IK Multimedia has created a solution for integrating any type of microphone with any iOS device, and that solution is the iRig PRE. The iRig PRE gives you ultimate flexibility in mobile recording with your iPhone, iPod touch, or iPad, allowing you to connect any type of microphone from regular stage dynamic types, to professional studio-quality condensers, giving you an extremely wide range of options. 

iRig PRE is the first high-quality microphone preamp designed specifically for iOS devices that allows musicians to use their favorite high-quality stage or studio mics with their iOS device. You simply plug-in your favorite microphone directly into the standard XLR connector of iRig PRE with no need for extra cables or adapters. Its adjustable thumbwheel gain control allows the user to easily make precise level settings.

The onboard 9V battery provides the necessary voltage for phantom-powered studio. Like all other IK Multimedia microphones, it includes 2 free apps: iRig Recorder (an easy-to-use recording/editing app) and VocaLive (an effects processing app for singers). And like the entire range of iRig accessories, it’s highly portable thanks to its pocket-sized form factor for recording anywhere.
