8-Pole Filter Section - Native Instruments Reaktor Spark Manual

4.7 8-Pole Filter Section

With the 8-pole Filter you can filter the overall signal before it reaches the instrument output.
The 8-Pole Filter effect comprises four 4-pole filters: each stereo channel has a 4-pole lowpass
filter and a 4-pole highpass filter. The cutoff frequencies of the lowpass and highpass filters
are offset from a reference cutoff frequency. This offset is controlled by the g K . Since
ap nob
the two filters are running in parallel and their output signals are mixed, the result of a positive
Gap is a band rejection. With a negative Gap the pass bands of both filters are overlapping
so that all frequencies can pass and the resonances emphasize the cutoff frequencies. The
difference between the reference cutoff frequencies of the two channels is controlled by the
lr o K . The c K is used to set the mean value of the cutoff frequencies of

the two channels.
