Help.. I think my XLR cable is wired wrong?

Recommended Posts

Posted · Original PosterOP

Hey guys, so im setting up a gaming PC and got a condenser mic/phantom power etc. It sounds like absolute garbage. Extremely quiet, and trying to boost it at all just produces a ton of noise. I've done all the troubleshooting, watched youtube videos of the same mic, and I know something isn't adding up.

 

So i opened up my XLR cable to test it with a volt meter/ohm meter... and I think the cable is wired wrong? It was a cheap cable on amazon. Probably from china. This is a photo of the female end, that plugs into the mic.

Using my volt meter, if i touch the negative to Pin #1, I can touch the positive to either Pin #2 OR #3, and both give me 48v and around 35-50ohms resistance. Shouldn't only one of those pins be delivering power? The wiring diagrams I've found online say #2 should be Positive and #3 should be negative, and #1 is ground.

 

With everything going on in the world right now i'd rather not go out and by a new cable... lol I can just re-solder this one. I just need a second opinion. Thanks!!!
 

(PS the pins are labeled thats how i know which is 1, 2 and 3)

Quick question, is this a XLR to 3.5mm jack or an XLR male to XLR female? Because if it is just an XLR to 3.5 then I would assume this isnt being connected to a usb interface which provides the phantom power.
