positive clipping control

CL–:

negative clipping control

This controls are used to adjust the upper and lower clipping
levels of the filter circuit. At the left position the smallest
clipping level is chosen, i.e. clipping appears even at small
input levels. Turning a clipping control clockwise increases
the clipping level and clipping occurs just at higher levels.
The adjustment of the clipping controls also affects the max.
output level as for higher clipping levels even the max.
output level becomes higher.
The module is prepared to control the clipping functions with
voltages by using the universal vactrol module A-101-9. For
details please refer to page 7 and the A-101-9 user's
manual.

resonance level control

This group of elements is responsible for the resonance
functions of the module. Socket / is the input of the
resonance loop and is normalled to resonance output socket
&

. If an external module is used to control the resonance

loop (e.g. a VCA), this module has to be inserted between
socket & and socket /. The resonance control 8 is used to
adjust the resonance level manually. Resonance can be
increased up to self-oscillation. As already mentioned in
chapter 2 the controls for level, resonance and clipping

influence each other. E.g. the waveform generated in self-
oscillation mode depends upon the settings of the clipping
controls and the resonance, or self-oscillation is reduced or
even "killed" by an excessive audio level.
