MiniDSP UMIK-1 Calibration Microphone USB-C

Measure Your Room, Fix Your Sound

The MiniDSP UMIK-1 is the measurement microphone that turns room correction from guesswork into real data. It's one of the most popular calibration mics for Dirac Live, and the go-to choice for the free REW software: plug it into any Mac or PC and it shows you exactly what your speakers and room are doing, so you can fix the peaks, dips and delays you can't hear but are always there.

Why You'll Love It

• See your sound, don't guess: With the free REW software, the UMIK-1 measures your room's actual response, so you target the real problems instead of tweaking by ear. It's the difference between guessing and knowing.

• Individually calibrated: Every UMIK-1 ships with its own calibration file matched to its serial number. Load it and your measurements are accurate to +/-1dB, not just close enough.

• Plug and play, no drivers: USB-C into Windows, Mac or Linux (or iPad with a camera adapter). It works with REW, Dirac Live and every major measurement tool straight out of the box.

Under the Hood

• True measurement accuracy: A 6mm omnidirectional capsule and 24-bit ADC capture a flat 20Hz to 20kHz, with 133dB max SPL that handles the loudest subwoofer sweeps.

• The calibration file that matters: Your unique file corrects each mic's tiny variations, so REW and Dirac read true SPL and frequency, not an approximation.

• Ready out of the box: Includes a mini tripod, foam windscreen and 1.5m USB cable, with a 3/8" thread that fits any mic stand. USB powered, no batteries.

CHT Insider Verdict

If you own a subwoofer, a MiniDSP or anything with room correction, the UMIK-1 is the first thing you should buy. It's the cheapest upgrade in hi-fi that makes a real, audible difference, because it lets you measure and fix your room instead of hoping. Nearly every calibration and install we do starts with one.

Pro Tip: Download your mic's calibration file from MiniDSP (it's tied to the serial on the barcode) and load it into REW before you measure. Skipping that step is the most common mistake, and it throws every reading off.
