Doepfer A-137-1 Wave Multiplier I: Add Harmonic Complexity to Simple Waveforms

The A-137-1 Wave Multiplier I from Doepfer is a fully analog module designed to enrich simple waveforms (like triangle or saw) with dynamic harmonic content. With four shaping controls—multiplication, symmetry, waveform level, and DC offset—it allows for subtle enhancement or wild wave distortion.

Key Features:

• Adds rich harmonic overtones to basic waveforms

• Four manual controls: multiplier, symmetry, level, offset

• 100% analog signal path for natural sound

• Ideal for use with VCOs or external sources

• Perfect for experimental sound design and traditional synthesis

Technical Specifications:

• Width: 8 HP

• Power Consumption: +50 mA / -40 mA

• Inputs: 1x Audio

• Outputs: 1x Processed Audio

• Format: Eurorack (3U)
