Thomas Mundorf started providing PA systems to local bands and event organizers while he was still in school in the 1980s. After graduating, he studied electrical engineering with a specialization in communications and measurement technology. In the 1990s, he started working with renowned American manufacturers, providing technical support in Germany and Europe. These collaborations became so successful in the 2000s that he withdrew from the rental business to concentrate solely on his work as a technical support engineer and freelance audio engineer. He went on to work with the biggest bands and service providers worldwide in the event industry.
