The API 550A is a true classic — an EQ that’s been embraced by the pro audio community for over a half-century and an industry standard by which other equalizers are judged. Today’s 550A Special Edition celebrates a storied legacy of hit shaping with a limited run of the legendary 500 Series module in a gorgeous vintage cream finish. Designed by API founder Saul Walker in the late ’60s, API’s iconic 550A is one of the all-time classic console equalizers (and 500 Series EQ modules). Offering three bands of definitive API parametric equalization with five judiciously selected frequency centers available on each band, the 550A has shaped the sound of countless recordings, and it remains one of the most sought-after EQs on the planet.
