The Fairchild 670 compressor's attack and release times are controlled by the switch labeled 'time-constant' and those settings are as follows. The Fairchild 670 compressor is a well-known vintage stereo limiter that was released way back in the 1950s by Fairchild Recording Equipment Corporation. The FC70 uses state of the art processing to emulate a fully balanced transformer-coupled signal path, combined with an innovative delay-free.

Inspired by the legendary smooth, effortless dynamic control and uniquely musical character of the classic Fairchild 670 limiter, the FC70 tames dynamics without robbing the mix of power and detail.
