The Lexicon PCM92 is the touring continuation of the Lexicon legacy that gave the world the 224, 480L, and PCM81 — lush, lead-vocal-defining reverbs that have shaped the sound of live shows for forty years. Two channels of true-stereo processing, AES/EBU + analog I/O, and the iconic Lexicon hall, plate, and chamber programs that engineers reach for on lead vox and drum room sends. Expensive, indispensable on high-end FOH rigs.

The payoff
FX Processor decisions, organized around the whole rig.
The PCM92 is Lexicon's touring-grade flagship reverb, and it carries real weight behind that title. The lineage — 224, 480L, PCM81 — isn't marketing copy; those boxes defined what a large hall or warm plate sounds like on a live vocal for forty years, and the PCM92 continues that algorithm work in a single 1UThe standard slice of rack height: 1U = 1.75″.

You're buying it for the reverb character: the way a Lexicon hall breathes around a lead vocal without masking intelligibility, or the way a plate settles under a snare without turning to mud. This is a dedicated effects processor, not a multi-effects Swiss army knife, and that focus is exactly the point.

Save and name your show-specific programs to user banks before load-in; the factory presets are a starting point but you'll dial in hall size and pre-delay to the room on day one, and losing that work at the next power cycle is a painful reset.

H9000The Eventide H9000 is the flagship of Eventide's 40-year reverb/delay/multi-FX legacy — 16 stereo effect engines running in parallel, with full FaderPort-style control surface integration and Dante / MADI / AES routing. On a high-end touring rig it replaces an entire effects rack: every reverb, delay, harmonizer, and shimmer the engineer wants is in one 2U box, recallable per song from the show file. The price reflects the position; this is the box on big-budget tours where the FX bus matters as much as the channel inputs.View gear →
Quad CortexThe Neural DSP Quad Cortex is a floor-based guitar and bass modeler with quad-core processing that captures and reproduces amp tones with remarkable accuracy. Its neural capture technology can learn the characteristics of any real amp or pedal, making it a powerful tool for guitarists who want their exact studio tones on stage. Multiple outputs including XLR make it easy to feed both your IEM mix and FOH simultaneously with independent tone shaping.View gear →
Quad Cortex MK2The Quad Cortex MK2 builds on the original with improved DSP horsepower and enhanced connectivity options, allowing for more complex signal chains and effects routing. The updated hardware supports higher-quality captures and more simultaneous processing blocks, which matters for guitarists running elaborate rigs with multiple amp models and effects. If you are building a new rig, the MK2 is the version to get for future-proofing your tone chain.View gear →
