API 550B Plug-in

Featuring four overlapped EQ bands, the API 550B is invaluable as both a problem solver and a sweetening device. With 7 switchable filter frequencies spanning up to 5 octaves per band, the 550B's "Proportional Q" automatically widens the filter bandwidth at minimal settings and narrows it at higher settings. It even lets you undo previous processing, affect or even reverse tonal modifications. With its vast range of tonal possibilities, the API 550B is a versatile EQ for all your processing needs.
