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.
AnaMod 670’s Automatic Gain Control (AGC) Modes
- Left/Right: Dual Mono (split) operation
- Stereo: Left and Right channels are linked
- Lat/Vert: Left and Right channels are Mid-Side (M-S) encoded, compressed separately, and decoded back to Left/Right
