The iMic USB Audio Interface from Griffin Technology allows you to connect microphones and other input devices to your iBook, PowerBook, PowerMac or other Mac or PC system using a USB interface. It supports both mic and line level inputs via a selectable switch, and provides line-level output for connecting speakers or headphones.
The iMic is also useful for converting vinyl LP and tape collections to MP3s and CDs using a turntable or tape deck as well as the downloadable Final Vinyl (for Mac users) or the software of your choice. Additionally, the iMic is great for home studio recording and podcasting and is compatible with modern hardware like GarageBand, iMovie, and Final Cut Pro.
