User Manual

[F] BOOST B switch - Same as BOOST A [E] switch, but
allows for VCA B amplification in excess of unity gain.
[G] CV A POLARITY switch - inverts the voltage arriving at the
CV A [1] input, so that positive voltages affect the VCA
negatively, and vice versa.
[H] CV B POLARITY switch - inverts the voltage arriving at the
CV B [2] input.
[I] CV A LED - Displays a visual representation of the voltage
currently modulating the VCA A level. This is the voltage
arriving at CV A IN [1] after passing through both the
CV A Attenuator [C] and the CV A Polarity [G] switch.
Positive voltages light the LED green ; negative voltages
light it red . The brighter the LED, the higher the absolute
voltage.
[J] CV B LED - Displays a visual representation of the voltage
currently modulating the VCA B level. This is the voltage
arriving at CV B IN [2] after passing through both the
CV B Attenuator [D] and the CV B Polarity [H] switch.
Positive voltages light the LED green ; negative voltages
light it red . The brighter the LED, the higher the absolute
voltage.
[K] VCA B PHASE INVERT switch - In the UP position, this
inverts the phase of the IN B [4] signal, which (among
other things) allows for ring modulation (see Ring
Modulator , later in this manual).
[L] OUT A LED - Indicates the level and polarity of the signal
present at OUT A [5] . Positive voltages light the LED
green ; negative voltages light it red . The brighter the LED,
the higher the absolute voltage. At audio rates, the LED
appears solid, since the polarity changes too frequently for
the eye to perceive.
[M] OUT B LED - Indicates the level and polarity of the signal
present at OUT B [6] .
