Using signal cancelling with an out-of-phase pass-through, we show how DynPEQ plugins work on an intricate level. Topics include the equivalence of static gain and dynamic gain offset, how to create an inverse of a static DynPEQ band, and inversion techniques for dynamic bands within the same plugin or with another DynPEQ plugin connected in series, and in what cases DynPEQ inversion cannot be made prefect or near-perfect. NOTE: the indicator of cancellation level is on the lower-right corner of the screen, on the master fader.
