The API 5500 is a 2-channel, 4-band parametric equalizer (\(1\text{U}\) rackmount) that brings the classic, discrete circuitry of the 1960s-era API 550B to modern recording, mixing, and mastering environments. Renowned for its musicality, it features "Proportional-Q" curves, high headroom, and unique range controls, offering 4-band EQ with 7 frequency steps per band
