Miniature sound
The model maker Axel Hüttemann wrote to us about the technical drawing of a ZET-Horn from the mid-20th century and asked for the technical drawing.
Safe at sea
The "Deutsche Gesellschaft zur Rettung Schiffbrüchiger (DGzRS)" translated German Maritime Search and Rescue Services. The NGO takes care of safety at sea every day, with mostly volunteers.
Development of the Diamond Triple Makrofon YM125
Many hours of work, heart and soul and technical expertise had to flow, until we can now proudly hold the first prototype in our hands.
