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.
