Explore a variety of natural sounding rooms with the nuances of inherent realism.

This powerhouse Lexicon reverb uses the latest DSP technology and the finest collection of classic Lexicon algorithms to offer the ultimate audio processor for live sound and studio applications. With over four decades of experience, Lexicon is regarded as a standard in digital audio processing. Building on the similar design and technology of many Lexicon products, the PCM92 is one of the most advanced reverb and effects processors in its class.

The rackmount Lexicon PCM92 reverb delivers 28 mono and stereo reverbs, delays, and modulation effects, flexible routing configurations, and a comprehensive collection of over 1200 finely crafted presets, including recognizable classics from an immense library of sounds.

The Lexicon reverb features Hall, Concert Hall and Random Hall reverb algorithms that are consistently used by live sound and recording engineers because of their ability to reproduce the musical ambiance of large, wide, panoramically wonderful spaces. In fact, these classic Lexicon Hall algorithms have been used on more than 80% of all recorded music.

Lexicon's Room algorithm offers an amazing palette of natural sounding rooms with all the inherent realism of the actual space. Reflection patterns are easily selected, scaled, and equalized all while simultaneously passing audio and the room size can be instantly changed or reversed. These capabilities provide a more flexible alternative to convolution type reverbs due to the precise control and manipulation that is only possible with a reverb synthesizer.

One of the advances in this Lexicon reverb is the ability to create realistic small spaces. For both music and film production, it is often vital to have the ambience of a phone booth or very small drum room. In the Lexicon PCM92 you can create them with a reality never heard before from any processor other than a Lexicon.

In addition, the PCM92 effect processor delivers capabilities to traditional reverbs by adding multimode filters in the audio flow. This allows more exact shaping of the reverb while still maintaining that distinctive smooth, rich "Lexicon Sound." Also, all reverbs have an "Infinite" switch that allows the reverb to run forever, which is useful for creating unusual backgrounds and sound effects.
