Lexicon

Summary

Abstract

Lexicon reverbs are among the most iconic effects processors in recording history. With 14 mentions across 7 threads, the community discusses the various PCM series hardware units (PCM 70, 80/81, 90/91) and the classic 224. These algorithmic reverbs define the sound of countless records. The hardware units are valued as “preset machines” since their button-based interfaces don’t lend themselves to real-time tweaking. The PCM 60 is noted as the reverb heard on Notorious B.I.G. records.

Key Characteristics

  • PCM 70: Mono to stereo; classic
  • PCM 80/81: Stereo; step up from 70
  • PCM 90/91: Higher-end stereo reverb
  • PCM 60: “The Wallace one” — associated with Notorious B.I.G.
  • 224: Legendary studio reverb; Chase Bliss made a pedal version
  • LXP-1: Affordable entry-level Lexicon hardware
  • Button-based interfaces make them best used as preset machines
  • Hardware units range from affordable (LXP-1) to expensive vintage pieces
  • “They all pretty much rip” across the PCM line

Use Cases

  • Studio reverb processing — the definitive algorithmic reverb sound
  • Preset-based reverb selection during mixing
  • Hardware delay (LXP-1 and similar units)
  • Signature reverb on vocal tracks and instruments

Settings & Sweet Spots

  • Best used as dedicated preset machines — pick a preset and commit
  • PCM units pair well with other rack effects in a studio setup
  • Not ideal for real-time parameter tweaking due to button-based interface

Common Mistakes

  • Expecting to tweak Lexicon rack units in real time like a plugin — they work best as preset machines
  • Not considering that any Lexicon PCM unit will sound good — “they all pretty much rip”
  • Overlooking the LXP-1 as an affordable entry into hardware Lexicon reverb

Mixing Context (from mixing-talk)

In mixing-talk (1,796 reverb/delay messages), Lexicon reverbs are referenced as the industry standard for algorithmic reverb:

  • Valhalla as the modern Lexicon alternative: The community frequently discusses Valhalla VintageVerb and Room as affordable alternatives that capture the spirit of Lexicon algorithms
  • BatMeckley’s Valhalla insight: “what verb you been using on the vocals these days” — and the answer from a professional mixer was simply “Valhalla” with default-ish settings
  • chrissorem’s real plate vs Lexicon: chrissorem uses a real plate reverb as his signature, with Michael Brauer asking about his “plugin settings” — illustrating that hardware reverb still has a place alongside Lexicon units and plugins
