How did we make our EQ more musical?

3 band eqWe started by finding the right frequencies: 

Hi Shelving EQ at 12kHz – Our 402-VLZ3 mixers have Hi Shelving EQ at 12kHz instead of 10kHz. A gentle 12k boost adds detail and sheen (without aural fatigue). Cutting at 12k can take a harsh edge off a sound without emasculating it.

Lo EQ with firm foundations – Down there at the bottom, our 402-VLZ3s have 80Hz Lo Shelving EQ instead of the tubby boom and bonk of 100Hz EQ. 80Hz gives you more control over deep, fundamental bass that’s produced by kick drums, floor toms, bass guitar, and low synth sounds. You can add depth and richness to male vocals, fatten up guitar sounds and create ear-stomping dance mixes.

We improved the interaction of the separate EQ bands:

Shelving equalization found in many mixers gives you an unpleasant bonus in the midrange—when you boost high or low shelving EQ, the midrange gets boosted, too. When you add high- or low-end, you also hear more midrange. So you boost the shelving EQ more. Which boosts the midrange more, etc. This is a vicious cycle. Through careful circuit design and higher quality components, our 402-VLZ3 mixers avoid Hi/Lo-Mid interaction problems. If you want high or low shelving EQ, that's ALL you get. It's a difference you'll come to appreciate.
