With the BM-12 Ring Modulator, Behringer presents a clone of the Moog MF-102 Ring Modulator from the popular MoogerFooger series. Behringer has succeeded in faithfully reproducing the distinctive sound of this classic in every detail. As a ring modulator, the effect imparts a metallic character to any signal you feed into it. Whether it’s a guitar, synth or drum machine, the results are, across the board, quirky, wild and experimental. If you use a microphone at the input, you’ll sound like the Daleks from Doctor Who. The internal oscillator can be replaced by an external signal; so there’s nothing to stop you, for example, from ring-modulating two individual outputs from a drum machine against each other. In Low mode, the effect spectrum shifts towards tremolo. It sounds absolutely brilliant with strings, chords and anything with a long sustain, but here too, experimentation is key! The LFO, with sine or square waveforms, modulates the oscillator’s frequency parameter, instantly producing those iconic effect sounds. The input stage is designed for line and guitar levels and can be overdriven; in most cases, this sounds very musical and has a harmonic character.
The connections are the same as on the original: there are four CV/expression inputs for the parameters Rate, Amount, Mix and Frequency. This allows the parameters to be controlled via an expression pedal or by any control voltages from the modular system. The audio inputs and outputs are mono. Carrier Out routes the sine-wave oscillator to an external device; Carrier In replaces the internal oscillator with an external signal. The sine-wave or square-wave form of the LFO is output via LFO OUT and can thus serve as an additional modulation source for other instruments with a control voltage input.
