Welcome to HEDD | Heinz Electrodynamic Designs. We are a Berlin based manufacturer of analog state-of-the-art studio monitors for all segments of music production, broadcast and installation. We also developed a modular input card system called the HEDD Bridge which enables each of our Series ONE loudspeakers to handle digital audio protocols such as AES3/EBU and yes – even Dante and AES67 / Ravenna Network (Audio-over-IP).
