Behringer System 100 150 Ring Mod/Noise/S&H/LFO, $49!

The Behringer System 100 150 Ring Mod/Noise/S&H/LFO module is a multi-functional Eurorack module inspired by the classic Roland System 100M. This versatile module combines ring modulation, noise generation, sample and hold (S&H), and low-frequency oscillator (LFO) functionalities into a single unit, making it an essential tool for sound designers and modular synthesizer enthusiasts.

Key Features:

Ring Modulator:

  • Ring Modulation: Combines two input signals to create complex, metallic, and bell-like tones. Ideal for creating unique textures and harmonics.
  • Inputs: Two audio inputs for the signals to be ring modulated.
  • Output: Single ring-modulated output.

Noise Generator:

  • White and Pink Noise: Provides both white and pink noise outputs, useful for creating percussive sounds, effects, and adding texture to patches.

Sample and Hold (S&H):

  • Sample and Hold Circuit: Samples the voltage of an input signal and holds it until the next trigger, creating stepped, random voltages.
  • Inputs: Signal input and trigger input for sampling.
  • Output: Stepped output based on the sampled signal.

Low-Frequency Oscillator (LFO):

  • LFO with Multiple Waveforms: Provides triangle and square wave outputs for modulation purposes.
  • Frequency Control: Knob to adjust the LFO rate, enabling slow to fast modulation cycles.

Sound Characteristics:

  • Complex Modulation: The ring modulator and S&H circuits allow for the creation of complex, evolving modulations and textures.
  • Versatile Noise: The white and pink noise outputs can be used to create a variety of percussive sounds and background textures.
  • Dynamic Modulation: The LFO adds dynamic movement to patches, capable of modulating various parameters within a modular setup.


  • Sound Design: Ideal for creating unique soundscapes, effects, and textures with its combination of ring modulation, noise generation, S&H, and LFO functionalities.
  • Modular Synthesis: Perfect for modular synth enthusiasts who need versatile modulation and sound shaping tools in one module.
  • Live Performance: Suitable for live performances, offering hands-on control over multiple sound generation and modulation parameters.
