AUDIOTRAK ATM-10i High Sensitivity Microphone

For iPhones and iPads, there is one killing problem: when trying to calibrate it @ 114dB, it achieves to have the iPhone bug ! Compelled to unplug then plug it again otherwise it's as if there was no more audio.Of course only few people will try to calibrate it but this situation may happen in real life.Maybe it works better on other devices...
