Lexicon 224


Like so many other studio mainstays, artificial reverb effects were first developed in the analogue era and later updated and developed further as digital technology began to take over. German audio equipment manufacturers EMT, not content with just about perfecting the plate reverb with the EMT 140, pioneered digital reverb with the 250, released way back in 1976.

The 250 was a revolutionary unit, but it was superseded a couple of years later by a company whose name went on to be synonymous with top-quality digital reverb. Lexicon’s 224, released in 1978, was the first true industry standard digital reverb, capable of some of the smoothest, most useable reverb algorithms ever produced. The functional black rack unit itself might be nondescript, but the iconic LARC (Lexicon Alphanumeric Remote Control) unit can still be found resting conveniently on the mixing consoles of countless studios to this day.

The 224 in particular marks an early high point for algorithmic reverb. Before the advent of convolution reverbs and more advanced forms of algorithmic modelling, the standard was for all digital reverb units to be based on relatively simplistic delay-based algorithms (albeit running on what was at the time cutting-edge digital signal processing hardware). That’s not to say that they didn’t sound good; indeed, with its 12-bit AD and DA conversion (again, the highest quality available at the time), the 224 offered exceptionally long, clear reverb tails.

The iconic status of the 224 means that a good working unit still commands a relatively high price, typically in the region of £1,500. More affordable Lexicon units such as the later PCM range offer a similar sound at a lower price point. However, it’s impossible to ignore the fact that software emulations of digital reverb units are all but indistinguishable from the real thing. Universal Audio’s Lexicon 224 Reverb plugin uses exactly the same algorithms and control processor code found in the final iteration of the 224. For most users it’s a cheaper, more flexible and more convenient alternative to the original hardware.
