The FXDf is a 6 Band Fixed Filter bank, oering simultaneous 6db/ Octave and 12db/ Octave inputs. The 6 lter

bands are spaced at roughly 11 to 13 semitones, covering a range of around 6 octaves. The FXDf is useful for

isolating a particular portion of the spectrum for mixing and analog or digital signal processing such as ring

modulation, amplitude modulation, pitch-shifting and reverberation. The module also has a header behind the

faceplate allowing for normalled connection of the 6 lter band outputs to the 6 inputs of RxMx allowing for

Voltage-Controlled, percussive, spectral animation. See page 4 for instructions on connecting the FXDf expansion

header to the RxMx.

In the past, the Serge System Fixed Filter used a 6db/ Octave lters, while the Moog Modular used 12db/ Octave

lters. We liked the sound of both lter slopes, so we implemented a way to use either or both simultaneously. In

this way, the FXDf also allows for blending of two audio signals. Traditionally, Fixed Filters are large modules

having 8 to 10 bands-- each with a manual level control, but rarely having any Voltage Control. The FXDf is so

small, we even had to abbreviate the words Fixed Filter! Also, by providing individual outputs, in addition to a

header for normalled connection to our RxMx 6-Channel Macro-Low Pass Gate module, Voltage Control over the

Level of each Filter band is possible through patching. We selected the 6 bands we found to produce the most

sonic energy within a typical Make Noise system patch. We also took care to space them wide enough that each of

the bands could be distinct from the others. This makes for quite an impactful sound when independently

modulating the amplitudes of the 6 bands using the RxMx or VCAs.

The FXDf contains 100% analog lters for musical applications and is not suitable for laboratory use.
