Befaco's A*B+C is one thing above all: a multifunctional, analog PowerHouse for processing audio and CV signals. The module consists of two channels, each of which takes two input signals (A and B), multiplies them (A × B) and then adds a third signal (C) to the result. In practice, A*B+C offers a whole range of functions that are used in almost every Patch . When processing audio signals, the module acts as a ring modulator, linear VCA, audio mixer, gain amplifier, phase Inverter and attenuator. When applied to control voltages, the module can be used as a voltage-controlled attenuator, CV mixer, bipolar attenuator, inverter, VCA or fixed-voltage generator.
