Developed in association with Automated Processes Incorporated, the API Collection features four precision processors based on renowned API modules: the 550A 3-Band Equalizer, the 550B 4-Band Equalizer, the 560 Graphic Equalizer, and the 2500 Stereo Compressor. Used by engineers worldwide on countless hit records, these modules deliver a sound like no other. And with the API Collection, Waves captures every nuance of their unique sonic signatures.

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.

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.

Based on the 1967 classic, the API 560 10-Band Graphic Equalizer features precision filtering and high headroom, ideal for signal enhancement and room tuning. The API 560's curve shaping potential is unmatched, while API's unique "Proportional Q" design intuitively widens the filter bandwidth at lower boost/cut levels and narrows it at higher settings. And since boost and cut characteristics are identical, previous actions can be easily undone. For precision equalization with unmatched versatility, turn to the EQ heard on top recordings for decades: the API 560.

The API 2500 is a versatile dynamics processor that lets you shape the punch and tone of mixes with absolute accuracy. Its dual channel design lets the 2500 also function as two separate mono channels via a single compression setting. Using auto-makeup gain, you can adjust Threshold or Ratio while automatically maintaining a constant output level. With both "feed back" and "feed forward" compression types, the API 2500 boasts a wide range of incredibly musical parameters which have made it a favorite of engineers the world over.
