The XL2 is currently the world’s most versatile hand-held acoustic and audio analyser. I can do so much with it, and just love it! And in many ways, the associated Data Explorer software is much more versatile and easier to use than other leading industry equivalents.

I must say that the instrument and the software are brilliant, and very simple to use, even for an old fogey like me.

The art of audio repair and restoration is alive and thriving at NTi Audio. They are tech wizards. They brought a beloved Tester back to life.
It had completely failed after being in service for 37 years. This instrument was no longer being manufactured and could not be replaced. NTi stepped in and worked their magic to make it good as new. Bravo! Bravissimo!
