We have to admit being more than a little proud when thinking of the Action Filter's history. Twelve years ago we made the first version of this still popular stereo-filter with no end in sight. It still is built upon the same basic principle: ACTION!

Neither MIDI nor control voltage decide about filter sweeps and cues but you. Action Filter demands and supports your intuition and creativity. Reign over frequencies and rhythm instead of being a victim of technique.

What remains?

Like its predecessors, Action Filter 4 consists of a high- / lowpass filter-combination per stereo channel. Together, these either work as bandpass- or notch-filter with variable bandwidth and individual resonance per filter.

What's new?

Unspectacular but a spectacle nevertheless: Beside the mandatory RCA in- and outputs, Action Filter 4 is equipped with 1 / 4"-jacks. In addition, the FILTER MODE switch made it to the unit's front, labeled as STYLE.

Who is the Action Filter 4 dedicated to?

... of course for all action heroes! With jack- and RCA-connectors, Action Filter 4 is best suited for the DJ booth as well as for studio applications. You can use it to process full tracks or add that "certain something" to individual audio tracks. Emphasize or kill specific frequency bands and - on top of it - have lots of fun actively playing with frequencies! Simply: ACTION!
