where they developed an interest in broadcasting technology. As a

In 1996, the new mixer was presented at the AES Exhibition in
Copenhagen. The results encouraged further development of the product.
In September 1997, the first mixers were supplied to the German Public

The products of DHD are almost completely manufactured in-house – only
the mechanical parts are supplied by specialized companies. This
ensures that customer demands can be satisfied within a short time and
in high quality. After having moved again within the city of Leipzig, a
new Surface Mount Technology production line was taken into operation
DHD started its business with public broadcasters, but also sells to private radio stations.
The international business of DHD started in 1998 and is carried out by

France, Italy, The Netherlands, Belgium, Luxembourg, United Kingdom
(BBC), Austria, Hungary, Poland, Russia, Australia (Olympic Games
2000), Guadeloupe (French), French Guiana, Tunisia, Morocco, Turkey,
