Doepfer A-143-9 VC Quadrature LFO
- Order number: 120133
- Depth: 50
Voltage controlled sine-LFO with four separate, phase shifted outputs: 0° (sine), 90° (cosine), 180° (inverted sine) and 270° (inverted cosine). Suitable for FM, cross-fadings, modulations in opposite directions or applications, where a pure sine is needed like oscillator for a frequency shifter.
The frequency can be set with two CVs, a potentiometer and a three-position switch.
The frequency ranges are as follows:
- switch position H: ca. 30 Hz to 3.5 kHz (up to over 20 kHz via CV)
- switch position M: ca. 1 Hz to 150 Hz
- switch position L: ca. 0.1 Hz to 10 Hz (up to several minutes via CV)

WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
