ACQUA - Amethyst3


AMETHYST is a VST/AAX/AU plug-in suite which reproduces the sonic behavior of all the components of a channel strip as found in one of the most revered British consoles of all time. It includes an equalizer, a dynamic processor and a preamp stage.

Amethyst3 includes:
Amethyst3 Channel-Strip (Commercial Version)
Amethyst3 Standalone Modules (Commercial Version)



Amethyst3 is a high-performance channel-strip giving you the warm sound of some celebrated British consoles from the late 70s and early 80s.
Amethyst3 includes 3 sections: a preamp, an equalizer-plus-filters, and a dynamic processor. Each of these sections is also available as a single plug-in module, for more versatility. 

The filter section integrates 2 filter sets (A-B mode). The EQ section includes, in addition to the previous equalizer (A), a new emulation (B) that has been derived directly from the same product line of the compressor.
The circuitry behind the new EQ is based on an extensive research conducted by the famous British audio designer and you will hear that same “expensive” sound precisely emulated in this plug-in.

Besides offering a complete brand new set of EQ curves, this “B” emulation is characterized by 2 controls: GLOWY for the LF section and SHINY for the HF section. These controls allow you to change the slope of the low and high-shelf cells, thus altering the overall tonal balance of the sound without changing its character. 

Amethyst3 is based on a mixing desk which was critically acclaimed as one of the greatest sounding consoles of all time. If you’re looking for a channel-strip that is able to enhance and massage your music at its best, then your search is over: AMETHYST3 is your perfect choice!
