Detlef Hoepfner has been familiar with his "live sound" theme since the late 1980s. Combined with his second foothold in the media and publishing industry, he was already involved in magazines such as PRODUCTION PARTNER and LICHT & TON FÜR BANDS, which he still accompanies and is responsible for. If you ask him, who lives with his family between Cologne and the Ruhr area in Wuppertal, to his greatest enthusiasm, it is difficult for him to decide whether he wants to be on the mixing desk or push ahead with online and print content production. In case of doubt, the change of scene into a small sailing dinghy will help him: in NRW and the district of Lauenburg, he is actively involved on the water to strengthen children and adolescents.
