miniDSP UMIK-1

USB measurement microphone

The miniDSP UMIK-1 is an omnidirectional USB measurement microphone supplied with its own unique calibration file, ensuring reliable, repeatable acoustic measurements. Driverless and ready to use, it connects directly to your computer to analyse, tune and calibrate your audio systems with ease.

Design and connectivity

Housed in a sturdy, compact die-cast aluminium body, the UMIK-1 features a 6 mm electret capsule and a sound card with a 24-bit ADC. It connects via USB-C (USB Audio Class 1.0), powered at 5 V by the USB port, with a blue status LED. No external box or phantom power is needed: a single cable is all it takes.

Individual calibration for precise measurements

Every UMIK-1 ships with a unique calibration file linked to its serial number (format 700-XXXX), available as a free download from the miniDSP website. Once this file is loaded into your measurement software, the microphone offers a frequency response of 20 Hz to 20 kHz within +/- 1 dB, for professional-grade accuracy.

Universal software compatibility

Driverless, the UMIK-1 works immediately on Windows, Mac OS X and Linux, with no driver installation. It is the reference microphone recommended by miniDSP and Dirac Research for calibrating their software. It is fully compatible with the main acoustic measurement and correction solutions on the market, such as REW (Room EQ Wizard) and Dirac Live.

Use cases

Ideal for measuring and calibrating your listening rooms, the UMIK-1 is aimed at home cinema enthusiasts as well as installers tuning a hi-fi system, a multichannel installation or an in-car audio system. Supplied complete with a mini tripod, windscreen and carry case, it is ready to measure straight out of the box.
