From the moment it was unleashed in 1978, the Lexicon 224 Digital Reverb — with its tactile, slider-based controller and famously lush reverb tail — single-handedly defined the sound of an entire era.

From Talking Heads' Remain In Light to U2's The Unforgettable Fire, the Lexicon 224 remains one of the most popular digital reverb units of all time. Now you can track and mix with this singular piece of audio history with the Lexicon 224 Reverb plug-in.

A Breakthrough in Emulation

Using the exact algorithms and control processor code from the original hardware, the Lexicon 224 plug-in precisely captures all eight legendary reverb programs and the chorus program — based on the Lexicon 224's final and hard-to-find firmware version 4.4. The Lexicon 224 plug-in also incorporates the original hardware’s input transformers and early AD/DA 12-bit gain stepping converters.

Easy Navigation

Every parameter from the original hardware is present in the Lexicon 224 plug-in, and exposed as dedicated sliders and buttons. Lexicon’s distinctive Bass/Mid “split decay” adjustments and Crossover control set the highly tunable reverb image, while the Treble Decay rolls off high frequencies. Use the Depth control to adjust the distance between source and reverb, while Predelay produces a short delay between the sound source and the onset of reverberation. Diffusion affects how quickly the echo density in the reverb builds up over time.

Modeled to the Last Detail

For total authenticity, the UA-exclusive System Noise control enables or disables the inherent dynamic system noise of the original Lexicon 224 hardware — removing the modeled gain stepping, parameter zippering, and quiescent noise. Clicking the “Open” text to the right of the display panel exposes several hidden controls, including Input/Output gain and Pitch Shift, and even a selectable “Bug Fix” mode which enables/disables historical bug fixes from the Hall B and Chorus programs. Taken together, the Lexicon 224 plug-in is the world’s most authentic model of a true studio classic.
