Frequently Asked Questions - Evolution Rossum Electro-Music
What is the Rossum Electro-Music Evolution?
The Evolution is an analog voltage-controlled filter (VCF) designed for Eurorack modular synthesizers. It offers a discrete, classic filter sound with modern flexibility.
How many filter modes does the Evolution have?
It features a variable slope switch that toggles between 12 dB/oct and 24 dB/oct low-pass, as well as high-pass modes. This versatility makes it suitable for both subtle shaping and aggressive filtering.
Can the Evolution self-oscillate?
Yes, when the resonance is turned up fully, the filter self-oscillates producing a pure sine wave. This allows it to function as an additional VCO in your system.
What are the power requirements for the Evolution?
It requires a standard Eurorack power supply with +12V (80mA) and -12V (50mA) via a 16-pin ribbon cable. Be careful with the red strip orientation.
Is the Evolution a true analog module?
Absolutely. The Evolution uses discrete analog components for the entire audio path and control circuitry, offering a unique, warm, and organic sound.
How do I install the Evolution in my Eurorack case?
Mount it with the included M3 screws to a standard Eurorack rail. Connect the power ribbon cable to the busboard, ensuring the red stripe aligns with -12V. Then power on and test.
Can I feed external audio sources like drum machines or guitar into the Evolution?
Yes, the Evolution accepts standard audio levels, including line-level or modular-level signals. You may need to adjust the input gain for optimal performance.
How should I clean and maintain my Evolution module?
Use a soft dry cloth to wipe the front panel and knob shafts. Avoid solvents or abrasive cleaners. Always disconnect power before any maintenance.
What is the warranty and repair policy for Rossum modules?
Rossum Electro-Music provides a limited warranty covering defects in materials and workmanship. For repairs or spare parts, contact your dealer or Rossum's official support.
Does the Evolution come with a user manual?
Yes, a comprehensive user manual is available as a free PDF download. It covers installation, controls, patch examples, and calibration details.
