The kh eq1 Black Friday deal is 67% off at $19 until Nov 22, 2026, on Black Rooster Audio's semi-parametric 5-band EQ plugin from the Koen Heldens signature series.

The KH-EQ1 is the second part of that series. The maker calls it a professional studio EQ with a twist, and the twist is two things most EQs don't have: saturation on every band and a stepless Mid<->Stereo<->Side router.

What does the KH-EQ1 do?

It shapes frequency response across five bands. The maker says the band controls add color as well as gain changes, and that the functionality is built to push you toward creative sound shaping rather than just corrective cuts.

Each band has its own harmonic saturation. So you can boost a band and push a little harmonic content into it at the same time, all on the same control strip.

How does the Mid/Side router work?

The router is stepless. Instead of flipping between stereo and mid/side modes, you move continuously between Mid, Stereo and Side.

That lets you dial in how much of the EQ lands on the center and how much on the sides of a signal. Handy on a bus where you want a different tone in the middle than at the edges.

What comes with it?

Every license includes custom presets made by Koen Heldens himself. The maker pitches them as a way to start from a finished, professional setup.

Here is the rundown of the plugin's main points:

  • Semi-parametric 5-band EQ
  • Harmonic saturation per band
  • Stepless Mid<->Stereo<->Side router
  • Custom presets by Koen Heldens
  • SSE2 optimized code, with DSP operations pipelined for high-performance processing
  • HighDPI Retina support on Windows and Mac

On Windows, whether HighDPI works depends on your DAW, so your DAW manual is the place to confirm it.

Formats and system requirements

On Mac, you need OSX 10.9 or newer, with an Intel Core CPU or an Apple Silicon M1/M2 processor. Intel and M1/M2 machines are both supported. You also need 1GB of RAM and a 64-bit host that runs VST, VST3, AU or AAX.

On PC, you need Windows 7 or newer, an SSE2 compatible processor (Intel Core recommended), 1GB of RAM, and a VST, VST3 or AAX compatible host. Both platforms call for a display resolution of 1280x1024 pixels or more.

Why an EQ matters in the chain

The maker describes the equalizer as one of the most used and most misunderstood processes in audio. It adjusts the response of chosen frequencies, which makes an element of the mix more or less prominent.

Used on a single track, it handles surgical cuts and boosts. Used on the master track of a final mix, it works in mastering too.
