Adds Harmonic Content to Oscillators and Control Signals

Use the Doepfer A-137-1 Eurorack Voltage-Controlled Wave Multiplier module to add harmonic complexity to any signal in your Eurorack rig — audio or control voltage. Whether you use it to add harmonics to an oscillator or complexity to an LFO signal, the A-137-1 module multiplies the incoming waveform without changing its pitch or frequency. That means you can add richness and complexity to sound sources and turn ordinary modulation signals into something much more animated and evocative. Eurorack fans at Sweetwater recommend using this module on waveforms with low harmonic content, like sine and triangle waves. But however you use it, the Doepfer A-137-1 wave multiplier opens up entirely new possibilities with your existing Eurorack modules.

Doepfer A-137-1 Eurorack Voltage-Controlled Wave Multiplier Module Features:

  • Wave multiplier module adds harmonic content to audio and control signals
  • Multiplies incoming waveform without changing its pitch or frequency
  • Perfect for waveforms with low harmonics, such as sine and triangle waves
  • Multiples parameter controls the number of wave multiplications per cycle
  • Harmonics parameter highlights harmonic content, similar to the Resonance control on a filter
  • Attenuators on all inputs to help maintain proper signal level
  • Size: 14HP, 65mm deep
  • Power usage: +40mA (+12V)/-20mA (-12V)
