The 3624 sat one step above the 2824 in Harrison's 24-Series line — 36 input channels routed to 24 buses on the same architecture. Like its smaller sibling, it featured three-band reciprocal parametric EQ with parametric high-pass filter, two echo sends, nine subgroups, and Automation Ready VCA faders as standard. The 36-segment High Resolution LED meters were available at extra cost over the standard 12-segment bar graph. It offered the same NO COMPROMISE build quality and AUTO-SET readiness of the flagship 32-Series, in a mid-size frame well-suited to regional recording studios and post-production rooms.
