Three modes of compression and limiting
Six original 670 time constants plus two new variations
Additional option to operate in true stereo
All analog—no latency or digital conversions
3U rackmount form factor
The Fairchild 670 limiter is the most famous and sought-after stereo compressor ever made. The magical way it adds density and dimension to a track or a mix has been demonstrated on many of the best-sounding records made in the last 50 years. For buss compression, the 670 Limiter is the standard by which all others are judged. Using the AnaMod Process™ to model the complex transformer and tube interactions of the vintage hardware and re-implementing it entirely with analog components, the AnaMod 670 delivers a faithful recreation of the classic unit`s sound and compression action. Unlike digital plug-ins or DSP-based outboard gear, there`s no latency and no A/D or D/A conversions to compromise the sound. Like the Fairchild 670, the AnaMod 670 provides Left/Right (dual mono), and Lat/Vert (M-S encode/decode) modes of dynamics processing. It adds a true Stereo mode, which links sidechains of the two channels.
