Hey all.
When I connect internal DC power or SE input/output I use a drill to twist 2 wires which creates a twisted pair.
What is the best technique for balanced signal (3 wires), or bi-polar PS (3 wires)?
Straightforward options seem like:
1) Twist 2 of the 3 and have the 3rd by alongside independently.
2) Twist all 3 together with same drill technique
3) Braid the 3 ?
What is the best option?
Thanks in advance

Thanks all for the help.
Speedskater, I want to make sure I get this correctly.
For DC, I currently have a twisted pair for +/- and another single wire for GND. Is this OK for DC power, or should I twist all 3?
Based on your post, for balanced signal, the additional wire is meaningless unless its a shield?
Inside the chassis, you might use:
a] For a ± DC power supply, a twisted 3 wire cable.
b] For a balanced interconnect, a Shielded Twisted Pair (STP). The shield might not be necessary. a third wire does not make a shield.
c] For an unbalanced interconnect, a co-ax cable.
