We need eyes and a meter on this much maligned receptacle. Can the OP make contact with the "lighting friend in the banquet room"?

I'm betting this is an actual microphone input since crazy things happen in places like banquet rooms. But there's a slim possibility it's just a 120-volt receptacle earmarked for the portable PA system. The "collective" wants to know...

Mike Sokol

I've seen enough dodgy stuff in hotels and banquet halls that I fully expect this to be a mic input.  And these places seldom spend money on separate electrical service for a system small enough to run on a 15-20 amp circuit.

You guys have it all wrong.  It's an outlet dedicated for Irish use only.  The labeller, unfortunately, was as good a speller as they were racially polite.

A lighting friend sent me this. It was in a banquet room
Mississippi Internal Catering ??
(around here, banquet halls can spell even spell Mic, never mind provide wiring - however bizarre) 
Just because WE see it one way, don't ASSume it means what WE see.

You're driving down the road, and you see a big billboard with one word.  PAIN.
Hmmm. that's odd. Why advertise for pain. Here in Quebec, I see an advert for a bakery.
Pain is French for Bread.

Just sayin...

There is similar nonsense in the photographic world.  Studio flash connections to a camera are usually via a small co-axial connector called a PC sync socket.

It seems to be common practice in the US to extend these cable by cutting them in half and fitting two blade power connectors so they can be extended with standard extension cables.

EDIT:  Having written that, I couldn't find any examples.  I did find this though, which is a slightly safer version of the same thing.  At least a bit of thought has been put into it:

This sort of "I don't know enough about electricity to know where to buy some different connectors, but I know enough to be safe" attitude is scary scary scary.

I've scene this in arenas for NBA basketball. A powerstrip is placed by the base of the nets to all the photographers can plug in, and it goes to some sort of trigger for the strobes in the arena. Kind of crazy.

It is.  XLR connectors would be ideal for this.

It is common practice because it goes WAY back to a time when the flash attachment had a "Edison" socket to connect that cord to.

I have one in my office and here are some pictures from the web.

We don't need to cut the end off a cord, we just walk into any camera store and ask for a PC to household flash cord

To be fair, I've labeled a receptacle "Do not use for audio" before because there were consistent noise issues from light dimmers on that particular circuit.  Maybe that is what is at play here.  Maybe at some point the local tech had noise issues and plugging the "mic" or audio system into a different outlet fixed the problem.

What scares me about the 'PC to household' flash cord is not that the photographer might make a mistake, but that someone else in the vicinity might make a mistake and plug your camera's PC sync socket into 120V power... what will that do to your camera?
