The American 5 Dynamics, originally released in the 70s, is a fet feedback type compressor. Equally useful as a tracking, mixdown or program compressor/limiter, the A5D utilizes "vintage" dynamics control and an easy to use multi-function control set. It delivers dynamics control behavior unlike VCA feed forward compressors so common today. American 5 Dynamics makes use of the 2510 and 2520 op-amps and manages to sound clean but with character without being weak and harsh.

    Note for MAC users:
    From Acustica Audio: "After several tests, we have detected that our products do not run correctly in the Rosetta 2 mode and we recommend using always application with a specific build for Silicon computers."
    To use ULTIMATE libraries on MAC computer you need to upgrade to Nebula 4.5 (rev. April 2022) also.
