Behringer System 100 112 Dual VCO, $79!

The Behringer System 100 112 Dual VCO (Voltage Controlled Oscillator) module is part of Behringer’s Eurorack series inspired by the classic Roland System 100M. The 112 module offers two fully-featured oscillators, each capable of generating a variety of waveforms with precise control over pitch and modulation. This module is designed for synthesizer enthusiasts looking for high-quality, vintage-inspired oscillators to add to their modular systems.

Key Features:

Dual VCO:

  • Two Independent Oscillators: The 112 module includes two separate VCOs, each with its own set of controls and outputs, providing flexibility and versatility in sound design.
  • Waveform Selection: Each oscillator can produce four waveforms: sawtooth, square, triangle, and pulse, allowing for a wide range of timbres.

Pitch and Tuning Control:

  • Coarse and Fine Tuning: Both VCOs feature coarse and fine tuning knobs, enabling precise control over the pitch and making it easy to dial in exact frequencies.
  • Octave Selector: Switches to quickly shift the pitch of each oscillator up or down by one or more octaves.

Modulation Options:

  • Pulse Width Modulation (PWM): The square wave output of each oscillator can be modulated using PWM, adding dynamic movement to the sound.
  • Frequency Modulation (FM): Each VCO has an FM input for frequency modulation, allowing complex and evolving timbral changes.

Inputs and Outputs:

  • Multiple CV Inputs: Includes several CV inputs for pitch and modulation control, providing extensive patching capabilities.
  • Waveform Outputs: Dedicated outputs for each waveform type, allowing users to mix and match waveforms from both oscillators.

Sound Characteristics:

  • Rich Analog Tone: The 112 module delivers the warm, rich tones characteristic of vintage analog synthesizers, making it ideal for creating classic synth sounds.
  • Versatile Sound Design: Capable of producing a wide range of sounds, from smooth and mellow to bright and aggressive, depending on the waveform and modulation settings.


  • Sound Design: Perfect for sound designers looking to create unique and complex sounds with rich harmonic content.
  • Modular Synthesis: An essential addition to any Eurorack system, providing the foundational sound generation needed for synthesis.
  • Live Performance: Suitable for live performances, offering reliable and high-quality sound with extensive modulation options.


  • Width: 16 HP
  • Depth: 50 mm
  • Power Consumption: 70 mA (+12V), 40 mA (-12V)
  • Inputs: Multiple CV inputs for pitch, PWM, and FM
