Product Description:

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 (with 3.5 mm jack). 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.

The IMM-6 uses an omnidirectional electret condenser capsule that allows for a single calibration file for high-precision measurements so you can measure the output of a speaker driver, or the response of a whole room!

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 and include a sturdy carrying case with foam insert.

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). Visit the Dayton Audio calibration download tool, where you will be prompted to enter the serial number from the case of your iMM-6. After entering the serial number, your download will start.

Note: In order to use your iMM-6 as a calibrated measurement microphone you may be required to purchase an app for your tablet or smart phone.
