AER have been working since 1992 to ensure that their acoustic amplifiers become the benchmark product. The acoustic amplifiers they produce are designed and built to ensure that the sound of the acoustic instrument is produced as near to the original sound as they can get. This involves high quality design, components and manufacture with quality checks being made at every stage of production. To ensure that the products meet their exacting requirements, every amplifier is rigorously tested before it leaves the factory.
