The iU2 by Tascam is a pocket-sized, ultra-lightweight (7.76 oz) audio/MIDI interface for iPhone, iPad and iPod touch. Not only is it compatible with most any iOS device, it also works with both Mac and Windows computers. It provides zero-latency monitoring allowing you to simultaneously hear yourself and record without delay. It also comes equipped with MIDI in and out for synths, drum machines and other MIDI devices plus a digital output for connection with digital mixers or recorders.
The iU2 features two 1/4" microphone inputs and includes a 1/4" to XLR adapter for connection with most any phantom powered condenser microphones. The inputs also accept line-level signals for guitar and bass recording. Both inputs are amplified with a built-in preamp and pass through an onboard analog to digital converter for enhanced sound with low noise, delivering true stereo recording.
