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.
The ZET Horn in the right light
3.83 million viewers were able to watch our ZET-Horn alongside some well-known actors and actresses on the German TV channel ZDF on Saturday, the 07th of May 2022. The rather unconventional use is surprising, but the horn shows itself in a classic style.
Starting signals
The starting signal for the Kiel Week was finally issued again with our Makrofon after a two-year break. We look forward to a week of festivities, regattas and a wonderful windjammer parade.
