Doepfer A-111-4 Quad VCO

Immerhin ist der A-111-4 sehr ähnlich wie vier A-111-3 ohne LFO-Modus, aber mit Ausgangsmischern für die drei Wellenformen und einer Mastereinheit für alle vier VCOs ausgestattet. Controls, inputs and outputs for each of the four VCOs: 1V/Octave CV input Octave switch ( 1 / 0 / -1 octave) Tune control (range internally adjustable by jumpers: ~ 2 semitones / ~ 1 octave / ~ 4 octaves) Modulation CV input Modulation destination: upper position: exponential frequency modulation (XM) lower position: linear frequency modulation (LM) or pulsewidth modulation of the rectangle (PM), selectable via internal jumper Frequency Modulation (FM) or Pulsewidth Modulation of the rectangle (PWM) Modulation intensity Triangle output Sawtooth output Rectangle output (about 50% without external PWM) Sync input (hard or soft sync internally selectable via jumper, CEM3340 hard sync type) min. 10 Oktaven Bereich (mit entsprechender externer CV) CEM3340 based VCO (triangle core) each VCO has its own separate internal /- power supply for each for best stability and the prevention of unwanted synchronization of the VCOs Controls, inputs and outputs of the master section: 1V/Octave CV input Octave switch ( 1 / 0 / -1 octave) Tune control (range internally adjustable by jumpers: 2 Semitone / 1 Oktave / 4 Oktaven) Frequency Modulation CV input (FM) FM intensity Triangle sum output Sawtooth sum output Rectangle sum output soon as 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 by means of solder brigdes on the pc board, d.h. diese Funktion kann für jede einzelne Ausgangsbuchse ausgeschaltet werden.e. Die Summe enthält dann alle Signale unabhängig vom Patching des einzelnen Ausgangs) CV-Ausgang (gibt die CV-Summe aus, die zur Steuerung aller vier VCOs verwendet wird) CV-Bus (über Jumper auswählbar) Typische Anwendungen: fat sounding monophonic VCOs with the possibility to adjust any intervals paraphonic patches in combination with the polyphonic CV interface A-190-5 (all four VCOs processed by one VCF/VCA) full polyphonic patches in combination with the polyphonic CV interface A-190-5 and four complete VCF/VCA sections complex VCO patches with up to four VCOs by means of the frequency modulation features (exponential an linear) and the sync functions Power consumption: 120mA at 12V and 100mA at -12V Depth: 40mm
