microphone cable building questions
So, here are my questions:
In the cable I'm working with one purple and one clear wire. Which is positive and which is negative? Or does it matter so long as I'm consistent....? Which of the terminals 1, 2 or 3 in a female XLR connector is positive and which is negative? Is the standard 1=G, 2=positive and 3=negative? Which of the terminals in a female 1/4" connector is positive and which is negative? The terminal in the position that corresponds to '1' on the XLR seems to make contact at the ring and '2' at the tip. Is it ring=negative, tip=positive? So would it work out if I designated purple=positive, clear=negative, and then linked the two connectors so that XLR 1--TRS G...XLR 2-- purple--TRS tip....XLR 3--clear-- TRS ring? Thanks! |

Since these are not standard colours for a mic cable, you can choose what you like. Just make sure that the screen braid connects to pin 1, and pins 2 and 3 connect to the same pin number at both ends. d |

I'm sure that I read somewhere on the net that positive electricity flows through lighter colors and negative electricity flows through darker wires. You should disassemble every one of your mic cables, note the colors and which pins they're connected to, and be sure that you don't plug one with a dark color on Pin 2 to one with a light color on Pin 2 or else you'll get no sound. Naw, I'm just pulling your leg - wire is wire. Just use decide which one is positive and which is negative and use that scheme throughout. Which of the terminals 1, 2 or 3 in a female XLR connector is positive and which is negative? Is the standard 1=G, 2=positive and 3=negative? That's correct, but you need to understand what positive and negative mean in the context of a microphone. It's not like a battery since the microphone produces alternating current. A properly wired microphone makes Pin 2 go positive with respect to Pin 3 with a positive pressure on the diaphragm. Positive pressure makes the diaphragem move away from the sound source. Which of the terminals in a female 1/4" connector is positive and which is negative? The most common configuration is with the tip positive with respect to the ring. In other words: Pin 1 = sleeve Pin 2 = tip Pin 3 = ring |

Which of the terminals 1, 2 or 3 in a female XLR connector is positive and which is negative? Is the standard 1=G, 2=positive and 3=negative? Which do you want it to be? There are two standards. Which of the terminals in a female 1/4" connector is positive and which is negative? The terminal in the position that corresponds to '1' on the XLR seems to make contact at the ring and '2' at the tip. Is it ring=negative, tip=positive? For the most part, the tip should be positive when the microphone diaphram is depressed downward. So would it work out if I designated purple=positive, clear=negative, and then linked the two connectors so that XLR 1--TRS G...XLR 2-- purple--TRS tip....XLR 3--clear-- TRS ring? Depends on whether you are in Ampex land where pin 3 is hot or Altec land where pin 2 is hot. Don't worry about it, just be consistent. --scott -- "C'est un Nagra.
