The effortless control and uniquely musical character of one of the best-known vintage compressor / limiters.
Taming the dynamics of a mix is often necessary, but can leave it sounding lifeless and unexciting.
Conversely, the FC70 keeps the mix in check without sacrificing power and detail, emulating the legendary smooth, effortless dynamic control and uniquely musical character of the classic Fairchild 670 limiter.
Modelled using measured data and schematics from genuine hardware, the FC70 uses a fully balanced design, combined with an innovative delay-free feedback algorithm to emulate the original circuitry.
In addition, the sidechain includes the fast attack and program dependent release settings of the original, combined with Lateral / Vertical, Independent and Linked stereo channel modes.
