Matching Modulation Voltages - Use the IOU's 1x / 2x Gain switch to amplify modulation
sources that output lower peak voltages. For instance, to modify a +5V peak modulation
source to match a module requiring a +10V peak for full modulation range, proceed as
follows:
Patch the +5V peak modulation source into the IOU's input. Select the 2x position on the
Gain Switch to double the modulation voltage. Ensure the DC Offset Slider is at its minimum
setting, if no additional offset is needed. Rotate the Scale knob fully CW to pass the signal
without any attenuation, unless specific scaling is required for modules expecting other
voltage ranges.
Note: Beyond matching voltage levels, the amplification capability of IOU can be used
creatively for audio processing. Utilising the 2x gain setting with audio signals can drive
other modules into more pronounced saturation and distortion, perfect for experimental
sound design. Similarly, when working with wavefolders, a stronger input signal from IOU
can yield more intense and complex wavefolding effects.
