The API 550A/BNative from Waves comes with plug-in models of two classic API equalization modules.
The API 550A plug-in is modeled on the late 60's legendary hardware. The software provides reciprocal equalization at fifteen points, in five steps of boost, divided into three overlapping ranges. A band-pass filter can be inserted independently of all other settings.
The API 550B features four overlapped EQ bands. It features 7 switchable filter frequencies spanning up to 5 octaves per band. It even lets you undo previous processing, affect, or even reverse tonal modifications.
Together, the API 550A/B equalizers add a wide array of classic tonal options to your production toolbox.
"Proportional Q" The filter bandwidth automatically widens at minimal settings and narrows it at higher settings
