ACQUA - Scarlet4



SCARLET4 is a VST/AAX/AU plug-in suite specifically tailored for mastering engineers. It brings you the sound of two celebrated, specialized mastering devices designed in the '70s by two legendary pioneers, considered the most ingenious minds in the field of music recording technology. These two specialists joined forces to create the first parametric equalizers to ever appear on the audio market. Given how rare these models are, there is no sum of money large enough to persuade their lucky owners to part with their beloved unit.

The transparency of their sonic trademark and the quality of their electronic and mechanic components wholly justify the reputation these tools earned over the years: military-grade rotary switches, precision resistors, proprietary discrete op-amps, without any capacitor on the signal path.


Scarlet4  represents the natural evolution of our acclaimed Scarlet plug-in. To further meet the needs of demanding mastering engineers, we included two different EQ models: SCARLET4 EQ and SCARLET4 CLASSIC EQ, thus ensuring greater flexibility and the highest level of sonic excellence.
