hello brett,

yes and no.
you have to mix the original signal with the filtered one
in order to get an equalizer. you also have to invert the
filtered signal, if you want to apply cut instead of boost.

so you need a separate highpass and a lowpass filter
(for getting wide q settings without filter-ringing),
a mixer, an inverter, a polarizer, a multiple.
except for the multiple and the mixer, you would need
that for each single eq band. thinking of a four-band eq,
more than a full 3 he frame of modules is needed then.

best wishes

ingo
