A Manual cutoff frequency control
Controls the frequency at which spectral components of the input signal become at-
tenuated.
B Cutoff CV multiplier (bipolar)
Adjusts the level of incoming control voltages on input CV1, applied to the cutoff fre-
quency parameter. This is a bipolar multiplier. The 12 oʼclock setting stands for zero. Values
counterclockwise of this point invert the control voltage, while clockwise settings do not.
C Cutoff CV input 1
Accepts a control voltage for modification of the filterʼs cutoff frequency. Governed by
the adjoining multiplier control.
D Cutoff CV input 2
An additional input for control of cutoff frequency. Very sensitive!
E Manual resonance control
Controls the amount of feedback within the filter circuit, which emphasizes the parts
of the spectrum near the cutoff frequency. At high settings the filter will self-oscillate, but this is
very unstable and heavily dependent on the amplitude and other characteristics of the input
signals.
F Audio input 1
Insert an audio signal here.
G Audio input 1
Insert another audio signal here.
H Input 1 attenuator
This controls the level of the signal present at Input 1. Note that "hot" mixes can reveal
the characteristic Polivoks distortion, especially at higher resonances.
I Input 2 attenuator
This controls the level of the signal present at Input 2.
J Low pass output
This output presents the filtered signal, with frequencies _above_ the cutoff frequency
attenuated at 12db/octave.
K Band pass output
This output presents the filtered signal, with frequencies _above_ and _below_ the cut-
off frequency attenuated at 6db/octave.
