Behringer MODAMP MODULE 1005 Eurorack Ring Modulator

The Behringer MODAMP MODULE 1005 is an analog Eurorack module that faithfully recreates the legendary ModAmp from the original 2500 Series synthesizer of the 1970s. At its heart is a discrete balanced modulator that accepts two input signals — anywhere from DC to 20 kHz — and produces an output that is the mathematical multiplication of those signals. This multiplication generates sum and difference frequencies that result in the complex, inharmonic overtones characteristic of ring modulation: metallic clangs, bell-like tones, and otherworldly textures that have defined experimental electronic music for decades.

In addition to the balanced modulator, the module includes a dedicated voltage-controlled amplifier (VCA), giving you two essential synthesis building blocks in a single panel. The all-analog, discrete component design means the module responds with the warmth, character, and subtle nonlinearities of the original hardware rather than a digital approximation. Whether you are using it to create evolving drones by modulating two oscillators against each other, processing external audio for aggressive timbral effects, or using sub-audio signals to generate complex control voltages, the MODAMP MODULE 1005 brings a piece of classic synthesis history into the modern Eurorack ecosystem at an accessible price point.
