For over 20 years, NEOsystemes has developed innovative switched-mode solutions to propose last generation class-D products, through a range of performant amplifiers and power supplies. Our knowledge brings smaller and lightest modules, along with outstanding efficiency, offering standard and custom OEM solutions for PA, professionals and consumers. 


Coming from an aeronautical company, our power conversion background enables us to offer reliable, compact and efficient switching mode power solutions. Since 2003, NEOsystemes has dedicated its knowledge to bring innovative audio amplification solutions. 


Based near Bordeaux, our engineering department has developed 100% proprietary technologies within ultra-compact modules. Through embedded amplifiers or resonant mode switching power supplies, we provide custom applications designed for dependability and performance whatever the system. From airports to home, we supply you everywhere to power up your sound.
