After all the A-111-4 is very similar to four A-111-3 without LFO mode but built in output mixers for the three waveforms, and a master unit for all four VCOs.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eControls, inputs and outputs for each of the four VCOs: \u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e1V\/Octave CV input\u003c\/li\u003e \u003cli\u003eOctave switch (+1 \/ 0 \/ -1 octave)\u003c\/li\u003e \u003cli\u003eTune control (range internally adjustable by jumpers: ~ 2 semitones \/ ~ 1 octave \/ ~ 4 octaves)  \u003c\/li\u003e \u003cli\u003eModulation CV input\u003c\/li\u003e \u003cli\u003eModulation destination: \u003cul\u003e \u003cli\u003eupper position: exponential frequency modulation (XM)\u003c\/li\u003e \u003cli\u003elower position: linear  frequency modulation (LM) \u003cu\u003eor\u003c\/u\u003e pulsewidth modulation of the rectangle (PM), selectable via internal jumper\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003cli\u003e Frequency Modulation (FM) or Pulsewidth Modulation of the rectangle (PWM)\u003c\/li\u003e \u003cli\u003eModulation intensity\u003c\/li\u003e \u003cli\u003eTriangle output\u003c\/li\u003e \u003cli\u003eSawtooth output\u003c\/li\u003e \u003cli\u003eRectangle output (about 50% without external PWM)\u003c\/li\u003e \u003cli\u003eSync input (hard or soft sync internally selectable via jumper, CEM3340 hard sync type)\u003c\/li\u003e \u003cli\u003emin. 10 octaves range (with appropriate external CV)\u003c\/li\u003e \u003cli\u003eCEM3340 based VCO (triangle core)\u003c\/li\u003e \u003cli\u003eeach VCO has it's own separate internal +\/- power supply for each for best stability and the prevention of unwanted synchronisation of the VCOs\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eControls, inputs and outputs of the master section:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e1V\/Octave CV input\u003c\/li\u003e \u003cli\u003eOctave switch (+1 \/ 0 \/ -1 octave)\u003c\/li\u003e \u003cli\u003eTune control (range internally adjustable by jumpers: 2 semitones \/ 1 octave \/ 4 octaves)  \u003c\/li\u003e \u003cli\u003eFrequency Modulation CV input (FM)\u003c\/li\u003e \u003cli\u003eFM intensity\u003c\/li\u003e \u003cli\u003eTriangle sum output\u003c\/li\u003e \u003cli\u003eSawtooth sum output\u003c\/li\u003e \u003cli\u003eRectangle sum output\u003c\/li\u003e \u003cli\u003eas soon as the single waveform output of a VCO is patched this waveform of the VCO in question is removed from the sum (this function can be turned off for each single output socket by means of solder brigdes on the pc board, i.e. the sum contains then all signals independent of the patching of the single output)\u003c\/li\u003e \u003cli\u003eCV output (outputs the sum CV that is used to control all four VCOs)\u003c\/li\u003e \u003cli\u003ebus CV (via jumper, optional, please remove the bus jumper if this feature is not used to avoid unwanted frequency modulation as then the unused CV line of the bus works as a kind of antenna)\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cu\u003eTechnical remarks:\u003cbr\u003e \u003c\/u\u003e\u003cbr\u003e The module is based on the CEM3340 circuit.
