AER - The Acoustic People

For many years, AER has been the reference, the gold standard for enhancing acoustic instruments. Many barriers have to be overcome in order to do this. AER amplifiers were founded in the 1990s as a three-man show in the heart of the Ruhr area, and after many years of trial and error, development, and research, they have become the quality and sound standard globally. Udo Rösner, Michael Eisenmann, and Susanne Janz dreamed of creating an acoustic amplifier that would set a new standard for sound and quality for musicians all over the world.
