In this video Eli Krantzberg from our sister site Logic Pro Expert shows how the McDSP’s active EQ, the AE400, is used to make threshold dependant EQ adjustments to specific areas of the frequency spectrum.
Although Eli is demonstrating the AE400 on his beloved Logic Pro, hear the AE400 applied to various elements in a multi mic’d drum kit, and discover how using it in sidechain mode helps instruments in the same frequency range come through where and when they need to. Explore it in use on a parallel mix bus, and see it put to use as a de-esser on a female vocal track.
More On The McDSP AE400 Active EQ
The AE400 is made up of 4 bands of fixed and active equalisation. Each band is completely overlapping with all other bands and has its own Q (bandwidth), fixed gain, and active gain controls. A key filter for each band 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 input signal level sensitivity to further articulate how the active EQ will reach maximum active equalization – a feature unique to the AE400.
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 band dynamics plots. Input and Output controls, individual band bypass, band control linking, and band key signal monitoring round out the features of the AE400.
