ResoNix Measurement & Tuning Kit

ResoNix Recommended Tuning & Measurement Kit

This is our go-to measurement bundle at ResoNix, built specifically for accurate DSP tuning, acoustic measurement, and system calibration while following our ResoNix DSP Tuning Tracks & Guide. It includes the two pieces of gear we trust every day: the Earthworks M23 G2 precision measurement mic and the Audiotec Fischer AMI USB measurement interface. You also get a free 6-foot XLR cable to connect them directly—no guesswork or missing links.

You could buy these items separately, but this bundle saves you $60 versus our standard posted prices and gives you everything you need to do the job right.

The Earthworks M23 G2 is one of the most trusted reference microphones in the audio world, with flat frequency response from 5 Hz to 23 kHz and max SPL handling of 140 dB at full phantom power. Each one is individually calibrated and built from stainless steel with an IP54 rating.

The AMI is a compact, high-quality measurement interface built by Audiotec Fischer, designed specifically to support detailed system tuning and DSP integration. With mic and line inputs, RCA and optical outputs, phantom power, and loopback capability, it gives you precise signal routing and measurement versatility in one compact unit. It works with PC, macOS, iOS, and Android.

This is the exact kit we use for tuning work at ResoNix, and it’s the one we recommend to anyone serious about doing clean, reliable measurement and analysis.
