ons would cause clipping for all standard
A-100 signals (like LFOs, ADSRs or VCOs).
If the amplification is negative the signal is inverted
(see table above).
The effects of the manual control 3 and the external
control voltage ! with attenuator 2 are added up.
4. In- / Outputs
!
CV
This jack socket is the control voltage input to control
the amplification by an external control signal.
"
In
The signal to be amplified/inverted (control voltage or
audio) is fed into this signal input socket ".
§
Out
Socket § is the signal output.
5. User examples
One application is the generation of new waveforms.
For this two VCO outputs are connected to the signal
and the control input of the A-133 (see fig.1).
Fig. 1: Generating new waveforms
Same applies for modulations (see fig. 2). Instead of
LFOs even ADSRs or other CV sources can be used.

polarity changes
Additional examples:
• voltage controlled feedback of filters (e.g. A-108),
phaser (A-101-3) or spring reverb (A-199)
• polarity change of envelope signals (frequency CV
is used to control both filter frequency and polarizer
amplification simultaneously)
