Reference measurement microphone with low noise floor, 32-bit ADC with selectable sample rate and unique calibration file.
miniDSP UMIK-2 USB Reference Measurement Microphone
The miniDSP UMIK-2 is a high performance measurement microphone from our test and measurement category. The UMIK-2 is developed by miniDSP as improvement on the popular UMIK-1, one of SoundImports's best selling products.
The UMIK-2 is equipped with a large 13mm microphone capsule for a reduced noise floor and improved distortion performance. The microphone is powered through USB-C and has driverless support on OS X and Linux. MiniDSP developed a custom ASIO driver for easy integration with Microsoft Windows.
The inbuilt ADC, with a 32-bit resolution, converts the measured signal while retaining high quality. The UMIK-2 is recommended by REW (Room Equalisation Wizard) and DiracLive (V3.x and later) for the highest measurement accuracy. The selectable sample rate (44.1 to 192 kHz) allows for easy integration with most other measurement and recording software.
Each UMIK-2 has an unique calibration file. You can download this calibration file from miniDSP with the serial number from your device.
Q: What are the main differences between the UMIK-1 and the UMIK-2?
A: The UMIK-2 is improved on analog, digital and functional aspects compared the UMIK-1. The larger capsule enables better noise and distortion performance. The improved analog performance is preserved by the high quality ADC. The new USB interface allows for easy software controllable settings, such as gain control and sample rate selection.
Q: There are two different calibration files available for download, which one should I use?
A: For measuring a single speaker or a stereo pair, you use the ‘0deg’ calibration file. The capsule should be pointed at the speakers. For measuring a surround system or multichannel application, you use the 90deg calibration file. The capsule should be pointed at the ceiling
Q: What software should I use for measurements?
A: We recommend Room EQ Wizard (REW). This free room acoustics analysis software is perfect for measuring and analyzing room and loudspeaker responses. However, you can use any software that accepts a calibration file. Other examples are: ARTA, Smaart, Fuzzmeasure, and HolmImpulse
Q: Can I use the UMIK-2 to measure impedance curves or acquire T/S parameters?
A: The UMIK-2 measures an acoustic signal. Therefore you cannot use the UMIK-2 for T/S parameters or impedance measurements. The Dayton Audio DATS V3 is a perfect companion for acquiring T/S parameters. The Audiomatica CLIO Pocket 2.1 is a great alternative, that combines both acoustic and electrical signal measurements into one package.
