The Lexicon 224 digital reverb announced in 1978 is the kind of stuff legends are made of. It is without a doubt the most admired and desirable reverb of the Lexicon line-up. It may be over 40 years old now, but the Lexicon 224 is still in use today at many studios regardless of it's limited bandwidth, and is loved by so many engineers, that they will only replace it when it dies. If it dies...
Unveiled at the AES Show in 1978, the Lexicon 224 was not the first digital reverb (that honor goes to EMT’s 250), but the 224 (and its 224X and 224XL cousins) was the most ubiquitous and popular high-end studio reverb in history.
The Lexicon 224 introduced in 1978 and manufactured through to 1986, is an early digital reverb that was well known for its spacey, extra long decays. Vangelis was an early pioneer of the extra long decays using this unit, most famously in the Blade Runner soundtrack.
The reverb was conceived when Dr. David Griesinger, a nuclear physicist/musician/classical recording engineer, started working on a digital solution to reverb. Seeing EMT’s 250 encouraged him to merge a microcomputer with his reverb design.
He pitched his rough prototype to Lexicon, which bought the invention and brought Griesinger on board to help refine the product. One of Griesinger’s concepts for the new reverb was creating a separate control unit for parameter adjustment and program access.
The 224 reverberation system had a console-top controller with a four-rackspace brain, two inputs, four outputs and interchangeable programs to simulate chambers, plates and rooms. The 224 was “affordable” – meaning $7,500 with two programs or $7,900 with four programs.
But at half the price of EMT’s 250, the 224 was a hit. Eventually, the 224 evolved into the improved 224X which used a higher sampling rate of 34.5kHz instead of the 224’s 20kHz and 224XL, which included the LARC (Lexicon Alphanumeric Remote Control), offering fingertip access to programs and parameters, dedicated function keys and a 24-character LED.
The Lexicon 224 used a fixed point processor, with a 16-bit word size. It was designed in the late 1970s using the best technology available, which at the time was the 8080 microprocessor, 12-bit converters (using DAC80 DAC IC), input transformers, and bucket loads of 74S/LS-series logic.
Although the converters themselves are 12-bit, a clever scaling circuit gives an extra 24dB of headroom by actively shifting the input gain. This gives a 16-bit conversion range overall, though precision is still only 12-bit.
From Talking Heads’ Remain In Light through to U2’s Unforgettable Fire, the Lexicon 224 has been used on some of history’s most iconic records and truly earned it’s place as one of the most desirable digital reverbs ever made.

Great sounding machine that has served me well since I first bought it in the 70’s. Recently rebuilt the power supply and did some component updates. The Lexicon 224 has it’s own sound and works well with my Lexicon 480L and my Lexicon 300L. Just too bad Lexicon sold out to Harmon!
