The MK2 Version of the 810 comes with several improvements behind the panel, but is cosmetically and functionally identical to the MK1. Like the 860 MK2, it has a steel back cover that fully encloses the electronics.
The System80 810 is a 30 HP Eurorack module consisting of a standard subtractive analog 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 analog, featuring elements of the System 700, System 100m, and the Jupiter-8. Add some modulation and an envelope generator to create a complete patchable analog voice with a distinctively vintage character.

Features
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

- VCO output and sub-oscillator normalized 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 normalized to VCF output
- Two CV inputs with selectable exponential or linear response
