Product information "Doepfer A-145-4 Quad LFO Slim Line"
Doepfer's new A-145-4 is a quad LFO with rectangular and triangular waveforms.
Module A-145-4 is a simple quad LFO (Low Frequency Oscillator). Not a very "exciting" module, just a bread-and-butter device and a simple demon for work. Virtually in every modular system several LFOs are required for modulation purposes. The module contains four simple LFOs with the waveforms triangle and rectangle.
A dual color LED (red = positive / yellow = negative output voltage) indicates the triangle output of each LFO.
The frequency range can be chosen for each LFO individually by means of a jumper between about 50 Hz ... 0,04 Hz (about 25 seconds, jumper removed) and about 2Hz ... 0,002 Hz (about 8 minutes, jumper installed).

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.
