Update on Audio Systems Academy

We are deeply saddened to announce that as of October 2024 Audio Systems Academy is no longer operating as a business. Thank you to the many individuals who attended our classes/seminars through the years. We were honored to be apart of your journey to understanding the modern sound system. Moving forward we will be selling Duncan Fry's book, Live Sound Mixing through GP Lorenzen.

Thank you, Gary and Patti
