The Lexicon MPX Series, introduced in the late 1990s, brought the company’s renowned reverb and effects algorithms to a new generation of affordable processors. Starting with models such as the MPX 1, MPX 100, MPX 500, and MPX 550, the series offered high-quality reverbs, delays, modulation, and pitch effects derived from Lexicon’s flagship PCM range. Combining 24-bit digital processing with intuitive front-panel control and MIDI integration, the MPX units delivered the classic Lexicon sound in a compact and accessible format. Favoured by musicians, studios, and live engineers, the MPX Series extended Lexicon’s legacy of rich, spatial effects to a broader audience without compromising sonic quality.
