The miniDSP UMIK-1 is an omni-directional USB measurement microphone for speaker and room acoustic measurement, recording, and SPL measurement. It is a driverless USB Audio Class 1.0 device recognized by Windows, Mac, and iPad; its interface also supports Linux. With calibration loaded, frequency response is 20 Hz - 20kHz +/-1dB.
Each microphone undergoes three individual factory calibration steps for frequency response and SPL, and has a unique calibration text file linked to its serial number. A 0-degree file is provided for stereo systems such as 2ch Dirac Live or single-speaker measurement; point the microphone at the speakers. For multichannel systems such as 5.1/7.1 or surround setups, use the 90-degree file and point it at the ceiling. The files include on-axis frequency amplitude and sensitivity drift information.
The microphone has a 6mm electret capsule, a 24bit ADC at 48kHz, and a maximum SPL of 133 dB SPL @0dB gain setting at 1% TDH @1kHz. Output noise level at maximum IGPA is -74dBFS. It is USB powered (5V), with a blue LED indicating power, and has a 3/8"-16 clamp thread. The microphone weighs 120gm; the complete kit with accessories weighs 600gm. The connector is miniUSB on v1 / before Jan 2021 and USB Type C on v2 / after Jan 2021.
The box contains 1 x UMIK-1 microphone, 1 x shielded USB cable USB A to USB c (1.5m), 1 x mini Tripod, and 1 x foam wind screen. Software notes include REW support (v5.01 and up; the latest beta release automatically recognizes the microphone and prompts for use when REW starts with it plugged in), Dirac Research recommendation, iPad measurement and SPL meter apps, Mac-only Fuzz measure calibration-file import and automatic SPL calibration, and Amarra Symphony with IRC for impulse response correction and target curves.
