SmartRig by Saranomic

XLR Microphone Audio Adapter with Sound Level Control and Phantom Power for iPhone, iPad, iPod, Mac, and Android Smartphones
It was my Microphone audio interface during 2 years...
Unfortunately I lost it.
It comes with a phantom power, so you can plug all kinds of microphones.
Very simple, but works very well...
