Years ago I ‘lunchboxed’ one of those above-depicted RCA BE100 equalizer modules. The RCA 100 series of the early 70s was the end-of-the-line for RCA’s pro audio gear. The series consisted of the MI-141651 op amp, the BMM-100 Mixer (channel strip, aka MI-141550), BE-100 EQ (aka MI0141560), BA-101 and BA-103 preamps (also designated as MI-141501, MI-141503), BMM-110 Submaster module (aka MI-141570), and BIM-100 Isomix amplifier (aka MI-141520).
Since I seem to be one of the few fools who has publicly admitted to spending time messing around with these things, I’ve gotten several requests over the years for the accompanying data and schematics. Well guess what. TIME HAS COME TODAY. Download all of the tech date for all of these modules.
