Behringer 150 RING MOD/NOISE/S&H/LFO - Eurorack Modular Synthesizer Module

The Behringer 150 RING MOD/NOISE/S&H/LFO is a versatile Eurorack modular synthesizer module, serving as a faithful reproduction of the legendary System 100M circuits from the 1980s. It combines four essential functions—ring modulation, noise generation, a Sample and Hold circuit, and a Low-Frequency Oscillator (LFO)—offering vast sound-shaping possibilities in a single, compact module ready for immediate integration into your modular system.

Product Features

The module stands out with the following features: analog ring modulation for generating metallic and bell-like tones, noise generator providing white and pink noise, Sample and Hold circuit with clock frequency and delay control, LFO with five waveforms—sine, triangle, square, ramp, and sawtooth, three-position switch allowing signal source selection, and Eurorack compatibility ensuring easy integration with existing modular systems.

Professional Tools for Sound Experimentation

Thanks to ring modulation, this module allows you to create unique, metallic, and bell-like sounds that can be layered onto any input signal—from a sine wave to a signal derived from an LFO. The signal is input via the EXT SIG X/NOISE and EXT SIG Y/LFO jacks, while the processed sound exits through the RING MOD output. This is an ideal solution for creating experimental sounds that will enrich any composition, from electronic music to experimental soundscapes.

The LFO offers five different waveforms—sine, triangle, square, ramp, and sawtooth—providing immense flexibility in parameter modulation. LFO parameters can be precisely adjusted using the FREQ and DELAY sliders, enabling control over frequency and modulation start delay. Additionally, the module features a phase lock, which allows synchronization of the LFO with keyboard playing, ensuring precise and repeatable modulation effects. The dual LFOs offer a wide frequency range and a CV input for external control.

The Sample and Hold (S&H) circuit is another powerful feature of this module. It allows sampling any external signal and holding its value, which is ideal for layering tracks on droning notes or creating atmospheric ambient effects. The three-position switch enables selection of the signal source fed into the S&H circuit—it can be an external input, the LFO, or the noise generator. Control over clock frequency and delay time provides full control over the rhythm and character of the sampling, allowing precise adjustment of the effect to suit the needs of the composition.

The module is fully compatible with the Eurorack format and can be easily mounted in a standard case. Simply connect the power cables to the power supply and secure the module using the included screws. This allows you to freely mix it with other modular synthesizer modules, creating a fully personalized sound configuration. Whether you are just starting your journey with modular synthesizers or looking to expand your existing setup, this module will be an invaluable tool in your studio.
