Behringer 112 Dual VCO Eurorack Module

Behringer 112 Dual VCO is an analog Eurorack synthesizer module designed for modular synthesis systems and studio environments. It enables voltage-controlled sound generation using two independent oscillators for musicians and sound designers, supporting oscillator-based synthesis workflows. This makes it ideal for modular systems where multiple synchronized or layered oscillators are required.

The module operates with two discrete voltage-controlled oscillators that can function independently or be synchronized using selectable sync modes. Control voltage and pulse width modulation inputs allow external sources to influence pitch, waveform shape, and phase behavior. Audio and control signals are routed through dedicated front-panel inputs and outputs for integration with other modules.

This configuration supports building complex oscillator interactions within a compact Eurorack footprint. It can be used for harmonic layering, modulation routing, and oscillator synchronization tasks. The module conforms to standard Eurorack power and mounting requirements.

Key Features

• Dual Oscillator Design: Two independent voltage-controlled oscillators in one module
• System 100M Circuitry: Authentic reproduction of original System 100M oscillator design
• Waveform Selection: Triangle sawtooth and pulse waveforms available on each VCO
• Pulse Width Modulation: Manual and external CV control of pulse width
• Oscillator Sync: Selectable weak and strong sync modes for phase locking
• Extensive Control Access: Eighteen front-panel controls and switches for real-time adjustment
