Milford, NH (February 10, 2017)–Adamson Systems Engineering has been using Earthworks M23 measurement microphones for tuning its touring and installation loudspeaker systems.
Brian Fraser, senior applications engineer and product manager at Adamson, noted, “At Adamson, we wanted to improve our system tuning kits, so we started looking at the M23, as it is significantly shorter than the M30, which made it easier to carry around and use, and less susceptible to potential damage. Right now, our team of audio engineers uses the M23 for many tasks, including system setups while on the road or in training.”
Last year, Fraser used the M23s around the world, both in Egypt and Ecuador in the middle of summer, and outdoors during the middle of winter in Canada. In all these cases, he employed his preferred method of working with the mics.
“When using multiple measurement microphones to test a big PA, my preferred method is to place one in the near field, one in the far field and then one or two in-between, all on-axis to one of the main hangs. You can then compare the response of the PA at varying distances from the speakers, using a live average, such as what is available in Smaart 7 and 8.
“I typically do not use the correction software for the Earthworks measurement microphones because the variance between microphones is very low, typically between 0.2 or 0.3 of a dB. What I am looking for are overall sonic characteristics of the PA and the interaction with the space I’m in, as an issue seen in one area of the coverage is not always evident in others, and therefore trying to fix that issue may affect the response negatively for the rest of the audience.”
