Lexicon PCM70 digital effects processor
The PCM70 is one of Lexicon's finest and most enduring digital effects processors with a distinct personality and magnificent sound. The PCM70 is an industry standard found in all the best studios and often specified as first choice on equipment riders. The PCM70 features a spectacular depth of sonic capabilities and tremendous MIDI effects control, although its presets offer classic Lexicon effects with a few easy button pushes.

Simply Sophisticated
The front panel of the PCM70 does not reveal its sophisticated nature. From this simple array of controls you have access to over 40 preset effects, 50 user registers and 70 variable parameters.

The programs include reverberation, delay, effects combinations including reverse and gated reverb, flanging, chorus, multi-tap delay, spin, circular, pan, filters and a mixture of delay and chorusing.

By adding any MIDI control device such as a keyboard or sequencer, the PCM70 gives you two more ways to control its effects. First, you can store and access your custom sounds in 50 non-volatile registers by associating them with a MIDI Program Change command.

What's more, you can exploit Lexicon's Dynamic MIDI, which lets you modulate up to 10 parameters in real time by patching them to MIDI controls such as Note Number, Modulation Wheel, and Pitch Bender.

"Some things in life go on and on and on and on and… (including me, I hear you mutter…). One such piece of audio kit is the ubiquitous Lexicon PCM70.

There isn’t a top engineer in the world who doesn’t know these little beauties backwards, and most own at least one. From rich vocal reverbs to phased keyboard washes to echoes and delays, the PCM70 is in truth a versatile multieffect rather than merely a reverb, although the algorithms are awesome, as is the sound (hardly surprising as it used the same converters as the classic 480L).

The PCM70 was discontinued because it was too expensive to make rather than because demand dropped. It is of the generation of Lexicons that become a part of the sound rather than flirting around the edges, and as such can be used on almost any signal that need short to medium reverbs (and by medium, I mean a darn site longer than many so called mainframes offer). It’s a little gem, and one that will never go out of fashion. If you’ve got one, you know where I’m coming from. If not, you have a rare treat in store".

Lexicon was the first company to bring digital audio technology to musicians, engineers, and producers more than 20 years ago. Since then, they have developed a world-wide reputation for excellence in digital audio technology. It's called the Lexicon Sound, and today it is recognized as the best in the world. You'll find the Lexicon Sound in abundance in the PCM70.
