McDSP AE400 Active EQ HD v7

The AE400 consists of four fully overlapping fixed and active equalizers.

Each band has its own frequency, Q, fixed gain, and active gain, plus threshold, ratio, attack, and release active equalizer response controls. Bands can operate independently, or in a variety of linked configurations. Active equalization can be triggered by the input, or a selected side chain.

Active equalization is triggered by signal level rising above the selected threshold for a given band. There is also the option to invert the threshold behavior to cause the active equalization to be triggered by signal level falling below the selected threshold for a given band.
