    [TD]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.[/TD]
