ADL 670 Stereo Tube Mastering 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!!

The ADL 670 is a 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.
They also carry direct replacement parts based on original Fairchild 670 design. Please call ADL today for further details: 845 255-4695


Here's an excerpt from a TapeOp review by Pete Weiss on the ADL 670:


" I was able to check out the ADL 670 and A/B it with a vintage Fairchild
670...running identical material through them with matched settings I would be hard pressed to say there was any difference in the two. They both made the mixes louder and thicker without sacrificing any high or low end or distorting in any audible way."
