Doepfer A-120

24 dB Low Pass 1 (VCF1)

Module A-120 is a voltage-controlled 24 dB low-pass filter, which filters out the high frequency components from a sound spectrum while allowing the low frequencies to pass unhindered. The cut-off frequency (corner frequency) determines the point at which this effect occurs. They can be set or modulated both manually and via control voltages (filter modulation, with an LFO for example). The VCF1 is configured as a "transistor cascade" with an edge slope of -24 dB / octave, which is also used in various Moog synthesizers, This results in the typical, "legendary" Moog sound. The resonance (emphasis) can be adjusted at the VCF 1 to the point of self-oscillation. In this case, the filter operates as a sinusoidal oscillator.

Great 'Moogy' filter

falafel 19.02.2020

Build quality seems a little flimsy. However It's great sound and low price make up for it 100%.

I was a little dissapointed

Kamil Z. 12.05.2016

They sell it as a Moog filter but they should mention it's actually more a Sub Phatty distorted Filter. Nothing compared to a Minimoog, Prodigy or even Rogue. I talked to a very nice person in Doepfer and he informed me these are changed to sound as such as customers asked for it which i get everyone is craving distortion now for some reason, but they should update their website therefore to let customers know.
I might keep it as some sounds comes out nice and meaty but othervise will not suit me for the purpose i bout it for (aka a Moog Filter) will need to find a replacement.

A120 Eine gute Investition.

Joan.Jamaivue 23.12.2020

Der A-120 erinnert im Sound an die Transitorkaskaden des MOOG und das zu wesentlich weniger Geld. Die Qualität der Hardware ist typisch Doepfer und es gibt nichts zu meckern. Einzig für die Bedienung der Regler braucht man schlanke Finger, sonst ist schnell aus Versehen was verstellt. Aber das ist eben auch A100 typisch.
Alles in Allem: Eine gute Investition.

Indispensabile

Filtro Low Pass da 24 db, come il leggendario filtro della Moog. A mio avviso questo della Doepfer riproduce abbastanza l'originale e suona benissimo. Difficile pensare un Synth senza questo filtro!
