Signal scaling, inversion and voltage offset tool from Apollo View Modular

The IOU from Apollo View Modular is a very practical single-channel tool for signal scaling, inversion and voltage offset. To help weak signals get back on their feet or to make a signal adjustment for modules with a voltage range of 10V, the input gain can be switched from x1 (same voltage) to x2 (double voltage). Unique for an attenuator is the possibility to apply the offset either before or after the attenuator. In the setting PRE , IOU enables detailed, granular offsets over the entire slider range. At POST , the Offset acts as you would expect. When no cable is connected to the input, the module acts as a fixed voltage generator with an adjustable voltage range of +/- 10 volts, depending on the switch position.
