Eurorack
Behringer – 110 – VCO/VCF/VCA – Notes
The Behringer 110 is a compact, faithful recreation of the legendary Roland System 100M 110 module from the early 1980s. It packs a complete analog synth voice—VCO, VCF, and VCA—into just 16 HP with internally normalled signal flow for instant patch-and-play fun, while still offering plenty of patch points for deeper modular experimentation. Perfect as a starter voice or utility module in any Eurorack system.

Key Features & Signal Flow
- Internally patched voice – VCO → VCF → VCA is normalled, so you can start making sounds immediately with just one patch cable (or none).
- Classic System 100M tone – Rich, punchy analog sound with that unmistakable 80s character.
- Flexible patching – Break the normalisations at any point and insert other modules.
- Dual VCA outputs – High-level line out + low-level “Eurorack-friendly” out for easy integration with mixers or other gear.
- Self-oscillating filter – Turn resonance up and the VCF becomes a sine-wave oscillator for extra tones or percussion.
