The A-147-2 is a classic for a reason – it's a surprisingly versatile modulation source. It’s fantastic for adding subtle movement or chaotic textures to your synths, and the ring modulator is a real bonus for experimental sound design. Ideal for anyone building a Eurorack system and wanting a workhorse LFO with a bit of extra character.

Product Description

  • Doepfer A-147-2 VCD LFO
  • Voltage Controlled Delayed Low Frequency Oscillator
  • Module consists of a voltage-controlled low frequency oscillator (LFO) and a voltage controlled amplifier (VCA)
  • Switchable to polarizer / ring modulator
  • and voltage-controlled linear delay envelope (only one parameter: Delay or Attack) for delayed LFO operation with voltage control
  • Width: 8 HP
  • Depth: 55 mm
  • Power requirement: +60 mA (+12 V) / -40 mA (-12 V)
  • Width: 8 HP
  • Depth: 55 mm
  • Power requirement: +60 mA (+12 V) / -40 mA (-12 V)
PROS
  • • Versatile modulation options beyond standard LFO behavior
  • • Ring modulation function adds unique sonic textures
  • • Compact 8HP footprint optimizes modular space
  • • Robust Doepfer build quality ensures long-term reliability
CONS
  • • Limited waveform selection compared to more modern LFOs
  • • Delay/Attack parameter lacks finer control for precise envelopes
  • • Power consumption is relatively high for a single module

Frequently Asked Questions

The 'delay' parameter acts as an attack time for the LFO, creating a delayed rise. This is useful for creating rhythmic pulses or subtly phasing effects.
The ring modulation output is generally clean, but it can exhibit a slight hum, typical of analog ring modulation. It's easily manageable with proper grounding and gain staging.
While it lacks the extensive waveform options of some modern LFOs, the A-147-2 offers a classic, reliable character and a unique ring modulation feature that many newer modules lack.
