Modular Synthesizer Module Behringer 150 RING MOD — Ring Modulator / Noise / LFO

Behringer 150 RING MOD — Ring Modulator / Noise / LFO is a Eurorack-format modular synthesizer module that combines classic ring modulation with onboard noise generation and a low-frequency oscillator. The unit processes audio and control signals to produce inharmonic textures, metallic timbres, tremolo and clocking effects. Designed for integration into modular rigs, it supports sound design and experimental synthesis workflows where modulation, cross-modulation and noise sources are required.

Advantages

The module integrates three functions—ring modulation, noise source and LFO—into a single compact Eurorack module, reducing the need for multiple modules. Its ring modulator produces complex, inharmonic sidebands when two signals are combined, while the built-in noise generator provides a steady source for percussive and texture layers. The included LFO offers a controllable modulation source for amplitude and rate-based effects. The front-panel controls allow direct, hands-on adjustment of modulation depth, noise level and LFO rate for immediate sound shaping.

Suitable for

• Modular synthesizer rigs and Eurorack systems
• Sound design for electronic music, film and games
• Experimental synthesis and noise-based textures
• Creating tremolo, gated and metallic timbres
• Audio cross-modulation and ring-modulated effects

Key specifications

• Functions: ring modulation, analog noise source, low-frequency oscillator (LFO)
• Format: Eurorack-compatible module size and power requirements
• Controls: front-panel knobs for modulation depth, noise level and LFO rate
• Inputs/Outputs: audio and CV inputs for source signals and modulation, audio output for processed signal
• Signal types: processes audio-frequency signals and control voltages for modulation

How to use

Patch an audio source and a carrier signal into the module's designated inputs, adjust the modulation depth control to blend the ring-modulated output, and route the processed signal to a mixer or next module. Use the noise output as an independent sound source or mix it with the carrier to add texture. Apply the onboard LFO to amplitude or rate parameters via the CV input to create tremolo, rhythmic gating or cycling modulation. Adjust LFO rate and depth to synchronize or evolve effects within a patch.

Usage recommendations

For best results, use the module within a properly powered Eurorack case and normalize levels to avoid clipping. Combine the ring modulator with filters, envelopes and VCAs to sculpt noisy or metallic tones into usable musical elements, and experiment with cross-patching multiple signals for complex inharmonic textures.
