Harrison started building consoles in Nashville in 1975, and the 32 Series that followed became a fixture in studios and film rooms far beyond it. What set those desks apart was a particular midrange character and an equaliser section that engineers still refer to by name decades later. Unlike most of what is sold as vintage console circuitry today, Harrison is the original company, so these are their own designs rather than third-party recreations of them. The current range translates those circuits into formats a modern room can actually use. The 32Classic channel strip and the 32Cpre+ preamp and converter module carry the console preamp, the MR3eq brings the equaliser into 500 series format, and the Comp Dynamics module covers the desk's compression section, so three slots build a complete Harrison channel. The D510 rackmount chassis goes further, combining a 500 series rack with built-in interfacing, and its Dante and mixed I/O cards put that rack onto an audio network so the modules serve a whole facility rather than one room.
