The Fairchild 660 limiter is arguably one of the most famous and sought-after compressors 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.
The AM660 is a faithful recreation of the classic sound and compression profile of the 660, using the AnaMod™ process to model the complex tube circuitry of the 660 and implement it entirely in the analog domain. Unlike a digital plug-in or processor based outboard gear, there is no latency, and no A/D or D/A conversions to compromise the sound.
