The EQ4 is a six-band equalizer featuring the renowned AIR BAND, designed to deliver exceptional clarity and presence without compromising the natural tone of your mix. Building on the legacy of its predecessors, this equalizer offers precise tonal shaping with minimal phase distortion, preserving the integrity of the original sound. Its intuitive detent controls allow for quick and consistent recall of settings, making it an essential tool for enhancing high-frequency content while maintaining a balanced overall sound.

This equalizer stands out due to its unique interaction between the AIR BAND and the five other bands, which collectively contribute to its distinct sonic character. When the AIR BAND gain is increased, it subtly raises the overall gain because of the summing effect with other frequency bands. This design ensures a smooth and natural enhancement of the upper frequencies. Users can easily compensate for this by adjusting the other bands uniformly, maintaining the desired tonal shape while controlling overall levels. This approach differs from typical equalizers and offers a refined method for shaping sound with transparency and depth.

The plugin version of the EQ4 includes additional features such as a LEVEL TRIM control for managing output gain and a convenient toggle for resetting or bypassing individual bands. Its versatility makes it suitable for a wide range of applications, from mastering to individual track processing. Praised for its musicality and transparency, the EQ4 is particularly effective on master channels where subtle enhancement of the air frequencies can bring mixes to life without harshness or loss of detail.
