The UMIK-1 comes with two unique calibration files depending on two types of measurements:
- 0deg: This calibration file is for Stereo and 2.1/2.2 systems. Point the microphone towards the sound source being measured. In the case of a Dirac live measurement, you'll point the microphone to the center point between the 2speakers. This calibration is so called on-axis calibration file.
- 90deg: Point the microphone towards the ceiling. This calibration file is only to be used for surround sound measurement (i.e. audio coming from multiple directions). For multichannel Dirac Live applications (e.g. DDRC-88A/D, 8x12DL), you should always use the 90deg file.
