Note* The iLoud is not officially compatible with PC/Windows systems as an audio interface. This is because all Windows systems can include different sound cards. Each sound card can use a different wiring standard rendering the iLoud compatible or incompatible. Our products use the CTIA/AHJ wiring standard.
