Once a famous band sound engineer, acoustic engineer, international consulting engineer, I recommend this calibrator which I personally bought/tested. Why do you need a calibrator? 1. How to trust the readings over time. 2. Thus, the results are reflected in the reports for legal entities. 3. I hereby confirm that I have not received any compensation for this review.
