Half a century ago API blazed a new trail in audio processing. The API 550A and 550B EQs prioritized musicality and transparency while the API 560 elevated the graphic EQ to new tone-shaping heights. Pure and sweet these EQs set new design standards. But EQ wasn’t all: the API 2500 Compressor’s versatile tone and punch remain highly coveted.
API was ahead of its time—and today the API Collection is here for a new generation of producers. API 2500: Vintage to Modern Tones The original API 2500 Compressor bent the rules with two compression topologies—you could choose “Feed Back” compression for the smooth vintage leveling-amp sound or “Feed Forward” compression for a snappy modern response. The API 2500 plugins offer both.
Secret-Weapon Compression for Hip Hop and Club Sounds It’s no wonder the 2500 has been embraced by cutting-edge mix engineers—its Thrust option is the key to killer kicks and booming bass. Nothing else can decrease low-frequency pumping while compressing the highs so well. API 550: Two EQs Two Philosophies The 550A and 550B EQs shared the same exacting standards and sound quality but targeted different needs.
