Hey all!

I want to make a pair of ~10ft interconnects to hook my pre-amp to my monoblocks. The cable I bought is belden 82259 : https://edeskv2.belden.com/Products/#s=82259&r=0, and some neutrik 352g male rca plugs.

The cable has some braided copper shielding around the main wire, which I will use as the ground channel. The thing is that I have no idea how to solder the shield to the plug. Can anyone tell me how I should do that?

I usually un-braid the shield back about as far as I've stripped the wire, then twist it. Then it's just like soldering another wire.

lots of flux, problem solved

Or a solder pot. The hard part is tinning it. Soldering is easy.

Twist it, tin it, solder. Easy as that.

Oh, you might want to cut off a little of the braid or the ground will be way too thick to solder properly.

Never use a shield as a ground channel, it becomes an antennae.

 

[papomaster]

Why is that? If I understand correctly, the shield cancels the RFI by creating its own magnetic field.

What if the shield is soldered at one end and not the other?
will reduce the "antenna" issue?

What's the difference between a shield and a cable to act as a ground channel ? (as long as it's connected to a chassis or something similar)

 

[grawk]

yes, just connect the shield at one end, and you avoid the antenna problem.

 

[freakydrew]

at the end where you will be soldering both, make sure the braid/ground does not touch the main wire as it may short this out (I just found this out the hard way)

With a coaxial cable you have to use the shield as ground, and connect it on both ends.

Next time get shielded twisted pair. Or quad cables. And run your interconnects balanced with floating 10K:600 ---> 10K:10K transformers. Make noise pickup & ground loops call you daddy.

"Whos your daddy?"
Hum: You are...
"damn straight, now **** and get back out there on the corner."

QFT, glad to see you set the record straight.

What about wrapping a piece of solid bare wire around the shield at the end and soldering all around?
