EQ4™ 6 Band Equalizer with AIR BAND

Following its EQ3 and EQ3-D predecessors, the EQ4 provides unparalleled transparency and top end presence while maintaining the true natural sound behind the mix. EQ adjustments are obtained with minimal phase shift and detent controls allow for easy recallable settings. 

The EQ4 offers the legendary AIR BAND™ and five other sonically superior band passes.


Hear it on vocals: Madonna, Celine Dion, Black Eyed Peas, Snoop Dogg, etc.


Because of the Maag Audio EQ4’s unique design, there is very little phase shift. This helps the user keep the integrity of the original sound and enhance the “Airy” frequencies, while tonally shaping the sound from the top to the bottom. The lack of phase shift and the AIR BAND® makes the EQ4® great on anything that needs EQ shaping. 


The EQ4’s band passes all interact with each other. In turning the AIR BAND® gain up, the overall gain will come up a bit as well. Increasing the AIR BAND® gain will also increase the overall gain to a small extent. This is normal and is a necessary byproduct of the design. This happens because of the interaction (summing) of the AIR BAND® with all of the other band passes. This interaction is a necessary part of the design to ensure the integrity of the sound is maintained. To compensate for the added overall gain, simply turn down each of the 5 band pass knobs equal amounts. An example would be two clicks down on all 5 knobs. The EQ will remain the same shape, but the overall gain will be lowered. This compensates for the extra gain added from the interaction of the boosted band passes. This is the correct way to get the desired results from the Maag Audio EQ4®. Here is another way to look at it: If lifting a desired frequency, you may want to consider bringing down the level of the other band passes above and or below; always remembering the band passes interact with each other. This is a different approach from other typical equalizers. 


Understanding how the band passes and the AIR BAND® interact in the Maag Audio EQ4®, will help you better shape your sound; providing unparalleled transparency and top end presence while maintaining the true natural sound behind the source. 


The plugin version has an extra feature, the LEVEL TRIM, which you can use to turn down the overall gain if needed. ALT/click toggles between a reset for each band and the last status, enabling you to easily bypass individual bands.
