I've seen these talked about but only recently have I needed to make some. If anyone has made these could you please point me to the right place? Can I just pop an XLR connector on the end in place of an RCA and use something like JonR's or ChrisVH's recipes? Who makes really good XLR connectors?Many thanks,
Shawn Harvey
Neutrik (gold-plated) and Switchcraft (silver, then gold-plated) arte the best XLR plugs/connectors.Use one of the commercial twisted pairs as outlined in my DIY note, OR use a homemade twisated pair.
Most true balanced connections don't need a gorund connect, but for those that do, a 16 gauge stranded tinned coipper wire on the out side of either a commecial twisted pair, OR on the outside of a homemade twisted pair will fill the need from pin 1 to pin 1)
The other connections are: one of the twisted pairs for connecting pin 2 to pin 2, and the other for pin 3 to pin 3. Outer briad connected to the shell ground at the ssource only,, and the pin 1 to pin 1 wire (if needed) outside of this.

John,Thank you. I'll probably try to make a set of balanced cables with your latest DIY recipe in a few weeks and post results here.
If I understand what you are saying, the method for balanced cables is basically like that for RCA/unbalanced and I probably don't need a shield with balanced interconnects. I can pretty much leave pin 1 alone on both ends and just use the regular-recipe twisted pair unless I run into problems with noise, yes?
Assuming a shielded interconnect, the rule of connecting to the source end is the same as with RCA's.
Did I get the message correct?
Shawn
Mostly.I would still use a shield over the twisted pair, just spaced away from them. True balanced operation is affected less by the shield copmpared to single ended.
What I was trying to convey was that three wires are often not needed, and if the 3rd wire is needed due to minute differences in chassis potentials that need equalizing, then a third wire outside the shield, away from the twisited pair will do nicely, and avoid contaminating the pair with any ground currents/noises.
