Plugs Directly into the Apple Lightning port

Direct-connect, bypasses all Apple analog electronics using a digital audio link and supplies charging power when the included AC adapter is plugged in.

Powered by the device or external power supply

On the bottom of the microphone is a 1.3mm 5.0VDC power jack input for iOS device charging. A universal voltage AC power adapter is included.

On-board Analog Electronics

A high-resolution analog preamp, regulated low-noise power supply, Analog-Digital Converter (ADC), and Digital-Analog Converter (DAC) are used for precision measurements and audio quality.

Factory Calibrated

Calibration is stored in the microphone for instant accurate SPL readings. Just plug iTestMic2 into your iOS device, launch AudioTools or another Studio Six Digital audio test app, and the calibration is automatically transferred to the app for accurate SPL readings. S6D use a regulated internal power supply, calibration will not change with varying iOS device voltage. No user calibration is required.

At any time, you may use a standard 1/2" nominal calibrator and check or adjust the calibration.

Each iTestMic2 now includes individual frequency calibration files that improve the frequency resolution of the microphone and cancel out any minor capsule deviations.

Analog Output

iTestMic2 includes a 3.5mm (1/8") stereo analog audio output jack for test signals as well as general purpose audio output.

Note that this is a full-level output and does not respond to iOS level controls.

Professional Test & Measurement Microphone

The 1/2" nominal diameter microphone has been designed to minimize high-frequency diffraction effects for the flattest frequency response.

iTestMic2 has 2 gain ranges to support a wide 25-120dBA SPL range.

The microphone capsule and electronics provide an extremely flat response,with low frequency response to 10Hz for accurate measurements below the audible audio range.

Technical Information

The dual-gain range mic preamp, A/D converters, D/A converters and USB digital audio interface are all contained within the mic itself, so no Apple analog electronics are used. This lets us bypass the heavy filtering and compression that are normally in use, and also to store calibration values that are read by software. 

iTestMic2 is equivalent to having a pro Type 2-class test & measurement mic, low-noise matched preamp with two fixed gain ranges, A/D converter, DAC, and USB digital audio interface, all combined in one portable device.

iTestMic2 meets ANSI / ISO Type 2 specifications for frequency response, linearity, and directional characteristics.  S6D do not guarantee that this microphone can meet the strict environmental requirements of Type 2 or Type 1.
