KH-EQ1 is a semi-parametric 5-band equalizer plugin by Black Rooster Audio, the second part of the Koen Heldens signature series. It adds harmonic saturation to each band and includes a stepless Mid/Stereo/Side router.
KH-EQ1 is built for shaping individual elements and full mixes with EQ. Each band has controls intended to add color as well as cut or boost frequencies. The developer positions it as a professional studio EQ with a creative edge, aimed at producers who want more character from their equalization. Black Rooster Audio describes it as a signature design developed with Koen Heldens, and each license includes presets created by Koen himself.
Each of the five bands can add harmonic saturation, so boosting or cutting a frequency can also change its color. This makes the KH-EQ1 useful when you want an EQ move to add warmth or density rather than only adjust the tone.
The semi-parametric layout gives you control over the main frequency bands, and the processing is designed to keep the character of each element intact while you reshape it.
The stepless Mid/Stereo/Side router is the feature that sets the KH-EQ1 apart in its layout. Instead of switching between fixed modes, you move smoothly between Mid, Stereo and Side processing.
This is useful for working on the width and center of a mix, such as tightening low end in the middle while leaving the sides open, or adding presence to the sides of a stereo bus.
