hello ingo-2,
the a136 is a great module just needs the correct
settings: its A knob amplifies the signal with a gain
rate of about 4 to 5. so, in order to obtain a neutral
signal you have to set the A knob to about +1(gain to
about 1). the same is valid for the +A and -A knobs.
also the +L and -L knobs define the upper and lower
limits for the clipping. so to obtain neutral results
for these two knobs you have to set the +l knob to
-5(i think they are reverse...) and -L to +5. that way
you have an unclipped and unamplified waveform. then
you start from there. the magic is to make small
moves...(as they said in the Carl Sagan film
"Contact").
bakis.
