System80 Jove - Matte black and gold

DIY System80 Jove filter module with matte black and gold panel.

Item was built by an experienced builder with quality components and tested and calibrated.

The System 80 JOVE is a premium 14 HP Eurorack module that accurately recreates the unique, versatile sound of the classic 1980s Roland Jupiter-6 synthesizer filter. Built using a modern operational transconductance amplifier (OTA) core, it delivers the iconic "chirping" resonance, aggressive sweeps, and smooth frequency response of the vintage hardware in a reliable, modern format.Key Highlights

• 4 Multimode Configurations: Instantly cycle between a sharp 24 dB Low Pass, a warm 12 dB Low Pass (reminiscent of the Jupiter-8), a textured Band Pass, and a precise High Pass filter via a simple push button.
• Onboard Audio Mixer: Features two summed audio inputs—one direct and one with an integrated volume attenuator—allowing you to blend two signals right at the filter stage.
• Dual Frequency Modulation: Equipped with two frequency CV inputs, including a dedicated bipolar attenuverter for easy inversion of envelope and LFO modulation.
• Voltage-Controlled Resonance: Includes a dedicated resonance CV input to dynamically modulate the filter's feedback from subtle warmth to self-oscillation.
• Open-Source Heritage: Fully open-source hardware with publicly available schematics, making it a favorite for DIY builders and synth modders alike.
