View Full Version : How Do I Splice a (+/-) to a 3 Pin XLR //Phantom Power?

Hello-
I recently purchased a IDX X-3 Lite http://www.idxtek.com/x3.htm Before I bought it, I was told that I would be able to cut the 2-pin end and splice it to a 3 pin xlr which I'm hoping I will be able to power w/ the on camera battery on my dvx100.

I was able to splice it to a cigarette plug whcih is powered by my battery belt- I'm desperately trying to lighten my equipment load- So doing away with the belt and using the phantom power on the camera to power the light would be killer.

What I need, if it's even possible is someone to breakdown how to make this work- When I cut the 2-pin end off of the light I found 2 cables (1 positive & 1 negative). I have a soldering gun, a 3 pin xlr plug ready to be fitted. I just want to make sure each pin is properly soldered to the right cable (positive/negative).

So if anyone has experience down his windy road of cables, soldering irons, xlrs, etc. Please share some of the light of your wisdom....

Many Thanks-

Hmmm... phantom power circuits are designed for devices with really tiny current requirements. I'd be extremely wary of trying to power a light with it.

If you don't understand electronics, or how to use a multimeter, quit while you still can.

You are only going to cost yourself $$$.

XLR phantom power is rated in Milliwatts for the bias current in a microphone. Your light draws 11 watts. That's about 1000 times the capacity of a phantom microphone source.

Once the smoke comes out of the camera, it's very difficult to put back.

Thanks for all your help guys- Luckily no cameras or people were harmed during the experiment...
