The Lexicon M93 is a rack-mount digital delay processor made by Lexicon Pro. On its product page, Lexicon describes it as a "Prime Time Digital Delay Processor", a dedicated delay unit in the maker's line of Prime Time processors rather than a general-purpose multi-effects box1. It belongs to the delay family of effects, covered more broadly on the Delay Pedals type page.
Lexicon Pro lists the M93 as discontinued, so it is no longer part of the company's current product range1.
What it does
The M93 is a delay processor: a unit whose core job is to repeat an incoming signal after a set interval, from short slapback-style repeats to longer echoes. Lexicon's own description of the unit as a "Prime Time Digital Delay Processor" places it in the company's Prime Time line of delay processors1. Because it is a rack unit rather than a floor pedal, it is designed to sit in an equipment rack and be patched into a signal chain or effects loop rather than placed on a pedalboard.
