EQ

API 550A

Waves

The API 550A is a 3-band parametric equalizer modeled on a late 1960s API design, delivering the warm, musical sound that defined high-end studio recording for decades. It offers reciprocal equalization across 15 points with switchable peaking or shelving on the low and high bands, plus an independent 50Hz–15kHz bandpass filter. With Proportional Q technology that intuitively adjusts bandwidth based on gain settings, the API 550A allows aggressive equalization while maintaining smooth, natural results.
