Befaco - A*B+C (2025)

The CV-warping module A*B+C returns with a fresh look, and Befaco has even improved it!

A*B+C offers two channels for mixing, multiplying, or attenuating control voltages. Both channels are nearly identical, each featuring three inputs. As the name suggests, these inputs are combined to create a versatile and powerful tool for shaping control voltages.

B and C provide a 5V voltage when their inputs are left unpatched. Compared to its predecessor, the new version also includes gain switch, allowing input voltage to be doubled in amplitude or inverted. In addition to LED indicators that help visualize outputs, all upcoming Befaco modules now feature a redesigned front panel.

A fantastic utility module that works just as well as a dual ring modulator, dual VCA, and four-channel mixer.

Features:

• Two-channel bipolar VCAs
• Adjustable offset per channel
• AM and ring modulation capabilities
• DC-coupled
• Signal LED indicators
• B and C inputs normalized to 5V
