Default 4-pin XLR connectors???? what for?

I was in an electronics supply store the other day getting some parts for my own ideas that I build, and the guy asked me if I wanted the new 4-pin XLR connectors.

I said FOUR pin connectors??

He said "all the new equipment is coming out with it now"

I asked, like what? what is the 4th pin for, extra shielding? some new implementation for more noise cancellation?

He couldn't answer at all. And I have never seen these connectors on any gear ever before....even new gear I would like to consider myself familiar with.

Am I just in the dark here and everybody already knows about these 4-pin XLRs?

Someone please teach a man to fish here.

4 and 5 pin are very common for power (4 pin: field recording power A & V, GML uses 5 pin for there power interconnect)
6 and 7 are common on power and signal cables (I believe Sound Deluxe uses 7 pin for there tube mics)

4 pin typically 12VDC on XLR.
"All the new equipment"? huh?
Dude was giving you some bunk.

yeah, thats pretty good. the "new connectors." they aren't new. we're putting them to use as a small 1 channel more me headphone system.

I think I'd stay away from that store if thats the information they're giving out.

My Neutrik catalog shows seven pins as the max on a standard XLR. As stated, four pin is used for power on cameras and VTRs, usually pin 1 minus and pin 4 plus for DC. The audio output of many HD camcorders is a five-pin XLR for stereo audio.

The guy didn't know what he was talking about. No equipment is using 4-pin for "regular" audio. It would make more sense to use 5-pin for stereo.

And there you have it.
Some one sold him their entire inventory by using that story now he is trying to get rid of them the same way.
