 This was followed by the PP-1 film console, the MR-2, MR-3, and MR-4 music recording consoles, the TV-3, TV-4 broadcast consoles, the HM-5 live console, the Raven music recording console, and the Air-7/Pro-7 broadcast and production consoles.These fully analog console designs continued into the 1990s, while the digital revolution was taking place.During this period of rapid digital development, Harrison still continued to produce analog consoles (often with some digital elements) such as the AIR 790/PRO 790 broadcast and production consoles, AP-100 on-air production console, the MR-20 music console, the industry workhorse TV-950 and Pro-950 production consoles, and finally the TV5.1 surround-capable broadcast console.
