Voltage Controlled Low Frequency Oscillator

The A-147 is a voltage controlled low frequency oscillator which can produce cyclic control voltages over a 0.01Hz to 50Hz range.


The VCLFO can be patched as a modulation such as pulse width, frequency modulation of a VCO (vibrato), modulation of a VCF cut-off frequency, amplitude modulation of the VCA (Tremolo) and as a provider of repetitive or clock voltages (such as for the A-161 clock sequencer).


Four waveforms are available: Triangle, Sine, Square and falling Sawtooth waves. The VCLFO’s frequency can be controlled manually but also by a control voltage.


The VCLFO can be synced to another waveform by connecting the other waveform (e.g another LFO) to the VCLFO’s reset input.
