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 1960s 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 550Bs Proportional Qö
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 560s curve shaping potential is
unmatched while APIs 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.
