type 1 ios test and measurement microphone
iprecisionmic - AudioControl Industrial (AudioControl)
iPrecisionMic is the only Type 1 certified microphone that is also an iOS direct-connect Lightning accessory. iPrecisionMic is factory calibrated to +/-0.1dB using a NIST traceable pressure-compensated calibrator. The calibration offsets are store in the microphone's nonvolatile memory, and are transferred automatically to an iOS device running our AudioTools app.
