Measurement Microphone
Installation Manual
Congratulations...
The AudioControl SA-4100i is a professional-quality,
uniquely-fine, test and measurement microphone made for
the iPod*, iPhone*, and iPad*. With this microphone directly
connected via the Lightning connector to your iOS device, and
our Mobile Tools application loaded, you will be able to analyze
the acoustics of any environment, such as home theaters, cars,
convention centers, comfy living rooms, garden sheds, rowing
boats, the Houses of Parliament, and even rustic Mongolian
yurts. The SA-4100i is designed to be very easy to set up, so
you can quickly measure and view the acoustic spectrum, and
improve and optimize the listening experience for the good of
mankind.
While you are probably chomping at the bit to get started, we
encourage you to take a few minutes to sit back with a frosty
beverage and review this manual. It will probably answer a lot
of questions you may have, and save you some phone calls.

7. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 8. Use only attachments/accessories specified by AudioControl. 9. Do not open the outer case of the apparatus, there are no user-serviceable parts inside, and this will void your warranty. - Page 3 Specifications: • Prime Directive: The SA-4100i shall be a Test and Measurement Microphone for use with iPhone, iPod, iPad • SPL Dynamic Range: 28 dBA to 120 dBA •...

- Page 5 SA-4100i Accessories Your discerning purchase of a fine SA-4100i includes the following items: 1. The SA-4100i microphone with attached cord and Lightning connec- tor. 2. A zippered soft microphone carrying case, much like a pencil case from our school days. Except my friend Neville nicked mine, I am pretty sure.

- Page 7 Notes The following notes may help you get the best out of your equipment. As they are in no particular order of importance, the use of a civil-war era bullet point list has been authorized: • Plug the microphone directly into the iOS device. Do not use any docking connection extension cables as these are not authorized and may not operate or work reliably.

- Page 9 RTA Real Time Analyzer Typical RTA Page This graph shows the Sound Pressure Level measured by the micro- phone across the audio frequency band from 20 Hz to 20 kHz. In this example, the measured response starts to decrease at the higher frequencies.
- Page 10 FFT Fast Fourier Transform Analyzer Typical FFT Graph This FFT graph shows the Sound Pressure Level across the audio fre- quency band 20 Hz to 20 kHz, after the Fast Fourier Transform has been applied mathematically to the microphone measurements. FFT spectrum analysis gives early clues to any audio distortion in the system.
- Page 11 If a pure sine wave was playing at a certain frequency, then the micro- phone would measure this, and the FFT display would show a peak at the fundamental frequency. If however, this pure sinewave was overloading the power amplifiers and causing distortion, then the FFT graph would display the fundamental frequency peak, as well as other (naughtier) peaks at higher harmonic frequencies.
- Page 12 Polarity This menu allows you to analyze the speakers in your system and determine which of them may be wired out of phase compared to the others. For example, the positive and negative speaker cords may be swapped on one speaker, giving rise to an audio cancellation, most noticeable at the lower frequencies.
- Page 13 Typical SPL display -----------------------------------------------13 ----------------------------------------------...
- Page 14 This Mobile Tools menu allows you to analyze and ad- just the front speaker delay and subwoofer delay in your AudioControl DQ61 or DQDX system. The information section displays the details of the front and subwoofer delay adjustment procedures. Information This menu has two main sections: General Information and Microphone Information.

Page 15: Troubleshooting And Maintenance
Troubleshooting and Maintenance Microphone not detected by iOS device: 1. Check the compatibility of the SA-4100i with your iOS device. 2. Check the Lightning connector is fully inserted. 3. Check the cable is in good condition, and has not been nibbled in two by angry woodchucks. - Page 16 4. You cannot let anybody who isn’t: (A) the AudioControl factory; or (B) somebody authorized in writing by AudioControl to service the SA-4100i. If anyone other than (A), or (B) messes with the SA-4100i, that voids your warranty. -----------------------------------------------16 ----------------------------------------------...
