Analogue Modular System A-100
The A-110.2 basic VCO provides 3 simultaneous waveforms, saw tooth, pulse and triangle.
3 position octave shift switch and Tune control (which can be set to a 4 octave or ½ octave range with a pcb jumper)
The pulse width can be varied manually between 0% and 100% or controlled via by it’s pulse width CV input, with a variable depth control.
Pitch modulation is by 1V/Oct which is normally connected to the keyboard CV, and normalised to the bus board CV line (can be disconnected from the bus with a pcb jumper)
Exponential FM input with a depth control.
Linear FM input.
Oscillator sync is provided in the form of hard and soft sync.
The A-110.2 uses reliable temperature compensation circuitry to maintain an accurate stable pitch.
Note:- the current requirement is 150mA for the first 30 seconds of warm up time, then stabilises to the stated 60mA.
