Quick answers
Will the Derumbleizer work with my moving-coil cartridge?
Not yet — a moving-coil version is in development. The current Basic model is for moving-magnet cartridges.
My amplifier has no phono input. Can I still use one?
Yes. The Derumbleizer has a built-in RIAA phono preamp, so it connects to an aux/line input, sound card or stereo without a phono stage.
I lost my instructions. How do I set the capacitance switches?
Left channel: switch 1 = 50 pF, 2 = 100 pF, 3 = 200 pF, 4 = 400 pF. Right channel switches 5–8 match 1–4. Switches add capacitance when pushed down. You can also download the full instructions (PDF).
