Calibrated measurement microphone with USB plug & play connectivity
miniDSP UMIK-1 Omni-Directional USB Measurement Calibrated Microphone
The miniDSP UMIK-1 is a plug & play measurement microphone from our test and measurement category. This product is developed by miniDSP. This company is specialized in consumer friendly DSP solutions. The UMIK-1 is perfect for acquiring frequency response data for designing speakers, measuring in room response for room correction or home theatre calibration and many more acoustic measurement applications. This product is recommended by Dirac Live to acquire the right data for their Dirac Live Room Correction software.
The microphone is powered through USB and features an intergraded 24-bit ADC. This eliminates the need of a pre-amplifier or soundcard. Thanks to the USB Audio class 1 interface there is driverless support for all major operating systems and acoustic measurement software. Each microphone is supplied with an unique calibration file that ensures a flat frequency response from 20 Hz to 20 kHz.
Each UMIK-1 has a 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 do I use for measurements?
A: We recommend Room EQ Wizard (REW). This free room acoustics analysis software is perfect for measuring and analysing 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-1 with a mobile device?
A: You can connect the UMIK-1 to an iPad or iPhone through a ‘lightning-to-USB-camera-adapter’. The compatibility with Android devices differs from brand to brand.
Q: Can I use the UMIK-1 to measure impedance curves or acquire T/S parameters?
A: The UMIK-1 measures an acoustic signal. Therefor you cannot use the UMIK-1 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 on package.
