What did you buy after all?
Action Filter 4 is an analog stereo filter designed to mainly process complex
audio sources. This means, full tracks or loops will be processed entirely. Be
it in a DJ-setup or during studio productions, the
Action Filter 4 is a lot more
effective and versatile than typical Kill-EQs. We chose the word “ action ” in the
unit’s name because the filter is always operated manually. There is neither
MIDI- nor control voltage (CV) automation. Thus, the
Action Filter 4 demands
and supports your intuition and creativity.
A filter - what‘s that?
Before describing the functions of the Action Filter 4 ‘s knobs and switches, let’s
take a closer look at filters and what you could do with these.
A filter is an element that carves out specific portions of an original source.
This deadpan theoretical explanation is true for every filter: coffee-filters, color-
filters or audio-filters. While colors and coffee are sometimes topics during
lunch break, we are, of course, interested in filtering audio sources.
Up with the lowpass
Filters are differentiated by two basic types: Low- and highpass. These names
self-explain the operation methods. A lowpass filter will only let low audio
frequencies pass. The highpass does the opposite: It only lets high frequencies
pass.
The question now is: Which high respectively low frequencies? Who’s in
control? Good news - it’s you! The
CUTOFF control allows setting the cutoff-fre-
quency - the point from which the filter starts working. For a lowpass filter
this means: the lower
CUTOFF is set, the stronger the suppression of high
frequencies, meaning that the sound gets more muffled. Ergo, the highpass
filters works inversely: the higher
CUTOFF is set, the stronger the suppression
of lower frequencies, meaning that the sound loses bass.
