XLR wiring instruction:
Pin1= shields, Pin2= brown (Signal+), Pin3= white (Signal -).
Should space not allow to solder all strands of the many shields, you can put only each a few strands of each layer of the shields to ground Pin 1. Cut away any spare strands from the shields and secure that no loose strands are hanging around. Use a shrinking tube to avoid short ciricuits. We do not recommend to put any ground to the body shell on either side of your XLR line. The connector shell will get to ground once pluged into a recepacle.
Having your shields put on the connectors shell is dangerous! Imaginge, a loose cable can make contact with another loose cable connector having a diffrent ground potential. So the metal connector is conductive and shall not carry your audio ground used on the shieldings of your audio signal. It can interfere with other "grounds" such as video, data of power grounds, which are potentially different! So keep "grounds" seperate!
RCA/Phono/Jack unbalanced wiring:
Many clients use our 2 conductor cable also for unbalanced interconnects. In this case we recommend to only use 1 conductor (brown) for your signal and put all other wires or parts thereof to ground with the shields. This will increase your noise protection! However for unbalanced application we do have our perfect unbalanced wires 1001x, and 1000x.
Unbalanced Stereo & 2 Channels (loop) application:
We actually do not support the idea to use a a 2 conductor cable for stereo unbalanced wiring, however it will be done and can be made with accepable compromise regarding crosstalk and similar. Again all the shields to ground but not to the body shell of your connector. Check our perfect stereo cables 12001/13001 or our conductor shielded Starquad 11301 for real quality stereo wiring!
