The AE400 Active EQ v6 from McDSP is four completely overlapping bands of fixed and active equalization for Mac and Windows computers with Q (bandwidth), fixed gain, and active gain controls. It is designed for post production, studio production, and live sound applications.
The AE400 plug-in provides a key filter for each band and allows the active gain response to be as selective or broad as needed based on the Q (bandwidth) control. Each band can use the input signal or selected side chain signal to trigger the active EQ response.
The active EQ bands can be controlled via the response plot itself, or from the text readouts above and below the response plot. The AE400's active EQ response is determined by each band's threshold, attack and release settings. Additionally, a ratio control determines the input signal level sensitivity to further articulate how the active EQ will reach its maximum active equalization.
Peak signal text readouts for each active EQ band's key signal allow quick setup of each band's active EQ threshold, and are located underneath the band's dynamics plots. Input and output controls, individual band bypass, band control linking, and band key signal monitoring round out the features of the AE400.
The Native plug-ins provide AAX-Native for use with Pro Tools, but also includes Audiosuite, Audio Units and VST versions for use with other DAWs including Logic, Digital Performer (DP), Cubase, and Ableton Live.
