D2-MAC is a satellite television transmission standard, a member of Multiplexed Analogue Components family.[1][2] It was created to solve D-MAC's bandwidth usage by further reducing it, allowing usage of the system on cable and satellite broadcast.[3][4] It could carry four high quality (15 kHz bandwidth) sound channels[5] or eight lower quality audio channels.[6] It was adopted by Scandinavian, German and French satellite broadcasts (CNBC Europe, TV3 (Sweden), TV3 (Denmark), EuroSport, NRK 1, TV-Sat 2, TDF 1, TDF 2, etc.).[7][8][4][9][10][11] The system was used until July 2006 in Scandinavia and until the mid-1990s for German and French sound channels.
