8-Pole Filter Section
The 8-Pole Filter effect structure comprises four 4-pole filters: each stereo channel has a 4-
pole low pass filter and a 4-pole high pass filter. The cutoff frequencies of the low pass and
high pass filters are offset from a reference cutoff frequency. This offset is controlled by the
GAP
parameter. Since the two filters are running in parallel and their output signals are mixed,
the result of a positive
GAP
value is a band rejection. With a negative
GAP
value the pass
bands of both filters are overlapping so that all frequencies can pass and the resonances em
phasize the cutoff frequencies. The difference between the reference cutoff frequencies of the
two channels is controlled by the
L / R
parameter. The
CENTER
parameter is used to set the
mean value of the cutoff frequencies of the two channels.
