Dayton Audio iMM-6 iDevice Calibrated Microphone 390-810

Overview 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. Dayton Audio's iMM-6 is also compatible with Android and Microsoft devices that use a 3.5 mm TRRS jack. A headphone/line-out is built in for monitoring the recorded signal, and a kickstand elevates and angles the measurement capsule for more direct measurements. Each iMM-6 is ruggedly built with high-quality components. A sturdy carrying case with foam insert is included. A unique serialized calibration file is available for the iMM-6. This calibration file can be used by most audio-analysis apps for the iPad, iPhone, and iPod Touch (see compatibility list for recommendations).
