Great (stereo) sound in a small package.

I knew this filter would be good because it's basically a dual version of the filter on the ADDAC 4-Voice Cluster, as I understand it -- which is a great sounding little filter. Can be used dual mono or stereo, with true, tight high pass (I notice a lot of non-premium filters really phone in the HP or have noise leak, but not this one) and band pass, and a lovely, crisp, acid-y sounding low pass. I have an SSF Stereo Dipole and it took me quite a bit of patient tweaking with it to replicate the slick, crisp LP I was getting out of the ADDAC604. It seems to have a bit of inherent drive/saturation -- not enough to distort, just enough to keep the output warm and full-bodied. This was part of what was tough to match on the Dipole -- that and the excellent crispness of the mid-to-mid-high region at moderate resonance. Eventually I did match it (the Dipole is a very advanced and capable filter) but it took some work to get the same sound source sounding as good as it did through this modest little monster. Highly recommended if you want a stereo option without breaking the bank or using a lot of HP. Given its compact size there are of course some compromises, the main ones being limited modulation options (2 FMs only, 1 per channel/side) and wobbly trimmer pots instead of proper solid knobs. But there are no compromises sound-wise, it is a great sounding filter. Also, it is worth noting that this is completely different than the ADDAC702 Dual Filter -- it's not a "mini" version of that one. I have both and they are totally different from each other (and both great in their way). In fact in terms of just a straight-forward great sound for general use, this is probably the superior of the two; but in terms of flexibility and creative modulation options, the 702 obviously has more to offer there.

Charaktervolle Filtereinheit

Das ADDAC 604 Dual Filter ist zwar nicht der erste Filter meines Lebens, aber die erste Wahl im Eurorack. Für den Anfang wollte ich unbedingt die Möglichkeit des Stereobetriebs und das Switching zu zwei unabhängigen Einheiten. Das Ganze ist preislich offenbar recht ambitioniert, wurde aber im 604 Filter durch Einsparung anderer Features (große Regler, intensive CV-Steuerung) vernünftig bewerkstelligt.

Dass ich hier von High- über Band- zu Lowpass alles an der Hand habe und pro Strip auch getrennt einsetzen kann, stimmt mich sehr zufrieden. Dass der Filter absolut nicht versucht, seine eigene Meinung zum Signal zu verbergen und dabei mit der Resonanz sehr brachial klingt macht ihn als effektreichen Gefährten durchaus sehr individuell.

Der Offset beim Stereobetrieb hat mich erst irritiert, bis die Anleitung mich auf den Jumper hierzu aufmerksam gemacht hat, aber ist letztlich ja ein kleiner Bonus zum Design und der Verwendbarkeit.

Ein bisschen stören mich die Potis - nicht weil diese klein ausfallen, sondern, weil sie sich nicht so solide anfühlen. Ich habe keine Angst, dass sie kaputt gehen, aber sie fühlen sich zugegebenermaßen mit sehr wenig Widerstand und leicht wackliger Befestigung für meine Vorstellungen vielleicht etwas zu filigran an.

In der Summe ergibt das die obige Sternbewertung für mich, ich würde das Gerät aber auf keinen Fall missen wollen. Toll geeignet für Grit im Signal und mit der gut steuerbaren CV-Umsetzung am Cutoff auch gut für kräftige Drumsignale.
