Frequently Asked Questions
The Quadrax is far more feature-rich, but the A-171-2 offers a simpler, more immediate workflow and a more classic, 'Doepfer' sound.
It’s surprisingly versatile; with careful tweaking, you can achieve very subtle, almost imperceptible changes in voltage, alongside more dramatic sweeps.
It's not huge, but in a system with many modules, it's worth considering, especially if your power supply is already nearing its limit.
