Harrison's "Music Recording" series — the desks that sat between the monumental 32-Series flagships and the later compact Raven. The MR3 (Music Recording 3, introduced 1981) was a 24- to 36-channel in-line console carrying the 32-Series topology into a more approachable frame, and gave its name to what remains Harrison's most celebrated EQ circuit — the MR3 EQ — today still offered in 500-Series and plug-in form. The MR-2 was the next step up in frame size, offering the full in-line Harrison topology in a mid-sized package. Harrison Audio still cite the MR series today as one of the lineages that most defined the "Harrison sound" — dynamic, velvety, surgical EQ combined with the in-line workflow Dave Harrison invented.
