Crossfader (Unipolar CV)
To use AMPS as a crossfader with a unipolar CV
input that crossfades between two incoming
waveforms.
1. Set the CV A POLARITY [G] switch to — , and the
CV A attenuator [C] fully clockwise.
2. Set the CV B POLARITY [H] switch to + , and the
CV B attenuator [D] fully clockwise.
3. Set the VCA B PHASE INVERT [K] switch to the
DOWN (in-phase) position.
4. Set the VCA A LEVEL [A] at the top, and set
VCA B LEVEL [B] at the bottom.
5. Patch external waveform 1 into IN A [3] .
6. Patch external waveform 2 into IN B [4] .
7. Patch OUT B [6] into an external VCA or mixer.
8. Patch a unipolar control voltage into CV A IN [1] ,
and vary it.
Sweeping the control voltage from 0V to +5V will
crossfade external waveform 1 with external
waveform 2.
That is, positive voltages increase the amount of
external waveform 2 present at OUT B [6] while
simultaneously decreasing the amount of external
waveform 1.
