Intellijel Dixie II+

Analog triangle-core VCO/LFO with five waveforms

8 HP Eurorack module

The Dixie II+ is a fully analog triangle-core VCO/LFO capable of generating five waveforms plus a sub-oscillator square wave. It offers linear and exponential FM inputs, pulse width modulation, sync, and flip inputs, making it a highly versatile oscillator with a warm, organic character. Equally at home as a musical voice or a modulation source in LFO mode, it covers frequencies from several-minute-long LFO cycles up to nearly 60 kHz.

Features

  • Fully analog triangle-core oscillator design
  • Five waveform outputs: sine, triangle, zig-zag, saw, and pulse
  • Sub-oscillator output: 50% duty cycle square wave one octave below primary
  • VCO mode: 20 Hz to nearly 60 kHz
  • LFO mode: several-minute cycles up to approximately 1 kHz
  • 8-position octave switch for coarse tuning
  • Fine tune knob: +/-6 semitones in VCO mode, +/-7 octaves in LFO mode
  • FM1 input switchable between linear and exponential response
  • FM2 exponential frequency modulation input
  • Pulse width control via front panel knob (10% to 90% duty cycle)
  • PWM input (+/-5V) summed with pulse width knob
  • PWM can drive pulse to 0% or 100%, halting output at extremes

Controls & Jacks (21)

  • Fine— Attenuator for the FM1 input. Response type (linear/exponential) set by Exp/Lin switch.
  • Flip— Flips the direction of oscillator travel when input waveform crosses zero.
  • Pulse— Pulse wave output with variable width controlled by Pulse Width knob and PWM input.
  • Square Sub— Square wave sub-oscillator output, one octave below the base oscillator.
  • FM1 Attenuator— Fine tuning adjustment. In VCO mode: ±6 semitones. In LFO mode: ±7 octaves.
  • Pulse Width— Sets base pulse width of PULSE output from 10% (fully counter-clockwise) to 90% (fully clockwise). Square wave at 12 o'clock. Summed with PW
  • Sine— Sine wave output.
  • Triangle— Triangle wave output.
  • Sawtooth— Sawtooth wave output.
  • Sub Out— Sub-octave square wave output, one octave below the main pitch.
  • Sync— Resets oscillator to zero when input waveform crosses zero.
  • FM1— Linear or exponential frequency modulation input. Behavior determined by Exp/Lin switch.
  • FM2— Exponential frequency modulation input.
  • PWM Attenuator— Attenuator for the PWM input.
  • PWM— Pulse width modulation input, summed with Pulse Width knob. Range ±5V.
  • 1V/Oct— Primary pitch voltage control input, 1 volt per octave.
  • VCO/LFO— Switches between VCO mode (20 Hz to 60 kHz) and LFO mode (several minutes to 1 kHz).
  • Exp/Lin— Selects FM1 input response mode between linear and exponential.
  • EXP— LED indicating exponential FM input is active.
  • VCO— LED indicating oscillator activity.
  • Octave— Switch selecting the octave range of the oscillator.
