Quad Inverter Manual
Operation
Intellijel’s Quad Inverter contains four voltage inverters [A - D] — each with an
input jack [1] on top and an output jack [2] beneath it. Each output is a buffered
inversion of the input signal. For example, if you send +3V DC to the input jack,
the inverted output will be -3V DC.
Similarly, if you send a waveform to an input, the output will be an inverted copy
of that waveform. This is particularly useful when you want a control voltage
(such as an LFO or envelope) to inversely impact the parameter it’s modulating.
The output of each inverter is normalled to the inverter immediately below it. So if
you patch a signal into Inverter A and patch nothing into InverterB, then the
signal is passed through from the output of A to the input of B, where it’s inverted
(again), making it identical to the signal appearing at the input of InverterA.
Similarly, if you also leave the InverterC input open, then the input to InverterA
is inverted a third time, making the output of InverterC identical to the output of
InverterA.
NOTE: Quad Inverter does not function as a stand-alone gate inverter (since
inverting a gate is not actually the same thing as inverting a voltage). For this you
need a logic inverter, such as the Intellijel Plog. You may, however, feed an output
from a Quad Inverter into a Triatt or Quadratt to offset the voltage such that gate
inversion occurs.
