1 Input Level
Attenuator 1 adjusts the level of the audio input signal
applied to the audio input socket !. The attenuated
signal is fed to each of the four resonance filters.
H The audio inputs of the filters are very sensitive
so that distortion - even with normal A-100
audio levels (e.g. VCO A-110) - may intentio-
nally be used to create new sounds. Distortion
appears about from the middle position of the
input level control 1.
