instruction

)
Quatro Figaro is a 4 channel VCA. Channels A, B, C ,D are
organized in columns. Each channel has a gain knob with
a maximum gain of a little over 2.
)
Each CV input has an attenuator. The gain of the vca is
linear to the control voltage on each channel. The final
control voltage is the GAIN voltage + the attenuated CV
IN voltage.
)

Internal routing

Internal routing enables you to use the QF as a simple
and powerful panning tool. Two input pairs (A+B and
C+D) are internally routed via the jack switches, which
enables you to quickly setup a panning situation.
Because the internal routing is via the connector
switches, you can use all the channels independently by
plugging in cables which disconnect the internal routing.
Also the INVERTED CV OUT of channel A is connected to
the switch at the CV IN of channel B (the same with C
and D), which means that the inverted CV is connected
to the CV input of signal B as long as there is no jack
plugged into the signal jack of channel B.
)
For each CV there is an inverted output (not affected by
the attenuator).
)
the signal from channel A is routed to the switch at the
signal jack of channel B (the same with C and D), which
means that the signal from channel A is connected to
channel B as long as there is no jack plugged into the
signal jack of channel B.
)
Signal input goes thru the the VCA and is outputed to
signal out with gain linear to the CV.
)

Mixed outputs

The mixed outputs enable you to use QF as a voltage
controlled mixer or voltage controlled stereo panning
mixer. There are outputs of signal A mixed with signal
C, signal B mixed with signal D (note that these two
outputs are inverted), A+B+C+D mixed together and its
inverted version
