The Lexicon Pro M300 is a rack-mount Digital Effects System, listed by the maker in its Effects Processors range. Lexicon marks it as Discontinued on its product page, so the unit no longer appears in the company's current lineup.1
Status and related models
The M300 is out of production. Lexicon's product page for the M300L, a related model in the same family, also carries the Discontinued marking as of April 2026.2
Both the M300 and the M300L are discontinued. Lexicon's downloadable documents for the M300 were last updated in April 2026, so manuals and other files remain available on the maker's product page.12
Players looking at Lexicon's processor range will find other units on this site, including the Lexicon MPX 1, the Lexicon PCM81, the Lexicon MX300 and the Lexicon M200, alongside the broader multi-effects category.
