The Dayton Audio IMM-6 is a professional-quality measurement and recording microphone that is designed to work with the entire suite of Apple "iDevices" iPad, iPhone, and iPod. The rugged construction and compact size make it the perfect companion for audio professionals who must work on-location performing acoustic analysis, monitoring audio levels, or recording. Each IMM-6 is individually hand-calibrated using a laboratory-standard measurement microphone, for consistent, repeatable measurements that match the level of precision previously offered only by expensive stand-alone microphones.
