Hypex was founded in 1996 by Jan-Peter van Amerongen as a supplier of amplifier subassemblies for active PA speakers. The products drew the attention of hi-fi speaker manufacturers, resulting first in a line of active subwoofer amplifier subassemblies, shortly followed by multichannel units with active cross-over filters for the studio market.
2003 saw the start of a migration of all products to class D. For this, a licence deal was closed with philips for the "Universal Class D" circuit. Realising the market potential of the circuit, Hypex decided not only to use the technology in completed subassemblies, but also to sell bare amplifier modules to the open market. The UcD180 and UcD400 modules have quickly established themselves as the new standard, both in terms of measured and subjective performance.
In 2005, Hypex decided to become a major player in the OEM class D market and hired UcD's inventor, Bruno Putzeys, formerly Chief Engineer Class D Audio at Philips Applied Technologies. The roadmap includes higher-power versions of the UcD circuit as well as a matching range of switch-mode power supplies.
