Berkeley, CA - Meyer Sound has added touring sound veteran Don Pearson to its staff of educational trainers as a technical seminar instructor. Pearson co-founded Ultra Sound(now Pro Media/Ultra Sound) in San Rafael, Calif., with Howard Danchik in 1978. The company established a reputation for taking a studied approach to sound reinforcement and providing pristine audio for its clients, who have included the Grateful Dead, Santana, the Dave Matthews Band, Andrea Bocelli and many others. Pearson left the company in spring 2004 to be an independent consultant providing audio services, including system tuning and educational seminars.

"We have known and worked with Don for many years," says Helen Meyer, executive vice president, "and have always respected his devotion to combining the science of sound and the realities of touring sound reinforcement. Don's reputation is based on the results he achieved from that work, and we know that his knowledge and experience will be a powerful addition to our educational efforts."

Pearson joins a team of instructors that includes Bob McCarthy, who founded Meyer Sound's educational effort with his SIM School.

The addition of Pearson comes immediately on the heels of the completion of a state-of-the-art 57-seat training theatre at Meyer Sound's headquarters. The theatre incorporates desktops and Internet connections at every seat and can support nearly six tons of weight, making training possible in everything from proper rigging techniques to Meyer Sound tools such as SIM and Meyer Sound MAPP Online software.


Don Pearson was cofounder, president, and chief engineer at Ultra Sound Incorporated for twenty-five years. For seventeen of those years he was on tour with Grateful Dead whoís live sound was recognized as the ultimate live sound experience. He was responsible for design, engineering and operation.

Prior to Grateful Dead, he worked for Jefferson Airplane, Hot Tuna, Jefferson Starship to name but a few. More recently, while touring with Andrea Bocelli, he accepted the challenge to provide a positive audio experience with a large symphony orchestra and tenor/soprano vocalists in a hockey rink/basketball gymnasium environment (Sports Arenas).

Donís expertise is extensive and has been utilized for over 2500 live events. From the largest festivals to the smallest intimate club settings, he is familiar with all aspects of providing unparalleled sound system engineering, concert/event planning and implementation.

In 1978, he published a technique for making impulse response measurements, in Recording Engineer/Producer Magazine. 1,2 In the mid 1980ís, Grateful Dead Productions purchased a BrŁel and Kjśr 2032 dual channel FFT analyzer. Using this analyzer, Don developed a method for adjusting the interaction between the sound system and itís environment. This technology, along with techniques developed by others, was the basis for the Smaart software analyzer.

He was a principle on the development team for the analysis software known as Smaart, and has been teaching courses on its usage since Smaartís Version 1 release.

Don has performed system optimization for over one thousand live events including many musical concerts, performances at legitimate theaters, Woodstock, Olympic events, presidential conventions and inaugurations, and numerous benefits.

Don has and continues to consult with many major equipment manufacturers. Due to Non-Disclosure Agreements, these companies cannot be identified.

In 1999 Ultra Sound Incorporated was sold to Pro Media. Mr. Pearson continued at Pro Media as senior engineer until May 2004, when he left to become an independent consultant. Ultra Sound continues to provide sound systems for many national touring groups; most notable are Dave Matthews Band, The Dead, Primus and Andrea Bocelli.
