Shure SM57 & phantom power

[hemmick reef]

Can anyone explain what phantom power does exactly, and does the SM57 need it or will it cause damage to the mic?

Thanks

Hope this helps, phantom won't harm your 57.

Condesnser microphones require power to operate. They could possibly be powered by batteries (unreliable) or external power supplies (bulky and inconvenient). Phantom power was designed as a convenient and universal way for the mic preamp to provide power down the mic cable to condenser mics. Dynamic microphones do not require phantom power and in general, applying phantom to a dynamic will not harm it, unless that dynamic is a ribbon microphone. Ribbons don't like phantom and could be damaged by phantom.

Your sm57 is a dynamic, but not a ribbon. Therefore, sending phantom to your sm57 will not harm it.

So... is the same story with my D112? It´s ok to send +48v phatom to it?

D112, no problem. There are only a few mics you should worry about, all ribbons.

If you had a ribbon, you would probably know it.
