strand coil shields.
3. Inside there is a center air tube and 6 white cables and 6 black cables of the same size. Surrounding these are two counter wound wire shielding.

The way I have thought I should wire is. Pin 3 Black 6 strands, Pin 2 White 6 Strands Pin 3 Surrounding mesh.

Does this sound right or should the most external shielding meet with the internal shield to meet at pin 1?

Thanks for the suggestions.

Those are cool looking cables. Are the conductors silver?
There is a lot going on with those. If possible, you should try to find out from the manufacturer how they intended for them to be connected to balanced connectors.
In the absence of a recommendation by the manufacturer, I would try connecting the white wires to pin 2, black wires to pin 3, inner shield to pin 1 at both ends and outer shield to pin 1 at only the source end.
Test continuity before you try and use them.

Contrary to what is said here ground shield (mesh) has to be connected at both ends to pin 1 in a balanced configuration. The ground is only floated in a single ended application. Depending on your application pin 2 will be phase correct pin 3 phase inverted, (or reversed if you application calls for pin 3 hot) and pin 1 ground.

This cable apparently has two shields, an inner shield and outer shield.
If manufacturer recommendations are not available, I suggested connecting the inner shield at both ends to satisfy the ground requirement and connecting the outer shield at the source end only, for shielding.

It depends. The two shields must be electrically isolated. Otherwise, the floated shield will not function properly.

Agree, that is why in my first post I also suggested to "Test continuity before you try and use them."
However, I was just guessing since I have not encountered cable with two shields before, which is why the best approach would be to "find out from the manufacturer how they intended for them to be connected."

I contacted Viablue and got a prompt reply. Seems I wired things correctly. I was supposed to cut out the foil and wired pins 1. Grounding, 2. White, 3 Black. I tested continuity and also short between pins and we īre ok no shorts. All seems fine.

What has me intrigued is when I use my older Ultimate cables the volume of the music rise with respect to my Via blue XLR. Could it be they are too thick and thus there is an increase in resistance?
