Sós, who will take up the same role with sister company, BroaMan, hails from Budapest and is multi-lingual. He has wide experience in both system integration and sound engineer roles within the theatre world and as a freelance, and is proficient on many industry leading digital platforms, including Optocore partner DiGiCo, as well as Focusrite Pro and Dynacord.
