Quad Voltage Controlled Low Frequecy Oscillator /VCO
The A-143.4 is a fourfold voltage controlled low frequency oscillator, though as it is switchable to a range covering up to 15KHz, can be considered an audio VCO as well.
Each LFO/VCO is independent with frequency control, modulation depth and Triangle and Square outputs. A reset input allows the wave cycle to be reset to zero. LFO 4 has an extra reset for Up or Down direction.
A common CV input and frequency control, control are 4 units at once.
The LFO range goes from 0.001Hz (about 1 cycle per hour ! with ultra low option) upto 15KHz (in VCO mode)
LED indictaor are bi-coloured to show polarity of the LFO cycle.
