The System80 810 is a 30 HP Eurorack module consisting of a standard subtractive analogue synthesizer voice: Voltage Controlled Oscillator (VCO), Voltage Controlled Filter (VCF), and Voltage Controlled Amplifier (VCA). While not strictly a clone, the design of each sub-module is inspired by the golden age of Japanese analogue, featuring elements of the System 700, System 100m, and the Jupiter-8. Add some modulation and an envelope generator to create a complete patchable analogue voice with a distinctively vintage character.
VCO
- Discrete Voltage Controlled Oscillator with temperature compensated exponential converter
- 1 V/octave tracking over 8 octaves
- Sync input with weak and strong oscillator sync modes
- 1 V/octave CV input + two attenuated exponential CV inputs for pitch/frequency modulation
- Five position octave range switch
- Selectable waveform output: Pulse, Ramp, Triangle, or Sine
- Pulse Width Modulation CV input
VCF
- Cascaded OTA design inspired by classic Roland topologies with selectable 12 or 24 dB response
- Self-oscillating with 1 V/octave tracking (3-4 octaves, normalised to VCO KYBD CV input)
- VCO output and sub-oscillator normalised to two log attenuated inputs
- Two frequency CV inputs, one unipolar and one bipolar
- Voltage controlled resonance
VCA
- Traditional single OTA design
- Three log attenuated audio inputs with IN 1 normalised to VCF output
-
Two CV inputs with selectable exponential or linear response
