Waves API 550 User Manual

1.2 Product Overview
The Waves API 550 consists of the API 550A, a 3-Band parametric equalizer with 5 fixed cutoff points
per band and the API 550B, a 4-Band parametric equalizer with 7 fixed cutoff points per band.
Modeled on the late 1960’s legend, the API 550A EQ delivers a sound that has been a hallmark of high
end studios for decades. It 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.
Featuring four overlapped EQ bands, the API 550B features 7 switchable filter frequencies spanning up
to 5 octaves per band. “Proportional Q” automatically widens the filter bandwidth at lower 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 an exceptionally versatile EQ.
