Doepfer - A-143-3: Quad LFO
Module a-143-3 is a low-cost four-fold modulation oscillator, often called lfo (low frequency oscillator). like the other modules of the a-143 series (a-143-1 and a-143-2) not a very "exciting" module, just a bread-and-butter device and a simple demon for work. the module contains four simple lfos. each lfo is equipped with three waveform outputs: triangle, rectangle and sawtooth. the frequency of the sawtooth output is twice the frequency of the other outputs. a three-way switch is used to select one of three frequency ranges mid-low-high, spanning from about two cycles per minute at the lowest, to moderate audio frequency at the highest (about 5 khz).
if other waveforms or additional lfo features are required (e.g. reset input, adjustable waveform, voltage controlled frequency) the lfo modules a-145, a-146 and a-147 are available.
this module has a maximum current draw of 70ma. it requires 14 te/hp worth of space to fit in a eurorack frame.
