Modular
Lowpass Filter
Manual cutoff frequency control for the 12db lowpass filter at the end of the BBD
stage. This control knob may be useful to reduce noise and for sound control.
Delay Time CV Input 1 manual control for the signal level of a delay time CV (Control Voltage)
signal applied on socket T Cvin 1 .
Feedback CV Input manual control (Polarizer) Adjusts the level of feedback CV (Control Voltage)
for a feedback CV signal input applied on socket Feedback CVin . In center position (denter
locked) the input level is 0. Turning this knob clockwise, the incoming feedback CV signal will be
normally added to the feedback control signal adjusted with knob . By turning the knob ccw, the
polarity of the CV signal becomes inverted resulting in a substraction/attenuation of the feedback
control voltage.
Note: The polarizing denter knob is a new feature of Rev.3 of the Delay1022.
Feedback:
Manual control of feedback. The delay output is fed back into the BBD input via an
internal VCA (Voltage Controlled Amplifier). The feedback VCA can be manually controlled with this
knob and/or by adding a control voltage to the feedback CV input . From 5-6 on the scale the
delay begins to self-oscillate.
Delay Time CV Inversion Switch Inverts the incoming signal on socket 'T CVin 1' .
Note: If you are using a delay time CV input (non inverted) for delay time/ frequency modulation,
the feedback sustain may be linearized for different delay times by splitting the T CVin signal and
putting a small amount of this CV into the Feedback CV input. The output level of the BBDs is not
constant over the whole delay time range, though the feedback sustain is not linear for different
delay times; e.g., with the same setting of feedback controls, for a short delay time the tone fades
away; while a longer delay time (or lower frequency) will cause a feedback oscillation. By increasing
the feedback level for higher frequencies by adding a proportional CV to this input this problem can
be minimized.
Feedback CV Input
Control voltage input for the feedback amplification. Its amount can be
adjusted by using the Feedback CV in knob . A positive input voltage will increase the feedback;
a negative voltage will – in combination with manual control knob 'Feedback' - attenuate or mute
the feedback.
Delay Output

delay output is behind the internal feedback VCA. Unlike output 'Mix'

, the
output level is directly dependent of the settings of knob 'feedback' and/or the input on socket
'feedback CV in' ; e.g. if the 'feedback' knob is set on '0' on scale (fully ccw), there will be no
output signal. This muting option can be useful to reduce noise and/or for sound modelling.
