Overview

Dayton Audio iMM-6C Calibrated USB-C Measurement Microphone for Apple/ Android

Dayton Audio IMM-6C USB-C Measurement Microphone for Tablets IPhone IPad and Android

Turn any phone or tablet with a USB-C jack into a laboratory grade audio measurement device with Dayton Audio's iMM-6C USB-C calibrated measurement microphone. Each iMM-6C 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.

Applications

The Dayton Audio iMM-6C is a microphone specifically engineered for professional-grade measurement and recording purposes. It is optimized to seamlessly connect to any device with a USB-C port including Apple, Android, and Windows based products. Its durable construction and compact design make it an ideal companion for audio professionals who need to conduct on-location tasks such as acoustic analysis, audio level monitoring, and recording.

Each iMM-6C microphone undergoes individual calibration using laboratory-standard measurement microphones. This painstaking calibration process ensures consistent and repeatable measurements, providing the same level of precision that was previously only attainable with expensive standalone microphones.

A unique serialized calibration file is available for each iMM-6C. This calibration file can be used by most audio-analysis apps for Android, Apple, and Windows based devices that support microphone calibration.

Designed for Mobility

Built into the IMM-6C is the CM6542 ADC/DAC which accurately converts the acoustic information into bit-perfect data for use with any acoustic measurement software that supports external equipment. with a THD+N rating of 0.001%, the ADC works transparently providing maximum accuracy from input to output. The output jack of the IMM-6C allows you to play sweeps and noise from your host device for an all-in-one testing setup, and acts as a convenient kick-stand to keep your microphone off any surfaces your device rests on.

The USB end of the IMM-6C has been slimmed down and extended for guaranteed fit through large phone and tablet cases for no fuss connections.

Omnidirectional Microphone Capsule

The omnidirectional polar pattern of a microphone, such as the IMM-6C, offers a wide range of benefits and capabilities. By using an omnidirectional electret condenser capsule, this microphone is designed to capture sound equally from all directions. Whether you're assessing the acoustics of a concert hall, a recording studio, or a home theater, this microphone can accurately capture the spatial characteristics and reverberation within the space. When it comes to measuring the output of a speaker driver, an omnidirectional microphone ensures that you capture the sound emitted from all angles. This provides a comprehensive representation of the speaker's performance, enabling you to analyze its frequency response, distortion levels, and other important characteristics.

Note: In order to use your iMM-6C as a calibrated measurement microphone you may be required to purchase an app for your tablet or smart phone. Dayton Audio suggests AudioTool for Android and Audiotools for IOS

Help for Android and iPhone users:

There are many applications in the market that provide users with audio measurement software. We do not recommend any specific apps, however, in an attempt to assist the new user of an iMM-6, we have listed links and some helpful pointers below. One for the iDevice/iPhone platform and the other for Android devices.

Android - AudioTool from JJBunn

Here is the procedure for loading the iMM-6 calibration file into AudioTool on an Android device:

  • 1)  Visit the Dayton Audio Calibration File Download Tool on your web browser: Dayton Audio Calibration Download Tool.
  • 2)  Find your iMM-6C serial number on the back of your iMM-6C Case.
  • 3)  Select "iMM-6" microphone, enter the serial number, and press search. Download and save the calibration file by clicking on it.
  • 4)  Open the AudioTool app on your device. Open the Menu at the bottom of the screen and select "Use 1/3 Octave Calibration" to ensure you have the 1/3 octave calibration method selected (if "Use 1/3 Octave Calibration" is not shown in the menu then it is already selected).
  • 5)  Open the Menu at the bottom of the screen, and select "Import Cal File". You will be shown the Android file browser.
  • 6)  Locate the iMM-6 calibration file you downloaded in step 3, and click on it. This will import a copy of the calibration file into the AudioTool directory (there is no need to rename the file to .cal, or make any other changes).
  • 7)  Open the Menu at the bottom of the screen again and select "Load Cal".
  • 8)  Select your calibration file (for example: CMM10000).
  • 9)  The calibration data will be loaded and summed to the 1/3 octave bins used by AudioTool, and saved in your Preferences - there is no further need to load the file whenever you start AudioTool, unless you change the calibration method or microphone.


iPhone - AudioTools from Studio Six Digital

Here is the procedure for loading the iMM-6 calibration file into Audio Tools on an iPhone:

  • 1)  Visit the Dayton Audio Calibration File Download Tool on your iOS device: Dayton Audio Calibration Download Tool.
  • 2)  Find your iMM-6C serial number as pictured (on the back of your iMM-6C case).
  • 3)  Select "iMM-6" microphone, enter the serial number, and press search. Download and save the calibration file by clicking on it.
  • 4)  Open the "AudioTools" App.
  • 5)  Open the "Microphone Setup" Menu.
  • 6)  Make sure your iMM-6 is now connected to your device. It will say "Headset Mic 1" when connected. If it says "Internal Mic 1", your iMM-6C is not connected.
  • 7)  Press the (i) button to the right of your screen.
  • 8)  Press the "Calibration File" button labeled in blue.
  • 9)  Press "Import" at the bottom of the screen. You will then see the file you just downloaded. Click on it.
  • 10)  It will now show up in your list of calibration files. Click on it and then press import at the bottom of the screen.
  • 11)  The calibration is now installed in the "Sound Tools" app!
