Doepfer A-137-2 Wave Multiplier II Waveshaper Module

The Doepfer A-137-2 Eurorack Wave Multiplier Module is a Eurorack wave multiplier module, that adds 4 phase-shifted VCO signals to audio input. A module A-137-2 is another version of a wave multiplier. In contrast to the A-137-1 Wavemultiplier I the A-137-2 generates four phase-shifted copies of a VCO signal applied to the audio input. The four shifted signals are added to the original signal to obtain a fat sound similar to five independent VCOs. The phase shifting is made by a simple circuit that works only for sloped signals like sawtooth, triangle or sine, but not for rectangles or pulses.

The main features of the Doepfer A-137-2 Eurorack Wave Multiplier Module include:

• Wave multiplier module
• Adds 4 phase-shifted VCO signals to audio input
• Width: 14HP, 70.8mm
• Depth: 50mm
• Current drain: 30mA
