API 550A Plug-in

Modeled on the late 1960's legend, the API 550A EQ provides reciprocal equalization at 15 points in 5 steps of boost divided into three overlapping ranges. The high and low frequency ranges are individually selectable as either peaking or shelving, and a band-pass filter can be inserted independently of all other settings. The 550A is a uniquely powerful equalizer with that one-of-a-kind API sound.
