The improved analog performance is preserved by the high quality ADC. The larger capsule enables better noise and distortion performance. Q: What are the main differences between the UMIK-1 and the UMIK-2?Ī: The UMIK-2 is improved on analog, digital and functional aspects compared the UMIK-1. You can download this calibration file from miniDSP with the serial number from your device. The selectable sample rate (44.1 to 192 kHz) allows for easy integration with most other measurement and recording software.Įach UMIK-2 has an unique calibration file. The UMIK-2 is recommended by REW (Room Equalisation Wizard) and DiracLive (V3.x and later) for the highest measurement accuracy. The inbuilt ADC, with a 32-bit resolution, converts the measured signal while retaining high quality. MiniDSP developed a custom ASIO driver for easy integration with Microsoft Windows. The microphone is powered through USB-C and has driverless support on OS X and Linux. The UMIK-2 is equipped with a large 13mm microphone capsule for a reduced noise floor and improved distortion performance. The UMIK-2 is developed by miniDSP as improvement on the popular UMIK-1 , one of SoundImports’s best selling products. ![]() The miniDSP UMIK-2 is a high performance measurement microphone from our test and measurement category. MiniDSP UMIK-2 USB Reference Measurement Microphone Plug&Play compatibility with REW & Dirac Live. ![]() Custom Windows ASIO drivers and Plug&Play on Linux/Mac OS X.ADC with 32-bit resolution and selectable sample rate between 44.1 and 192 kHz.1/2″ capsule detachable through 60 UNS thread.Unique calibration file for each microphone.Most all low cost reference mics are omni pattern so this won't tell you anything about how the off axis response colors the sound.Reference measurement microphone with low noise floor, 32-bit ADC with selectable sample rate and unique calibration file. There are a few good reference mics that won't break the bank. If you use a reference mic with flat response, you can even get an approximate true frequency response. After making the measurements you can at least say that the tested mic is brighter, bassier, mid-rangier or chocolatier than a Golden Ears Opus VIII microphone. All you are interested in though is the difference in dB between the mic under test and the reference. Keep in mind the actual response will be very ragged with 10 to 20 dB peaks and valleys. All you are looking for is repeatable results for each run. You should also move the two mics a little and rotate their positions top mic to the bottom, bottom mic to the top or left to right, etc. Making the measurements outdoors can help with this. Ideally you'd also like to eliminate room reflections if the mics are not omni's. Generally, you would match the two mic levels at 1 kHz for each test and then see how much they differ over the audio range. Take the outputs to a stereo sound card and use any of several programs to compare frequency response plotted in dB. You need a little distance from the speaker so the various drivers can produce an integrated sound. Put them several feet from a decent loudspeaker with pink noise at a level high enough to cover ambient noise. ![]() Put them side by side with less than an inch of separation. So given all this, what is a sound-person to do? First find a mic that you really think is top notch with the same pattern as the one you want to test.
