A*B+C

Befaco

Voltage-Controlled Voltage Processor. Two-channel utility that multiplies two input signals (A × B) and adds a third signal (C) to the result. Supports ring modulation, linear VCA, mixing, attenuation, and CV processing.532

Capabilities 4

Attenuverterattenuverter
The B multiplier stage acts as a CV-controlled bipolar attenuator; the C input adds a DC offset. Supports ring modulation, phase inversion, and attenuation.532
Mixermixer
Each channel sums A×B with the C input, enabling use as a signal mixer.532
Offset Generatoroffset-generator
The C input (normalled to 5V) can act as a DC offset generator.532
Voltage-Controlled Amplifiervca
The A×B multiplier stage functions as a linear VCA when C=0.532
