Heritage Audio has debuted clones of the famed Fairchild Model 660 (mono) and Model 670 (stereo) tube-based compressors. The original, invented by Rein Narma in the 1950’s, has been utilized on thousands of hit records over the past six decades and is much sought after, since only around 500 or so units were produced.

Not that there haven’t been dozens of other clones and plug-in emulations over the years, Heritage has debuted their own versions, the Herchild Model 670 and Model 660, which, of course, they claim is “a faithful reproduction to the original as it contains 22 valves and 9 transformers, operates at a very high voltage and uses only the best components to deliver the utmost quality possible.”

While staying true to the original in terms of response and sound, Heritage Audio has able to add a few things to make it more practical in modern day studios. First off they’ve given direct access to the continuously variable DC THRESHOLD (Slope/Ratio/Knee) control. This is something that makes the compressor more flexible and was only available on the original via an inconvenient screw adjustment hidden from immediate access. It’s easy to go from a soft, unnoticeable, light compression to a heavier, harder limiting, as well as everything in-between. Then there’s the SC FILTER. Nowadays, it’s just about impossible to fathom a compressor without this feature as it’s become so important in everyday use. Here they’ve provided four different frequencies to choose from to precisely tailor your compression needs. The exact Attack and Release times have also faithfully been reproduced in the TIME CONT section with the same six settings as the original so you can confidently recreate the feel of its ancestor.

In addition, it can be used as two individual processors or linked together for either Stereo use or the ever more popular Mid/Side processing. There are actually four modes of operation: Individual, Link(Stereo), LAT/VERT(MID/SIDE) & LAT/VERT Link. Using the LAT/VERT mode provides a whole new world of creative options to your mix.
