I hear it a lot, especially around here. What is it and what does it do for the musician?
Thanks!

It powers things connected to XLR thru the third pin usually with up to 48V.
Things like DI boxes, condenser mics, etc. Usually this is talking about mixers.
EDIT: not ribbon mics, see post #6

yep, that's pretty much it, i don't have much to add. many mics that use phantom power can also run off a battery, but if you have phantom power it's best to go with it instead of a battery.
also, be aware mics running on phantom power are a potential shock hazard. i vaguely remember hearing of a baptist pastor who was electrocuted by a mic running on phantom power when the mic made contact with some water during a baptism. maybe one of our baptist members remembers the story better than i.

And when you look at a mic cable the bottom hole is were the phantom power comes from. its basically activating that when you turn it on on the board.

Oh,
That was University Baptist Church in Waco, TX. Thats the church that David Crowder helped start. It was very sad.

Except for the Royer SF-24 and R-122 I don't know of any ribbon mics that use phantom power. In fact, there is a risk of destroying the element in a ribbon mic with phantom, but only if the cable is wired wrong, or if you have the mic patched into a TRS patchbay, and you re-patch while phantom is hot, or if you hook up the mic directly with a regular mic cable while the phantom is hot, there is some risk as well.
Obviously it's best to just leave phantom off when using ribbon mics, it's just a good idea!
I only wanted to point this out in case someone gleaned potentially costly mis-information from your post!

Ooh... did not know that. I only wish I had much experience with ribbon mics. ;)
Bad grounding in the house is also a huge concern for mic shock hazards. It's always good to check the grounding in the house.
