Description

The 573EQ Classic Inductor Equalizer brings the timeless musicality of the legendary 1073-style equalizer into a versatile 500 Series format, delivering the rich analog character and smooth tonal shaping that recording and mixing engineers have relied on for decades. Designed for precision and consistency, it features premium Swiss-made ELMA switches across all four EQ bands, allowing for accurate, repeatable adjustments while preserving the warmth and depth that define classic analog sound. Its balanced circuitry integrates seamlessly into modern studio workflows, making it an excellent choice for tracking, mixing, and mastering.

From subtle tonal enhancement to more focused corrective shaping, the 573EQ offers exceptional flexibility across the entire frequency spectrum. The low frequency section delivers a full, controlled foundation, while the midrange provides smooth, precise control for refining vocals and instruments with clarity. The high frequency band adds open, detailed presence that helps recordings feel more spacious and defined, and the integrated high pass filter keeps low end content clean and focused. Whether used on individual tracks, stereo buses, or the mix bus, the 573EQ adds depth, clarity, and classic analog character to virtually any audio source.
