Anthony Demaria Labs ADL 670 Stereo Limiter
There’s no doubt that the original Fairchild 670 was and still is the “Big Daddy” of tube compressors. That’s why people don’t hesitate to pay over $30,000 for one if they can find it. Unfortunately, most of these units are getting very old and unreliable and don’t sound as great as they once did. Well, what if you could buy a brand new one today…with a warranty…for substantially less!!! Can’t be…well, guess again!!
Our premium channel strip boasts frequency response from 10 Hz all the way up to 45 kHz and offers all of the features you’d want in a high-end device. And the ADL 700 is a great value — as you expect from PreSonus!
Introducing the ADL 670, the perfect copy of the original Fairchild 670. After years of testing and research, Anthony DeMaria Labs has matched part for part the specs and sound of the original unit. Every detail has been scrutinized to perfection…no corners were cut. Yes…believe it or not, ADL has painstakingly sourced all the parts of this puzzle to offer a very limited run on these uncompromised, untouchable sonic giants!!! Many in the past have attempted to reproduce the sound of the classic Fairchild 670 but no one until now has taken it to the level ADL has with the ADL 670 compressor. With it’s beautiful “military strength” chassis, stand alone PSU, 20 vacuum tubes and 14 transformers…it doesn’t get fatter than this. Call ADL today to find out more. Somebody had to do it.
We also carry direct replacement parts based on original Fairchild 670 design. Please call ADL today for further details.
