Question about shielded wire...

6L6 · 5th January 2011, 01:38 PM

I have a good amount of a 2-conductor wire in a braided shield. Not coax.

2 individually insulated stranded conductors of about 20AWG in a braided shield, with a layer of insulation on top of that.

When using this for single-ended line-level connections, what do you do with the shield?

I see a number of possibilities -

1. Ignore the shield and don't hook it up to anything.

2. Connect the shield to ground on both ends

3. Connect the shield to ground on one end.

4. Connect both of the internal conductors to positive, and have the shield as ground.

What would be the most common way of hooking up an internal connection with a wire like this - for example an RCA female to a selector switch to a volume pot, to the circuit.

I have not used this type of wire for internal connections before. I have used it for interconnects, having + and ground on their respective internal conductors and the shield connected to ground on one side.

Hi,
use the two cores as flow and return.
Connect the shield at one end only, probably the send/transmit end.

Wonderful!

Gentlemen, thank you.

Either 3 or 4, with a slight preference for 3 - i.e. I agree with the others.
