Sie-Q: EQ with IQ

Sie-Q is an EQ that’s hard to make sound bad. Designed for broadcast, its frequencies and curves were carefully chosen to keep things sounding good no matter what. This model of German engineering brings a whole new color to your EQ palette.


  • Get an airy top end with the super-smooth High band
  • Accentuate or tame mid-range details with the switched Mid band
  • Carve out some space or add rich bass with the Low band
  • Push the Drive control to recreate the color of the original EQ

From full mixes to sub-mixes, to vocals and guitars, to drums and percussion, this EQ helps you find the sweetness without the hassle. It’s also a fantastic addition to your master bus–just a touch of the High band can add life and openness. The stand-out feature of Sie-Q is its amazing high-end, which adds space and air, and feels perfect on any track, no matter how much you boost.
