Doepfer - A-111-4: Quad Precision VCO

Manufacturer Description: A-111-4 contains four precision VCOs and has individual controls, inputs and outputs for each VCO available as well as a common control and output unit. 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.Controls, inputs and outputs for each of the four VCOs:1V/Octave CV inputOctave switch (+1 / 0 / -1 octave)Tune control (range internally adjustable by jumpers: ~ 2 semitones / ~ 1 octave / ~ 4 octaves)Modulation CV inputModulation destination:upper position: exponential frequency modulation (XM)lower position: linear frequency modulation (LM) or pulsewidth modulation of the rectangle (PM), selectable via internal jumperFrequency Modulation (FM) or Pulsewidth Modulation of the rectangle (PWM)Modulation intensityTriangle outputSawtooth outputRectangle output (about 50% without external PWM)Sync input (hard or soft sync internally selectable via jumper, C
