ADVANCED PATCHING IDEAS
Aside from the obvious uses as a dual VCA, the polarity and phase switches provide AMPS with a
couple of additional capabilities, which are often not part of standard VCAs.
Ring Modulator
To use AMPS as a ring modulator:
1. Set the CV A POLARITY [G] switch to + , and the
CV A attenuator [C] fully clockwise.
2. Set the CV B attenuator [D] fully
counterclockwise.
3. Set the VCA B PHASE INVERT [K] switch to the
UP (invert) position.
4. Patch external waveform 1 into IN A [3] .
5. Patch OUT B [6] into an external VCA or mixer.
6. Set the VCA A LEVEL [A] and VCA B LEVEL [B]
to the same height, halfway up the sliders.
When the two sliders are at the same level (and
with nothing patched into CV A IN [1] ) you will
hear no sound from the OUT B [6] jack.
7. Patch external waveform 2 into CV A IN [1] .
OUT B [6] will now carry the ring modulated
output of the waveforms patched into IN A [3] and
CV A IN [1] .
