Module A-143-3 Quad LFO is a low-cost four-fold modulation oscillator and includes four independent low frequency oscillators (LFO's), which produce cyclical control voltages in a wide frequency range.
Three waveforms are available for each LFO: triangle, square and sawtooth. The frequency of the sawtooth output is twice the frequency of the other outputs.
The LFO's can be used as modulation sources for any control voltage input of other modules - for instance modulating the pulse width or frequency of a VCO, modulating the cut-off frequency of a VCF or the phase-shift of a VCP, amplitude modulation with a VCA, delay time of a BBD module, parameters of a voltage controlled wave shaper/multiplier, or any other control voltage input.
A three-way switch let’s you select three frequency ranges, spanning from about two cycles per minute at the lowest, to moderate audio frequency at the highest. The module includes four identical units.
