MicMix was an American professional audio manufacturer best known for its Master-Room reverberation systems and distinctive analogue studio effects. During the 1970s and 1980s, the company produced a range of studio processors including spring reverbs, flangers and other effects, with products such as the Master-Room reverberation units and Dynaflanger finding their way into professional recording studios. MicMix equipment is particularly associated with the period when engineers were increasingly using dedicated outboard processors to expand the range of effects available during recording and mixing.
